ABSTRACT: With the development of a new, fast, bread baking method involving the
use of organic acids even ships without bread baking facilities, such as missile
ships, destroyers, escorts, and auxiliaries, can now make fresh bread. Jury-rigged
grills with open heating elements can be used as ovens. Detailed, step-by-step,
instructions on bread baking, including the best time for starting, how long to
dissolve the yeast, the maximum water temperature, kind and amounts of raw material,
optimum size of loaves, how to calculate proportions of raw materials for desired
amount of bread, as well as the time and temperature for baking of various grades
of wheat, are discussed. Missile ships and destroyers should be supplied with electric
ovens of the ESh-3 or ESh-3M type which are in production.

Methods for the production of compounds of rubidium and cesium and
ofthese metals themselves are reviewed. The applications of these metals
and of their compounds are outlined with parti.cular attention to uses in
photocells. C82Te, Rb2Te, and Cs 3Sb photocathodes are mentioned, as is
also the use of rubidium and cesi*am metazirconates Me2ZrO 3 and orthostan-
n4tes Me4Sn04 as luminescent substances in gas-filled electrical tubes.
The, medical applications of cesium eosinate are discussed on the basis
of-a French paper. An American patent is mentioned which proposes that
the piezoelectric properties of RbH2P04 be utilized and that furthermore
mixed crystals containing cesium, which are obtained from phosphate
solutions, be used as piezoelectrics.
A suggestion that the NaOH and KOH of storage batteries be replaced
.fully or partially with CsOH or RbOH so that these batteries will operate
more efficiently at low temperatures of.the order of minus 500 C is
discussed on the basis of another American patent.

In conclusion., the statement is made that ther#.are plentiful
supplies of raw materials containing rubidium and cesium and that the
p.roduction of these metals in the USSR should be expanded greatly in
the near futi-ire, notwithstanding the difficulty of processing some of
the.raw materials. Furthermore, the suggestion is made that carnallite,
which is used to an ever-increasing extent for the production of magnesium
and potassiwn, be also processed for rubidium.

ABSTRACT Among the numerous lithium minerals spodumene was above all, in.-
vestigated; its thermal properties were the most interesting:
fusibility and transformations at high temperatures. The fusion
point values obtained 50 Years age (1*8*-1o9*9) are too. low and
not up to date. About one decade later the area 22*,-98o* was re-
garded as zone of fusion (Endell and Rieke). In reality the spe-
cific gravity and the reflective index remain unchanged up to 92so.
At about 95** spedumene passes into a different highly symmetri-
cal modification. The volume abruptly increases by 24%. The speci-
fic gravity increases from d-3-147 (2 **) to d=2,,367 (13890),, Re-
fleotive index is n1-1.66 from 2o to 92*0,, then (at 98*0) it sud-
denly changes and increases to 1-519 and remains constant at hi-
gher temperatures., The authors call this zone- the zone of thermal
transformation- the spodumene. The new modification is irreversib-
le and polymorphous- The spodumene-modification found in nature
was called a-spodumene, the new one B-spedumene. This suggestion
is considered correct by the authors, as there are no ahemlaal,

ABSTRACT: Lithium is mostly isolated'as Li 2C03 from solutions which
contain common alkaline elements. Unfortunately, the mutual
systems Li 2so 4-N'~ CO3-H20 and Li 2s0 4-K2CO 3-H20 which come
into question here have hitherto not been investigated. The
great difference in the solubility of its two salt components
is characteristic of the triple system Li 2 so 4- Li2CO 3-H 20 which
forms a generating system of the two above mentioned systems.
This difference is reduced with the temperature rise. This
is of practical importance since the formation of Li 2CO3 is

and Li 2 CO3 turn out to be bottom phases at all investigated
zemperatures. The solution which corresponds to the eutonic
point is saturated with respect to the two last salts. It is
in equilibrium with the two compounds which are very different
with respect to the crystal size and the,crystal type. The

Conclusions: 1)The last mentioned processes of dehydration
and decomposition of zirconium-sulfate-tetrahydrate were
investigated by means of a) Heating in air up to the attaining
of a constant weight at various temperatures, b) Pyrometer
by N. S. l(urnakov, and c) a continuous balance. 2) According
to the velocity of heating, the dehydration of the tetrahy-
drate takes place either in 2 or 3 stages. In all cases, 3
water molecules within the range of 100 to 16ooC are cracked
at "a time. One watir molecule, on the other hand, is retained
more vigorously and escapes slowly at graduate heating; at

