The effect of geometrical E202/E,420
water was determined chemically since the mechanical separation of
mercury was thought not sufficiently accurate. The samples were
taken during a steady reduced velocity of the lighter component
reached in a steady supercritical condition,of bubblingo It was
fouad that the geoihetric characteristics af.the perforated plate
has a very complex effect on the entrainment of the heavy
component. The curve relating the relative entrainment w to
the relative open cross section of the perforated plate y had
at w.= 0.06 m/sec a well defined minimum at (pmin
The main difference of the two component streams in the suberitical
and supercritical regions lies in the difference of structure of
the bubbled layer. In the subcritical flow this layer comprises
a stable turbulent mass of the heavier component with separate
droplets of the light component. In the supercritical region of
flow the roverse is true. The change of structure takes place
when. the critical value,of the light component velocity is reached.
Three types of ertrainment were obso*rved* 1) foam entrainment,
characteristics for low velocities.and small separating volumes;
2) "dust" entrainment and entrainment of very fine droplets for

which the ve'lOcitY Of fall of the'drOplets'does not exceed the
velocity of the entering streams.and 3) splash entrainment which
takes place as a result of mechanical breaking of droplets of a
larga size which Is observed in separators the height of which is
smaller than the height of splash of'the droplets The second
mode of entrainment was most effective. It was ;lso found that
at low values of y the light component enters the layer wIth-
relatively high velocity, the number of 'centers of entry being
distributed along the surface of the perforated plat6. The flow
of such streams takes place without-noticeable interaction and
displaced droplets of mercury fall freely in the space between
-these streams. Strong water streams-penetrated the layer,
forming in it separate channels'through which passed a continuous
flow of water. There are 4 figures.

Aqueous Solutions(Isaledovaniye usloviy obrazovaniya i

PERIODICAL: Doklady AN SSSR, 1957, Vol. 117, Nr 1, pp. 88-91 (USSR)
ABSTRACT: From other publications it is well known, that Pu (III)
shows much less preference for the formation of complexes.
The authors studied the stability of solutions of oxalate,
carbonate, citrate and ethylene-dianine-tetra-acetate
complex compounds of Pu (III) against oxydation by the
oxygen of the air by spectral photometric methods. It
appears, that Khindmen was correct with his assumption,
that complex formation cannot cause a noticeable modifi-
cation of the absorption spectrum of Pu (III). After the
authors having established the conditions of the above-
mentioned stability, they approached 'he problem of the

constant of the complex ions of PTJ (III) with various
complex constituents. Two methods were employed: a) the
method of solubility (at pH 8) and b) the method of ion-
exchange (at pH ~ 1'4 - 310). a) At first the solubility of
PU 2(0204 )3 - 9H20 in aqueous solutions of K 2C204 at 200C
and at a constant ion density of the solution was
determined. Pu (III) was protected against oxydation by a
nitrogen jet. The plutonium contents of the solution were
determined by radiometric measurements. The results are
given in table 1, from ffh1ch the composition and the general
instability constants (reference 6) of the oxalate complex
ions of Pu (III) were determined or computed, respectively.
In the range of concentration of K 2C 204 under investigation
complex ions are formed (more exactl a relation between
Pu (III) and the C 204-ion): /Pu C 204V_'1PU(C204)5 /I and

tion of the ions in question on the concentration of the

In an analoguous way the solubility of Pu2(C204) 3' 9H20
in aqueous solutions of (NH 4)2C204in the range of concentration
of the ammonium oxalate from 0'07 to 0'7 Mol//l at 700C
was determined (table 1). In this process complex ions of the
same composition are formed, the total instability constants
of which for Pu 2(C204 )21-1 1,6.lo-9, for /Pu(C204)3/3-5,6. 10-9,
and for Pu+(C20 4)4 /5-2,5. 10-9 are equal. The heat of

52-56. 1----------
The method of ion exchange is used to study the oxalate complexes of
Pu3 in th pH Interval 1.4 to 3.0. It is established that in this pH
region, there are formed the complex ions CPU(C2q4)27 and
f7PU(HC204.)g , wholl instability constants are KI - 71 x 10-10
and V I - 1* 1. x 10- . The value of the instability constant of the
complex ion f-Pu(C204)2 _7 is in satisfactory agreement with the value
of the instability constant of the corresponding complexion, obtained
by the solubility method.

