vanadium, nioblus and tantalum monocarbides which were prepared by sintering. Can-
duction In these monocarbides was found to be metallic'In character and due,to free,
electrons. As the carbon content (i.e., the number of car6on vacancies) of the
sonocarbLdes changes, there Is a cha.nge both in residual resistivity and In the
slop* of the temperature dependence of the resistivity and thermal eaf; there is a
drop In carbon content in the region of homogeneity of the manocarbides. This can
be interpreted by assuming a decroase In the density of states and in the rate at
which the area of the Fermi surface changes with the ens~qW on passing from carbon-
rich sonocarbLdes with the prevalence of directed N-C bonds to carbon-pcor monocar-

ABSTRACT An attempt is made here to determine the relation between the elec-
tronic viork function in thermoemission and the electronic structure
of transitive metals ( and their compounds with :b*oron carbon
and nitrogen). It is shown that the work function depends on the
atomic structure of the metal and decreases with decreasing degree
of screening of the electrons of incompletely occupied d-atom shells
of transitive metals. The work function can be broa6ht into connection
with the quantity of dispersive power of the atoms of transitive me-
tale which are characterized by the criterion 1/11n. 11 - chief quantam

of transitive metals with bor6n , c arbon and nitrogen the work func-
tion should increase with increasing 1/Nn for the corresponding
41ransitive metals.This is confirmed in the case of borides,but in
the case of carbides and nitrides it can not yet be considered to be

ABSTRACT: Investigations of magnetic susceptibility of metal-like com-
pounds can contribute to an explanation of the nature of
chemical bounds in these phases. The authors investigated
the magnetic susceptibility of the single-phase solid solutions
of the following metal-like compounds: ZrC-NbCl TaC-NbC;
TaB2-ZrB2 and TiC-TiN. Since the measurements of absolute
susceptibility were difficult due to experimental conditions,
the values of relative susceptibility were determined by
taking that of one of the components for unity. The results
of experiments are presented in graphical form showing the
dependence of magnetic susceptibility on the concentration.
The two curves for the alloys NbC-ZrC and TaB2-ZrB2 have peaks,

ABSTRACT: After a discussion of papers and discoveries in this field
this paper gives the results of the measurements as well as the
production of borides from Dy 2039 Ho2030 LU2039 Gd2 03 and Er 203'
The production was carried out from the mentioned oxides with
boron carbide at 1400-16000 C in vacuum furnaces; the phases of
the obtained products were identified and the corresponding
formulae were determined as follows: GdB V DyBV HoB6, ErB6'
LuB6 and GdB 4, DyB 4, HoBV ErB4, LuB4. The authors found that
the metal is in bivalent form in the case of CaB 6' BaB 6' SrB 6'
YB6 and ErB 6' while it is in trivalent form in the other hexa-
borides of the rare earth metals. This was determined from the
Card 1/3- obtained values of the lattice parameters of hexaborides as welli

as from the lenghts of the bindings Me-Me, Me-B,and B-B calcu-
,kted herefrom. It was noticed that the Me-Me and Me-B bindings
decrease in every period at the transition from the bi-zb the
trivalent metal, and that the weakening of the bond in hera-
borides can be explained by an increased concentration of the
free electrons which weaken the lattice. The stability of the
lattice MeB6 is due to an especially strong binding of the
boron atoms. The assumption is made that the formation of a
hexaboride is possible also with elements with a higher ioni-
zation potential; this is, however, connected with difficulties
as was shown by the experiments for the formation of silicon
hexaboride. There are 1 figure, 3 tables, and 21 references,

