TITLE: Production and Some Properties of Hafnium Boride
PERIODICAL: Tsvetnyye metally, 1959, Nr 11, pp 48-50 (USSR)
ABSTRACT: Considerable work has been carried out on titanium and
zirconium borides. Little study has been made of
hafnium boride, but preliminary investigations show
it has even better properties. There is probably
only one stable compound - the diboride with AlB2 type
structure. It has been obtained by precipitation from
the gas phase (Ref. 2.3). In the present work it was
produced by the reduction of hafnium oxide by boron or
boron carbide in a vacuum furnace. The relation of
the free energy with temperature is -
6 F 358.2 x 103 - 175-05T
& F 91.9 x 103 - 39.1T
for reduction by boron carbide and boron respectively.
The reduction with carbide takes Dla-ce at somewhat

showed it was the stoichometric diboride. X-ray
analysis showed the cell to be a =-3.137 and c = 3.469
agreeing with the 1~terature. Hot Dressing was
carried o~t-at 20'50 for 5 minutes with a load of
150 kg/cm . The minimum porosity obtained was 15.1%.
The electrical resistance of the compound was 8.8 micro
ohm/cm agreeing with the literature when porosiq is
Uaken intg account. The microhardness was 2920-
500 kg/mm . At temperatures above 650 to 700 C,an
oxide film was formed on the compound. There are
15 reference.s, of which 9 are Soviet, 5 English and
1 German.

LBSTRACT: Hitherto, the compounds of nearly all rare-earth metals with
boron, with the exception of promethium, terbium, and
thulium, are known and have been sufficiently well investigated.
Among them, the compounds of terbium with boron are of special
interest because of the 2 possible variants of the electron
structure of the terbium atom (which are described by the
8 1 2 2
configurations 4f 5d 6s or 4f96 3 ). The terbium- and boron
compounds were produced by the reduction of terbium oxide by

took 1 hour at 1650 , The reduction with boron resulted in a
blue-colored product, and its X-ray picture is characteristic
of the hexaborides of the rare-earth metals with cubic
I
lattice of the structural type 0 h . According to the results
obtained by calculating the intensities of X-ray reflections,
this product was found to be terbium-hexaboride with the
t
lattice period a = 4-11 A. Reduction of the te-bium oxide
by boron carbide gave a greyish-brown product, viz TbB

with the identity periods a = 7~13 A and c = 4.07 A of the
tetragonal lattice. The work function of the electrons in the
thermoemission from TbB6 is f- 3.1 ev and was determined by
V. A. Trigubenko and B. M. Tsarev. This value corresponds
to the dependence of the work function of the borides on the
ordinal number of the rare-earth metals, which had been

two structures, the last-mentioned is uniquely confirmed.
The existence of the fsd - electron configuration indicates
a considerable degree of binding of the electrons of terbium
and boron in the sd-band of the hexaboride lattice. The
existence of the borides TbB 4 and TbB6 and their
crystallo-chemical characteristics were for the first time
determined by the authors. There are 2 tables and Do

ABSTRACT: The authors report measurements of the emissivities of
'~orides 0q3_rbj ']of refractory
powders of Aeskland nitride k
and rare-earth metals. Measurements were carried out with
an instrument shown in a figure on p 1~10. This instrument
simulated closely an absolute black body. A tantalum
cylinder 5 (20 mm diameter, 50 mm height) served as a
heater. Inside the cylinder 5 there was another smaller
tantalum cylinder 6 (8 mm diameter, 20 mm height) which
was placed concentrically with the cylinder 5. In each of
the cylinders there was a small aperture and these
apertures were aligned horizontally. The lower ends of
the two tantalum cylinders were fixed to a molybdenum
plate 4 which was pressed against the cylinder 5 by a
Card spring. The whole instrument was enclosed in a.glass
1/2 bulb 1. The inner cylinder 6 was coated with 100 ji thick
layer of paste prepared from a fine powder (particles of