ABSTRACT.- The authors Investigated basic regularities of irreversible changes in
the dimension and shape of Al (99.7% Al) subjected to a periodic tempe-
rature action. The authors investigated the dependence of these changes
on the number of thermal cycles, the heating and cooling rate, the tem-
perature range, preliminary plastic deformation, grain size, dimensions
and shape of the original specimen. The cyclic temperature action was
brought about by transferring the specimen from one temperature zone Into
another one. The time of transfer was two seconds. It was established 1_
that an increased number of cycles caused usually increased deformation"
of the specimen and that this augmentation was proportional to the number
Card 1/3 of cycles. A higher cooling rate furthered the increase in the coefficient

of growth, equal to one cycle; however, higher heating rate raised the proneness to
contraction of the specimen. Ritised temperature ranges caused a noticeable increase
In the coefficient of grwoth. For annealed and rolled specimens the temperature
dependence of the coefficient of growth was different; this was particularly notice-
able within the range of temperature drop of 3000C. In preliminary deformation to
50% the coefficient of growth increased 4 times, compared to the initidl value (non-
deformed specimen). Annealing of the specimen after preliminary cyclic thermal action
entailed a considerable rise of the coefficient of growth. Different grain size caused
a difference in the coefficient of growth only under conditions of speeded-up heating
and slow cooling-off. Generally, deformation of large-diameter specimens was higher if
the InitW diameter changed during a given number of cycles, although such dependence
was rather complicated in a number of cases. During the tests the authors observed
intensive dislocation, migration of grain boundaries and sometimes crack formation. The
conclusion is drawn that irreversible changes in the shape are due to relaxation of
stresses arising during the heating and cooling process. These stresses may develop on
account of the temperature gradient along the cross section of the specimen, whose

surface is at first rapidly heated up (in speeded-up heating) and then tends to expand,
Stresses may cause plastic deformations, and since the periphery is heated up more than
'the center, the specimen may turn out to be plastically compressed. In the case of
speeded-up cooling of the heated specimen, the effect of stresses is rever2ed and the
specimen may deform plastically In the direction of the expansion.

this work the authors give the determination of the composition
a well as of the instability constants of Pu (IV) as mention-
:
d in the title. 4-6 hours are sufficient to reach the equilibr-
ium between the ammonium-oxalate solution andithe solid phase of
Pu (IT) oxelate at 2o t o,o2O. The experimental results are nen-
tioned in table 1. The solubility of Pu (IV) oxalate decreases
with the increase of the concentration of aamonium-oxelate from
0,001 to 0,005 Rol/liter, it reaches a minimum of 3,55-jo-5 mol.
Pu(IV) per liter and then increases because of the complex for-
mation of Pu(IV) with oxalations. The solubility is expressed by
means of an equation (I). Complex ions with general instatUity

constants correspond to different decomposition schemes (2) and
(3). Tmqble 2 gives the solubility of Pu(IV)-oxalate in water
and in H 304, HU03 and HC104' From this follows that the solubi-
lity, bu? that then, starting from 0,1 N , it increases again.
Because of their interaction with the oxalate in aqueous solu-
tions the acids form a series: H230@4 HIIO@HC104. The pH of a
saturated Pu(IV) oxalate solution wa equa to 4,4, the molecu-
lar electric conductivity 470!2-1. The dissociation process of

In the present paper the solubility product (SP) of the compound
UO2 C204* 3H20 and the complex formation of uranyl with oxalate
ions were investigated. The solubility of uranyloxalate in HC10 4
and HNO 3 solutions of different concentrations as well as with
Card 1/4 additions of oxalic acid or ammonium oxalate was determined by

the usual solubility method. As the data contained in table 1
show, the solubility decreases as the oxalate ion concentration
increaseso so that no complexes form in the range of concentration
investigated. Table 2 lists the values of the equilibrium
constants, table 3 those of the SP. As the graphic representation
of the relationship betwoon the logarithm of the concentration of
the oxalate ion and the logarithm of the mineral acid conmntra-
tion shows, the S equals 2.2.10-9 in the presence of chloric
acid, and 3-0.103 in the presence of nitric acid. The determina-
tion of the solubility of uranyl oxalate in oxalic acid and
ammonium oxalate solutions, respectively, with additions of
chlorio acid or nitric acid (Tables 4, 5) point to complex
formations according to the general equation

The graphical evaluation of the data (Figs 2, 3) showed that
predominantly a oomplex with a component ratio of uranyl ion:
oxalate ion - I : 2 forms. This complex formationo however, takes
Card 2/4 place in the case of hydrogen ion concentrations below 2 mol/l only.