ABSTRACT: In the present work the phase composition of Re-B alloys was
investigated as there is practically no reference to be
found in publications (with the exoeptioa of a short
mentioning In ref. 1). These compounds are first of all of
interest as they might be similar to the stable# difficultly
smeltable and hard tungsten borides (ref. 2) as well as to
the unstable manganese borides. Alloys were investigated
which had been calculated with a view of producing oompoundog

regards their electron structure and their properties. Th*y

satisfactory coincidence of the structure of the Phagos
produced with the known boride phases was obtained.
Beginning with composition Re4B a gradual lattice trans-
formation of rhenium is observed. Besides the considerably
washed lines of rhenium a certain amount of additional
weak lines appears which also appear washed. With a further
increase of the borine content to 33 atomic-% these lines
become clearer. A further increase of the content of borine
brings about a gradual change of the radiogram. Beginning
with 50 atomic-% all radiograms look the same. Although no
essential changes of structure are to be noticed with the
transition from one alloy to the other the radiograms of the
alloy-samples far from each other are markedly different.
In system Re-B two phases can be assumed: 1, within the range
of 20-35 atbmio-% and re within the range of alloys with more
than 40 atomic-%.B. The last phase could not be identified
hitherto. The alloy with 33.3 atomic-% B immediately after
sintering had a structure corresponding to the e-phases of
me2B5', After storing in the air for I month it passed over to

ABSTRACT: Recently, the parameters of the thermoelectront emission of
nearly all hexaborides of earth-alkali metals and rare earth
metals have been investigated. A diagram (Ref 4) shows the
dependence of the work function of hexaborides of rare earth
metals MeB6 on the nuclear charge number of their metal com-
ponents (according to data obtained by G. A. Kudintseva and
B. 11. Tearev). The character of this dependence can be ex-
plaind satisfactorily by the theory of the atomic structure
of rare earth metals developed by N. A. Tellyashevich (Ref 5)
as well as by the theories developed by various authors con-

boridea is connected with the double ionization of metal
atoms and with the transfer of 2 external a-electrons by a
boron atom. In this way 5 covalent bonds are produced in the
boron-octahedra and between them. Reference is made to several
earlier papers dealing with this eubject. Next, binding
between metal atoms and boron tt~)ma is brought about by
meana of an electron collective. which is formed by the elec-
trons of normal or excited d-orbits and partly also by such
electrons as belong to the s-orbits of the metal as are not
utilized for binding with boron. It is necessary, in the
hexaborides of rare earth metalsto investigate two systems
of energy bands, viz. the narrow only slightly excited
4f-band and the comparatively broad hybride 5d-6d-band. The
latter must determine electric conductivity and the work func-
tion of the electrons from the hexaborides under investigation.
Several details are then dealt with. The above mentioned dia-
gram also shows the number of possible terms for 4 f-electrons
as function of the nuclear charge number of the metals,
which were calculated according to the rule

yttrium has been expanded In the recent time, but still it is hampered by
their relatively low electric resistance. One of the possible ways of
Increasing their electric resistance is the use of their alloys instead
of individual borides ZH-ef 2,7. The authors prepared alloys of hexaborides
or lanthenum and cerium by hot pressing the mixture of their powders under
a pressure of 15o kg/cm2 and at temperatures of 1,600 to 2,OOOOG. The
sintered samples were subjected by an X-ray analysis in the RKE chamber,
end the data obtained are presented in Table 1. The roentgenograms do
not reveal characteristic lines of individual borides but two lines of
their solid solution are ooserved. The specific electric resistance of

using a method described previously (Ref 6). The chemical
and phase analyses are given in Table 1. The samples were
made on a laboratory press without any special protective

the reaction of 'chromic oxide and boron carbide. The che-.icFll
composition of chromic boride is given in-table 1. The

This change in weight is a function of the time of

by Kotallnikov (Ref 14) corresponds to the one in the
present paper. The coefficients of expansion of three samples
with different Dorosities at 5000, as well as the resistance
to pressure and rupture of chronic borida samples with
different porosities, are further indicated. Some properties
of the chromic boride are given in table 2. Concern-4ng the
stability of the chromic boride against the action of
active reagents, the authors of this article refer to the
papers by Kotellnikov (Ref 14) and Modylev3kaya (Ref 22).
The indicated properties of the chromic boride permit its
use as a constituent of heat-resistant alloys. A shortcoming
is its brittleness which can be reduced by cementing the
boride grains with a metal binding agent. The cemented
chromic boride can be used for the manufacture of nozzles for