using the following formulas

TEXT- The authors synthesized SrB6 by the reactions SrO+B4P+2B=Sr%+CO (I)
and SrO +7B =SrB6 +(BO) (II). Initial substances were SrO obtained by
heating 96.37 ~o Sr C03 to 12500C, B4C, and 98.4 % B. The composition of
briquetted charges corresponded to the reaction equations. They were
heated to 1000-20000C for 1 hr each. Then, their composition was
analytically determined. Heating was conducted in an electric vacuum
furnace. The pressure in the furnace was determined according to
G. V. Samsonov (Ukr. khim. zhurn,, 23, 287 (1957)). Reaction I showed a
Dressure increase at 12500C caused 7y SrO reduction in which Sr evaporated.
In the range of 1000-12000C the reaation proceeds very slowly. In the
range of 1500-17000C, the SrB 6 yield was only 60-70 % due to evaporation

of Sr. In the range of 1800-20000C, SrB 6 formed so rapidly that Sr did
not volatilize. The yield increased to 87 %. Since reaction I yielded no
carbon-free product (0.,44 % 0 at 20000C), reactiop 11 was studied. Here,
a minimun yield of SrB6 (62.9 %) was observed at 16000C due to rapid
evaporation of Sr and B. Maximum yield (75.4 %) was obtained at 18000C,
the product being free from C. The following physicochemical data are
mentioned., Heat of formation of SrB6 =50.4 kcal/mole; radiation
coefficient =0.79 at X =0.655 mp between 800 and 18000C. Between 1400 and
21000C, vapor pressure follows the equation; log p,. -6,43 -21423/T.
Therefrom, the boiling point of SrB6 is calculated to be 540000. Heat of
sublimation was found to be 97.2 kcal/mole, For samples pressed at
21000C and 150 kg/CM2 (residual porosity about 10 %), the following data
were found; Electrical resistivity -191.8 pohm-cm (referred to material
free from pores), microhardness= 2900 :90 kg/mm2. L. Ya. Markovskiy~s

studied have mainly a metallic type of conduction. A tendency of the resistivity to
decrease with increasing B/Cr ratio was observed. In all cases, there is a certain
deviation of the temperature dependence of the resistivity from linearity. A correla-
ion was established between the nature of the change in melting point and the magni-
tude of resistivity. The coefficient of thermal expansion decreases in regular fash-
tion as the B/Cr ratio increases. The relationships established are satisfactorily ac-

Accelerated plasticisation (20 - 30%) was obtained with
bis (para-tert.-butylohenol) disulphide. Results (at a
temperature of 500 - 600C) are given in a Table. The
effect of the temperature of processing on the plastici-
sation of natural rubber in the temDerature limits of
500 - 1200C was investigated. The plasticity (according
Uo Karrer) was decreased on increasing the temperature,
but in all cases the plasticity of natural rubber con-
tainin- the above named substances was higher than that
of untreated natural rubber. A maxi?mim degree of
tjlasticisation of natural rubber was obtained winen the
rubber was first heaued before being fed to the rollers
(1000C) and when processing was carried out at 500-550C,%
Tihis was verified on a rubber mixer in the Sverdlovsk

ABSTRACT An electrod,,rna-mic current stabilizer for use in industrial
i-orocesses is described. The device is a current transformer vith a
fixed primary and a movable secondary solenoid on a cylindrical core.
iThe core is set- at a desired anf,,le to the horizontal in such a manne.-
that t1le secondary's gravity force is balanced by the primary's
reDulsive -force and the secondary finds a rest position. Any chan,-.~
in inz)ut volta-e or imredance causes a corrective repositioning of the
secondary -for rebalance. It, can be shown however t'nat the secondar-...r
current rem'-ins constant as a function of angle over a wide ranE;e of
in,out voltage variation. Ex-oeriments showr that secondary currents -will