Uranyl in Oxalate Solutions by Means of the Solubility Method
The equilibrium constants of the complex formation are listed
in table 6. The investigation of the solubility of uranyl
oxalate trihydrate in ammonium oxalate solutions without any
additions of mineral acid (Table 7) showed that here complexes
of the same composition are formed. The following equation was
established for the dependence of the solubility of uranyloxalate
2
on the concentration of H+ ionst [al . 7.35 H2C20 4*
By means of this equation the most favorable condition for the
precipitation of uranyloxalate from solutions in the presence of
mineral acids can be determined. T4_respective instability 2-
constants of the oxalate complexes U02C2041 and IN2(C20 4)2]
are given as (1.7tO-3).10-7 and 0.010.3).10-12 for the
oxalate ton concentration range under investigation. The

with the ion exchange method under the following conditions:

may see that with increase of the Z the strength of the

the solubility of the Pu(IV)Vhosphate was determined hi-
oally from experimental data for the solubility of PuriaMhos-
phate in mixtures of HNO 3 and H3P04 (fig 3). The mean value
of the solubility product determined according to the three
methods in 2.10-28. A comparison between the solubility
product of Pu(IV)phosphate and the corresponding Th- and
U-oompounds shows that the Pu-conpound has the lowest solubi-
lity because of its lower ionic radius. There are 3 figures,

TEXTa In order to obtain stable solutions of nitric acid when dissolving
the fuel elements consisting of an uranium-molybdenum alloy of the first
atomic power plant of the USSR, 20-40 g1l phosphoric acid is added. This
caused the authors to investigate the complex-formation of plutonium (IV)
in solutions of phosphoric acid and to determine the ratio between metal
and addend and the dissociation constants of the complexes. They in-
vestigated the solubility of the gelatinous Pu(HPO 4)2'xH2o in 0.012 to
2 mole/l phosphoric acid in the presence of 2 M HNO 3 at 25'C. The ex-
perimental data are shown in Table I and Fig. 1. The solubility of

PERIODICALs Inzhenerno-fizicheakly zhurnal, v, 4, no. 10, 1961, 111-114
TEXTo The authors studied the thermal fatigue of cylinders of 99.97%-pure
copper which were subjected to a cyclic thermal treatment, The specimens
were put into a furnace, kept there for about 5.7 min, and then chilled in
100C water for 2 min. This process was repeated cyclically. After about
1000 oycles over a temperature inter-tal of some 500 0C, the thermal stresses
led not only to a crinkling of the surface but also to a relative
deformation (elongation) of the specimens by 5 - 7%. The relative change
in the apparent density of the specimens rised with the number N of cycles
according to a parabolic law, The anomalous course of the curve
corresponding to cycles over an interval of 400 0C could not be explained.
The relative change in density was due to thermal fatigue which causes

observed in the regions of the highest thermal stresses. Measurements
showed a relative change in density of 2.75% cn the surface and of 2% In

study was carried out statically by observing the distribution of NPV
used as indicator between a 0#05 N solution of RH 4clo4 and the KY-2 (KU 2r'

of complexing agents. The experiments were performed at 20 1 20C. The
grain size of the cation exchanger was 50 - 70 mesh. The pH of the solu-
tion was measured with a glass electrode and the ATT-5 (LP-5) pH-meter.
In a pH-range of 2 - 5 NP V wa3 found to form complex ions of the following

PERIODICAL: Zhurnal neorganicheskoy khimii, v. 6, no. 8, 1961, 1815-1820
TEXT: The complex compounds of neptunium with oxy-acids have been little
studied. Only Yu. A. Zolotov and Yu. P. Novikov (Ref. 1i Zh. neorgan.
khimii 6, 1055, 1961) detected a change in the absorption spectra of
neptuniu.m solutions in the presence of complex-forming substances. The
complex formation at different pH va:.ues was studied by cation exchange
between pentavalent neptunium in 0.01@ molar NH 4CIO4solution and the
cation exchanger 93-2 (KU-2) in ammonium form in the presence of citric
and tartaric acid. TI)e pH value was measured with an 11'ff-5 (LP-5) pH meter
with Rlass electrodes. In the pH range 4.5 - 5.2, neptunium (V) was
founa to form the following complexes with citric acid: NpO 2Cit2- and
NpO HCit with the stability constants (4-7 t 1.0)-103 (pK = 3.67) and

solutions in the presence of citric acid at PH - 0.9, 3.5, 5.1, 5.7, and
6.1 were recorded. The absorption maximum at 963 mp was found to shift
due to complex formation to the side of increased complex formation. The
complex formation in the system neptunium (V) - tartaric acid was deter-
mined by a change in absorption spectra of neptunium (V) solutions in the
presence of tartaric acid at different PH values of the solutions. In
the PH range 3.2 - 6.2, neptunium - tartaric acid complexes of the
following compositions were determined by cation exchangeo NpO 2HTar,
NPO Tar-, NpO Tar3-, and NpO Tar5-. These complexes have the following