ABSTRACT: This is a revised version of a lecture given by
Candidat4,,of Technical Sciences G. V. Samsonov in
Prague ia.-'-,the Spring of 1958. The high hardness of
compoundWd.f a metallic nature like carbides, nitrides,
borides aml-silicides of the transient metals of the
fourth to bh& eighth group of the periodic system is
one of the most characteristic properties of these
substances.'-.In view of the high brittleness of these
compounds, Microhardness measurement appears to be the
only suitable method of investigating their hardness.
Earlier results obtained by the authors 'of this paper
and other authors were published in earller work
(Refs 1 and 2). In this paper the authors describe
their studies'on the influence of loading of the diamond
pyramid during measurement of the microhardness by the
Soviet FMT-3 instrument on the measured mierohardness

from the characti;r of the indentation on the surface
of test specimens during the indentation with the gyramid.
The measured values of the microhardness, N kg/mm ,
obtained with loads of 20 to 200 g and of t e micro-
brittleness Z for 31 carbides, nitrides and silicides
are entered in Table 1, p 485. The microhardness
studies of very hard substances, described in the paper,
prove that a clearly defined relatioa exists between
the microhardness and the magnitude of the applied load
and this can be clearly seen from the data entered in
Table 1 and from the graphs, Figs 1-4. The brittleness
of the compounds was measured by a microhardness method
described by N. 1. Ikornikova. (Ref 15). The method
consists of making imprints with a diamond pyramid with
various loads and evaluating the number and the
character of the produced cracks and other detects.
The thus determined results are entered in Table 2, p 488.
It was found that the dependence of the microhardness

with relatively low hardness values and appears to b

governed by the character of the plastic deformation of
the surface of the hard materials during the micro-
hardness measurements. The brittleness characteristics
determined in the work described in this paper are in
agreement with brittleness values determined for some
compounds by, other authors. The brittleness increases
with decreasing square value of the defection of the
centre of the molecular complexes during thermal
oscillations in the crystal lattices of the compounds,
i.e. it increases if the strength of the interatomic
bonds increases and if the stress relaxation in the
material decreases. The hardness of compounds of a
metallic nature increases in the following order:
s'licides, nitrides, carbides, borides, whilst the
brittleness increases in the following order: silicides,
borides, nitrides, carbides.

TEXT: Published data relating to the electric resistance and the work func-
tion of transition metals and their compounds with B, C. Na2 and Si are analyzed.
Electric resistance of metals increases with the growth of the value (I/zd n),
where Zd is the number of electrons In a vacant shell and n is the maL~quantum
number. This is connected with an increased shielding effect of defective shello.
For metals the work function decreases with an increase of k. For refractory
+,compounds of carbide, boride and nitride type these dependences have a reversed
..~character, which is connected with the filling up of the holes in defective orbits
by metalloid electrons and the corresponding decrease of the shielding effect.

ABSTRACT: The electrons necessary for tis formation of the 5 covalent
bonds in the hexaborides cannot be supplied by boron)alone,
two of them must be supplied by the metal (Refs 5, 6 . The
formation oftbe hezaborides probably depends on the first
and second ionization potentials of the metal. The values
of the potentials determine the attractive force of the
two valence electrons. In table 1 the ionization potentials
of the metallic elements of the periodic system are listed.
It is concluded that all the metals having first ionization
potentials below 6.6 " 6.8 ev, and second ionization poten-
tials below 11.5 - 12 ev are able to form hexaborides. In
Card reference 8 it was proved that the bivalent metal in the

hexaboride may partially be substituted by sodium. The
highest electron concentration at which this substitution

it follows that the bond of the borine in MeB 6 requires
1.6 electrons, the remaining 0.4 electrons per metal

explain the comparatively high electrical conductivity
of the hexaborides of bivalent metals. There are I table