ABSTRACT: The problem referred to in the title was especially Inter-
esting from a practical point of view, There should be a way
to separate the adjacent pairs of elements which always
accompany one another (Li - Na, K - Rbq Rb - Cs). A literature
search revealed that statements made about the solubilities
of these al.kali chlorides are widely contradictory.. The
theoretical aspects of the problem are interesting, but the
practical are no less important, since single solvents can
work specifically and selectively and make it possible by the
solution of this particular problem to overcome other similar

phase that is insoluble in water, i. e. the solid phase,
consists of the following compounds according to
radiographic and thermal analyses: 1) anorthite,

pollucite can be divided into 3 groups: 1) acid methods, 2) direct
cesium production methods from oresq and 3) the methods mentionf-
ed in the title. A survey of scientific publications on said
method is given (Refs 1-13). The methods of the 3rd group,-
sintering and fusion, are at present not very numerous (Ref-13)-
This method mentioned in the subtitle has a number of advantages
over other methods, as the compound dosired by the toohnologiat
can be isolated almost directly. Howeveri with a low cesium
content (compared with other alkali metals), the reprecipita-
tion of 3CsCl.2SbCl3 or a preliminary fractioned crystalliza-
tion are necessary for a separation from sodium. The authors
employed said method of pollucite decomposition.-for.the produc-
tion of pure C9C1. Subsequently, the results.of the chemo-

p r o a e a a o f p o 1 1 u a i t e (Table I with CaO,

obvious that the laot-mentioned 4 chlorides cannot be used
as independent reagents for polluoite decomposition. CaCl 2
yielded the best results. However, the cesium yield from the
0
concentrate falls noticeably at 900 . The role played by
CaO must, however, not be underestimated. After all, CaCl 2
by itself is n~t able to fully complete the reaction. The
shift of the reaction is secured only by CaO , as it favors
the formation of Al and Si into insoluble compounds. Table 3
presents data thereon, as well as on the interactions with
other mixtures. The interaction of pollucite with CaO and
CaCl 2 yields the total cesium quantity in a water-soluble

ABSTRACT: In bo th natural and industrial materials hafnium is always
accompanied by zirconium. A survey of the numerous methods
serving for the direct dete=--lination of zirconium, suitable
for the hafnium determination as well, was recently given by
Portcastle (Ref 2). To dete=mine hafnium by these methods -it
is necessary to separate it f--am zirconium in the first place.
For this purpose it is best to use ion exchange methods ~Fef 1).
The determination of hafnium in the presence of zirconium can
be carried out by a few physical methods, as there are no such
completely reliable and specific reagents in analytical
chemistry to allow the detarminat-fon of Hf or Zr when oocu--r-J:',g
together (Ref 3). On the other hand, highly specific reagel-ts
for the sum of both elements havti been kn-own for a long time.

of zirconium, exclusively optical and radiospectroscopic
methods are used (Ref 4).Radiospect--roseopic analysis is
specially suitable for the quantitative determination (Refs -A-8).

zirconium can be carried out today by chemical, physico-chenical
and physical methods. The chemical methods are all indirect.
The present paper constitutes a very comprehensive synopsis
of the literature concerning all these methods for the
determination of hafnium in the presence of zirconium.

ABSTRACT: The investigations of pollucite (Refs 1-11) of the only mineral
containing cesium in greater quantities, are to a certain
extent in contradiction. Especially the structure of the mineral
and the position of water in its crystal lattice are un-
clarified. The author describes the synthesis of pollucite
from lithium aluminum silicate (P-spodumeneA and cesium
aulphate. In the case of heating to 950-1000 a product was
obtained which could be identified as pollucite by thermal,
optical and X-ray analyses (Table 1). Pollucite belongs to
the cubic syngony with a - 13.646 kX. The formation of pollu-
cite from a-spodumene was also examined. The reaction equations
for this case are given: a-(Li, Na) Afs 12 0 6j P-(Li,Na)~lE12,06]

ABSTRACT: The procedure (at high temperatures) mentioned in the subtitle
is one of the most popular among various methods of processing
pollucite to cesium compounds. Its superiority was confirmed
by the authors. They showed the role played by individual re-
action participants in the decomposition of the mineral
mentioned by technological investigation, and examined the
optimum conditions of interaction (Ref 1). The role played by
each of the constituents of the charge could be defined, and
the nature of the water-soluble components of the sintering
products explained by means of the results shown here. Pure
pollucite was used which was controlleO by means of cathode
Card 1/4 rays according to G. F. Komovskiy and 0. N. Lozhnikova (Ref 2).

