ABSTRACT: The production of beryllium in the USSR is carried out by the
following methods:
1) Electrolysis of Na 2BeF4 or of a mixture of 2BeO.5BeF 2
with barium fluoride. The beryllium obtained is not of high
value either quantitatively or qualitatively.-
2) Electrolysis of a mixture of molten beryllium and sodium
chlorides. By this method Be with the following impurities
is obtained:
Fe 0.01 to 0.02 % Cu 0.02 to 0.07 %
Mn O@001 % Si 0.01 %
Card 1/5 Ni 0-02 to 0.05 % Cr< 0.003 %

Beryllium
Card 2/5
SOV/89-5-6-3/25
3) Reduction of beryllium fluoride with metallic magnesium.
The purity of the beryllium produced in this manner is
characterized by the following impurities:
Fe 0.08 to 0.10 % Mn 0.01 to 0.02 %
Al 0.02 to O.D3 % Cu 0-003 to 0-005
Si 0.01 to-0.03 % Ni 0,003 to 0.005
4) Vacuum di6tillation.
The beryllium produced in this manner is the purest of all
and contains only the f6llowing impuritiesi
Fe 0.005 %
Al 0.003 %
Cu 0,004 %
Ni 0.003 %
Cr 0.005 %
Mn 0.002 %
The production of metal-ceramic singlu parts is characterized
by the following methods and parameters:
a) By Vacuum hard-pressing (10- 2to 10-3 torr) it in possible
to produce large single parts or parts having a maximum
density of 1-85 g/cM3 and being of fine-grained structure as

Beryllium
SOV/89-5-6-3/25
well as having mechanical properties that are equal in all
direAions. At 1120-11500 C the amount of pressure applied
2
amounts to from 50 to 30 kg1cm
b) Hot-pressing in air requires increased pressure values
2
of from 100 to 150 kg/cm
c) For the production of single parts of great density and
strength hot-pressing is carried out in metal press molds in
air at from 550 to 6000 C and at a pressure of 4-5 t/cm 2.
d) Production of single parts with a density of from 1.75
to 1.82 &/CM3: Beryllium powder is pressed with 10-15 t/cm
pressure, annealed in a vacuum at 1180-12000 C, and is then
subjected to subsequent treatment at normal temperature and
a pressure of 10-15 t/cm2 or at 500-5500 C and at a pressure
2
of 8-10 t/cm
The properties of beryllium vary within a large domain in
aependence on purity and structure (according to B. A. Sidorov
and M. I. Stepanov, collaborators at the laboratory of
Card 3/5 N. IT. Davidenkov). The results obtained by means of mechanical

SOV/89-5-6-3/25
investigations show that the latter depend to a considerable
extent on processing and on the condition of the surface.
Beryllium parts are easy to grind. The refractoriness of
beryllium in air is very high. After annealing for several
hundred hours at 5000 C it does not decay. At 10000 C. however,
the surface begins to be covered with a thick and soft oxide
layer already after one hour. The stability of beryllium with
respect to water is quite satisfactory. Technical beryllium
contains various inclusions also after the first vacuum-casting,
which, above all, cause the leakage of gas. In order to avoid
this it is advisable to combine vacuum-casting with simultaneous
centrifuging (Ye. S. Ivanov, V. M. Shmelev).
A crucible of beryllium oxide is evacuated up to 1.10-4 torr
after having been filled with pieces of beryllium and closed
by means of a beryllium-oxide stopper. The crucible is heated,
to a temperature of 600-9000 C. The furnace is filled now with
argon (30-50 torr) and the metal is heated to a temperature of
1450-14700. The crucible is kept at this temperature for five
minutes, after which its contents is emptied into a rotating
Card J/5 graphite mold. The single beryllium parts produced in this