ABSTRACT: The author discusses the relationship between thermal
properties of solids (eg melting point, Debye
characteristic temperature, coefficient of thermal
linear expansion, thermal conductivity etc) and elastic
properties. Such relationships are important in
estimation of mechanical strength of solids at
elevated temperatures. Using formulae established
earlier (Ref 2,4,5), the author deduces

Experimental points taken from published work (Ref 2,5s7

that Lindemann's formula does not represent a
mathematically correct relationship between 9 and Ts
and expresses only the fact that. at given values of the
molecular weight, solids with high melting points have
high Debye temperatures. To find an improved relationship
between the Debye temperature and the melting point, the
author used Eq (4) and the relationship between the
coefficient of thermal expansion and the melting point.
The latter relationship is shown in Fig 3. The points
representing metals with cubic and hexagonal closely
packed lattices and metal-like carbides, nitrides and
borides of transition twetals lie on the lower curve of
Fig 3. The points representing alkali halides lie on
the upper curve of Fig 3, because their linear expansion
coefficients are higher (higher repulsive forces exist

compounds and k =~0-115 for alkali halides. Substituting
the relationship ap = kT;1-17 into Eq (4), a relationship
is obtained between the Debye temperature and the melting

was tested with a PMT-3 instrument. Loads of 20-200 g

hardness numbers do-pond on the load used, and this
relationship is beyond the limits of accuracy of the

(Ref 4) for relatively soft materials Ou, Za and Armco

67696
sov/126-8-4-19/22
Hardness and Brittleness of Metalloid Compounds
between microhardness numbeysand load for other metallic
and non-metallic materialsOwas established.
Gogoberidze et al note that the relationship
betveen microhardness mimber and load appears to be of a
general nature, as the apparatus for testing the micro-
hardness, even if specially regulated so as to indicate
microhardness numbers for a given material which are
independent of the load, nevertheless shows this
relationship in the investigation of harder materials.
However, other authors (Refs 97 10) insist that the
microhardness mi ber is independent of the load applied.
Investigations carried out in this work of the micro-
hardness of very hard materials have confirmed in all
cases the existence of a definite relationship between
microhardness numbers and load applied (Figs 1-1f). In
order to estimate the brittleness of metalloid compounds
a micro-brittleness method was used (having been first
suggested by Ikornikova, Ref 15) for the estimation of
Card the brittleness of carborundum,i!r The essence of this

estimating the number and nature of cracks and other
defects thereby arising. In order to lower the
subjectiveness if this estimation a so-called average
brittleness mark is introduced which is calculated
according to the degree of destruction shown by the
impression. The estimation of the degree of
destruction is carried out according to a 5-mark scale
(,,Joe Fig 5 and Table 1). Pigs 6 and 7 show the
dependence of the summary mark of destruction of
borides and silicides, respectively, on load. Table 2
shows the brittleness characteristics of metalloid
compounds. The authors arrive at the following
conclusionst The microhardness number depends on the
load at which the investigation is carried out. The
nature of the relationship between microhardness number
and load of materials with very great and comparatively
low hardness is identical and appears to be due to the
Card nature of plastic deformation of the surface of hard
3/7+ bodies In microhardness testing. The brittleness
characteristics of metalloid compounds obtained by the
microbrittleness methods in this work agree satisfactorily

TEXT: The conditions of obtaining..silicides--and borides of rare
metals are investigated and their physical properties are studied
for possible application. The.silicides.are.obtained by heating
the mixture- of ..the. component& - in -powdered form.at a pressure of
2.90 kg/cm2 and at a temperature of L300-21500C. The synthesis of
the borides is carried out by utilizing the interaction of metal
oxides with baroncarbide.and carbon in vacuum. The structure of
the obitained alloys- is.- investigated -and their. crystaL.structure is
determined.- The hexaborides are distinguished by their low work