The table (P 583) shows the results of the investigation
mentioned in the subtitle. Hence it appears that pure roasted
pollucite does not undergo any transformations between 20 and
V
9500. The ideas (still insufficient at present) on the charac-
ter of the interaction between CaO and CaC1, do not influence
the results.ar& conclusions. The heating curv'-es of mixtures
containing pollucite do not differ from curves of substances
or mixtures not containing poll-acite. Thus, they give no in-
dication as to the reaction process. The more difficult task
of deciphering the thermograms of the sintering products can
be solved by comparing the thermal variations of the initial
components and the thermal variations caused by the interaction
of the charge components with those depending on the properties
of the water-soluble salt system formed. The latter variations
are caused by the interaction of excess CaCl 2 with cesium- and
sodium chloride. These salts are formed because of the re-
action of CaCl 2 with pollucite (Ref 10). On account of the data
Card 2/4 on this interaction, an approximate computation can be made

of the CsCl- and NaCl-quantity formed by this reaction, and the
excess CaCl2 which together form the soluble salt system. The
thermal transformations in this system can easily be found by
means of heating curves with the use of the melting-point dia-
gram of the system NaCl-CsCl-CaCl 2' Upon comparison of this
melting-point diagram with data on the fusibility of the salt
mass of the sintering products, it may also be concluded that
the sintering of pollucite with CaO and Cacl 2 proceeds under
optimum conditions only if little melt is formed. This increases
the exchange deg-7-ee of the reaction. The thermogram of pollucite
with CaO is simplest among all thermograms of sintering products.
No reaction occurs between pollucite and CaG-CaC1 under optimum
conditions for the interaction of pollucite with he CaO-mixture.

TITLE: on the Interaction of Spodumene With Sulfates of Alkali Metals
(0 vzaimodeystvii spodumena s sullfatami shchelochnykh metallov)
PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 124, Nr 3, pp 642-645
(USSR)
ABSTRACT., A powder of thermally enriched spodumene ( 0-spDdumene) was
heated with sodium-, potassium-, rubidium- and oesium sulfates
over a wide temperature range in a muffle furnace. The water
extract of the product was tested with regard to silicon, and
was thermally, optically, and roentgenographically analyzed.
The reaction formula 2Li(AlSi 206) + Me2SO4 + Q cal ~
2Me(AlSi 206) + L'2304 (Me - Na, K, Rb or Cs) applies to all
sulfates with melting points beyond 10000 C. Lithium sulfate and,
as an insoluble phase, the aluminoBilicates of the individual
alkali metals (leucite, the rubidium form of leucite that does
not occur naturally, or pollucite) were formed. With sodium
sulfate, the reaction takes a different course. As it melts at
Card 1/2 only 8840 C, spodumene dissolves in the fusion into a

vitreous mass. This explains the well-known fact that sodium
cannot be employed in the decomposition of spodumene. On the
use of the other alkali sulfates, the formation of lithium
sulfate and of insoluble alumino silicate occurs in the same
way from natural (c)(, -) spodumene, as the last-mentioned
substance is converted into the A -modification by the action
of high temperatures. Therefore, a special preliminary
preparation of the /?-modification from first class spodumei_~-~,
or from flotation concentrates is unnecessary. This fa.:~t
constitutes the advantage of this method of decomposition as
compared to the sulfuric acid method that can only be carried
out with fl -spodumene, but takes place in a temperature range
which does not lead to the spontaneous formation of the
fl -modification. There'are 1 table and 11 references, 9 of
which are Soviet.

PERIODICALt Doklady Akademii nauk SSSR, 1959, Vol 125P Nr 22 PP 334-336

ABSTRACT: Spodumene constitutes the most important industrial lithium!
Bourcep and is characterized by the formula Li 2O-Al 20 3*4SiO2'
Howeverg the percentage of the components in spodumene varies
as it never occurs pure (Refs 1, 2). Many elements are present
in spodumene as isomorphic substituents# and cannot be removed
mechanically (Refs 2, 3)- Most of them replace lithium in the
crystal lattice. From the processes in nature it becomes
obvious that this lithium replacement can attain significant
dimensions (Ref 4). This is the main characteristic of spodumene
erosion by which the mineral is deprived of its value. Sodium
plays the most conspicuous role in this process. Although
spodumene for a long time used to figure with the alumo-
Card 1/3 silicates, there is no doubt today that it constitutes a double

silicate of lithium and aluminium (Ref 5). Natural spodumene
(mostly called C&_Sipodumene) is characterized above all by
the monotropic transitionv between 950 and 11000, into a
high-temperature modification ( 13 -modification or 13 -spodumen4
Ref 7). This irreversible transition is of great practical
importance, as in the roasting of spodumene-containing rocks
it can be employed for their enrichment in lithium. 'Unlike
cK.-spodumene the A -modification is brittle and comminutes
easily. Thus a concentrate can be obtained by means of sifting.
Contrary to the case of the a(-modification there are no
conclusive data on the structure of #4 -spodumene. It may be
assumed that the symmetry of the latter is hieaer. The authors
made an x-ray study of the latter. The results (Table 1) can
be considered satisfactory only for 54 lines of the x-ray
photograph. The paper under consideration was started under
the direction of the late Academician G. G. Urazov ( for
many years Head of the Kafedra tekhnologii tonkikh