Although no complete data exist for-11p(V) and Pu(V), this aequence can
also be applied for these elements owing to conformance of instability
copetants. Instability constants of complexes formed by Pu of different
valence'with the same addend show that Pu in the pentavaleat state has the!
weakest tendency to form complexoa. On the basis of the similarity of
complexing properties of pentavalent Pa, Np and Pu, and of the
qu@antitative data available, conclusions may also be drawn as to the
composition and stability of complexes of pentavalent uranium with the
acids mentioned. One of the properties of actinidea which serves to
prove their position in the periodic sy8tem of elements is their behavior
during ion exchange. Pa, lip an'd Fu in, peatavaleat state were found to
behave similarly during ion exchange#. 'Thera are I figure an(i I table.

ABSTRACT: Amzwn1wm plutonyl phosphate was precipitated by the reaction
of a 0,1 molar nitric acid plutonyl solution with an 8.26 x 10-5 molar
concentration of the metal and a 1,0 molar solution of (NH4)aHPOI,e The
finely crystalline precipitate obtaineds which was of a light griren
color and had the composition NH4Fu02P04-3H20P was the starting materi&
for the investigations, The soldbillty of ammonium plutanyl phosphate
was determined in aqueous solutions over the pH range from 1.0 to 6.4.
In one series of experlmnts the pH of the solutions was adjusted by
addition of HG1Oh# and in another series of experiments by addition of
HWOi* The Ionia-ratrength in the solution was not aonstantp since
add tion of N010h or LiNO3 to maintain mm constant brought about

" July 3, 1958. It was organized by the Physics Institute Imeal
P.H. Leb6dev of the Academy of Sciences of the U.S.S.R. and by the
Scientific Coun@.Al on Luminescence. The conference was devoted to
the physics , chemistry and applications of crystal phosphors . Over
360 delegates from 24 cities &no towns in the Soviet Union attended the
conf3rance. Hanirarian, Polish and East German scientists were also
present. Over 100 papers were read at 4 plenary and 14 sectional
Sessidna. Tne conference was split into two parallel sections an the
physics and on the ch6mistry of crystal phosphors. %pars on the
ph@sics of crystal phosphors could be divided into the following grouass
(1 nature of the luminescence centres, (2) processes of transfer of
energy in crystals, (3) kinetice of recombination luminescence and the
naimrs of capture centres, (4) physical processes occurring on
excitation -with electric fields, electron bows and hard radiationa.

PERIODIC;L: B.ton i zhelezobeton, 1957, Ho. 1, pp. 28-29, (U.S.S.R.)
ABSTRACT: The corrosion resistance of steel is affected by the quality of
the concrete used, and decreases with decreasing alkalinity,
i.e. when the hydrogen ion concentration falls below 9.5
which can occur due to the carbonization of the cement matrix
which is in direct cdatact with the reinforeemtfAt. Th 'e degree
of carbonization dVends on the permeability of the protective
layer, the permeability being a function of the density and of
the thickness of the layer. Considerable reduction of the
permeability can occur during autoclave curing, especially
when cement containing silica additives is used. In all these
cases the degree of corrosion is influenced by the thickness of
Card 113 the protective layer both during the initial stages of the hardening

protective layer. Various methods devised to achieve this protective
coating were submitted to the authorities, e.g. the coating of
the reinforcement with a cement slurry containing various additives,
coating with a layer of bitumen, ate. The first method did not
prove to be successful, the second method, although more advantageous,
has the following disadvantages: the adhesive properties of the
concrete and the steel are not utilised, it Is difficult to ensure
the coating of all steel surfaces, and there is the undesirable
affect of heat on the bitumen during autoclave treatment. The
best method of protecting steel surfaces appears to be the
Oneutralisation" of the surfaces of the reinforcement. Ordinary
concrete, due to its high degree of permeability, acts as a
"neutraliser". Experiments were carried out to bring about this
*neutralisation" artificially. Various inorganic salts are known
to act as oxidising agents and thus act as Oneutralisersw,
Card 2/3 e.g. chlorides, nitrates, phosphates and some alkaline metal salts.

Investigation showed that the best additive is Na nitrate which
is added to the cement mix (2-3% by weight 6f cement.) Coating
with this chemical substance proved unsuccessful during autoclave
treatmeht. NaK02 did not have an adverse effect on the physical
or the mechanical properties of the concrete in the above proportion.
