a. The Buna Plant in 6chkopau is assigned to the Kaustik
.ioviet Corporation and its production is partly combined in
the Leuna Picat schedule. Part of the plant was dismantled
in June. 1948. The following official 1949 prodwtion plan
provides for an annual buns pt.oduction of 27,000 tons. This
estimate is exagferated and w111 probably not be reached due
to the dismantling At present,the plant has the following estimated

2r9v s;Lonal Retort on 41Te,riments to Improve -.9 eualities of
tures
21.1uminum Oxide as Act ve Wh te itrent n Ru er-
----I, a
The eurpose of this -provisional rerort is to acluaint the
technical personnel of the plant with the results of exper.
:nefts made to find an improved aluminum oxide composition to
be used as active Main- arent hesearch activities are not
corepleted but the results achieved so far can be used as a
basic method in the manufacturinp procedure.
The first patent for the use of aluminum oxide as filling agent
as applied for in 1941 by the Deutsche Gold- un d edlberscholde-
anstalt Firm. In this application aluminum oxide was mentioned
as highly active fliling agent for natural and synthetic rubber0
Ely using aluminum oxide as the filling agent the tensile strength
of butadienerubber is increased to 208 kg/cm2 and the strength
limit is 462 percent.
In tests by Jr. Lelles and Die ilauschulz in the Luna plant
and tests by Jr, Pattok in the 2arbenfabri1 Tablfen, the ad-
dition of aluminum oxide (obtained from alum or aluminum eul-
phete) indicates an excessive degree of defornat1on (10,000
to 20,000 or more) although the soligity of the vulcanized
meterial is increased (200-2/30 kg/cm-)0
leabber mixtures with such a high deformation depree cannot be
processed in rubber plants. Therefore the industrial use of
aluminum oxide as an active filling agent was not practicable
in the form proposed by the Deutsche Gold- und oilberecheide-
anstelt
The value of eluminam oxide as filling material is also con-
siderably reduced due to its excessive static stretch dilation
(40 to 80 percent).
Dr, Hellos and Dr. Lauschulz made seecial tests to obtain
aluminum oxide with a normal rate of mixture deforezation0
email quantities of inorganic salts of alkali-metals and
other :letals were added to the sulphate before the beatine
process, The tests had no practical results. Illthoueh the
decree of deformation declined,the tensile strength of the
vulcanized material decreased .considerably.
5. It is probable that the addition of alkali-salts at a heat-
ing temperature of 9000 to 1,0000Cleads to the formation of
nonactivo meltines with aluminum oxide or favors sintering of
aluminum oxide particles due to their size or share or the
condition of the surface, thus producing nonactive forms.
exe Espich tried to solve the ?nroblen of the low degree of
dellormation by the same procedure, Aie also added various
Inorganic salts to the basic wew material before heatine.
However, his tests did not lead to any positive results
either,
The following data were listed in the experiments of Dr.

Summarizing the mentioned tests aluminum
oxide is not suitable as a filling agent in the proposed
form, Hoveirer, the research is sipnificant as it proves
for the finet tiro, that the tensile strength of vulcanized
material Is considerably increased by adding to the rubbeA:
mixture aluminum oxide obtained from alum or aluminum sul-
phate through disintegration at high temperature. Aluminum
oxide can be used as active filling ogent in the rubber in-
dustry only after the problem of reducing the degree of de-
formation to a normal figure (1,500 to 3,000) has been solved.

The results results .show that by pereent.of paraffinic acid
only a decrease o4. the degree of deformation occurred.
?hu addition of paviffinic acid in greater quantities leads to,
a reduction of the degree of deformation and to a reduction
01' the tensile strength of vulcanized material (see table 3).
This method was abandoned due to unsatisfactory results,
b. The second met'aod consisted in covering the surface of the
aluminum oxide with the layer of organic matter to decrease the
friction between rubber and filling agent. thus reducing the
degree of raw deformation. This represents an absolutely new
procedure in the rubber industry.
ehile examinin silipur as an active filling agent* obtained
through precipitation of silikosol sulphate by moans of an
ammoniacal. solution of sodium sulphate, Dr. Pattok tried
various materials to increase the moistening property of the
filling agent in tAe rubber compound. The following materials
were tested:
T.G. wet, chloric rubber, styrol, raw rubber,I,G, wax N (new)
and benzyl cellulose. These materials were first dissolved in
water or benzol and in this condition coated on the surface of
the filling agent. As shown by the table below the used ma-
terials not only reduced the degree of solidity but also in-
creased the decree of the deformation of the ray mixtures.

1?inal conclusions
.additions of 2 to 3 percent of paraffinic acid increase the
solidity up to 250 kg/cm2; they improve the ductility
decrease plasticity,and.slightly reduce the decree or de7
formktion.
After addition of 5 percent of paraffinic acid the tensile
strength ?decreases, the ductility improves, and the-, .
degree of deformation declines considerably but not enouch.
3.
further addition of paraffinic acid nroduces a sharp decline
of the solidity of the vulcanized material. The degree of
deforMation remains normal.
. The second test series investigated the treatnent of aluminum
oxide with actents to imnrove the mixing nronerties of the
filling agent with rubber. Those tests were based on the fol-
lowing procedure:

9. Conclusions of Abovelisted Tests
a. The processing of aluminum oxide with various agents diminishes
friction between rubber particles and the oxide surface
produces a filling agent riving rubber a high rate of solidity
(280-300 kg/cm), and tensile strength (000-750 percent) and,
simultaneously, reduces the decree of deformation (from
200,000 up to norm). values).
b. All tested materials can be divided into three croups.
(1) The first group of admixtures lowers both the deformation
degree and the solidity of vulcanized natters. This group
is comprised of emulgator E-1000 and. sapel.
(2) The second group of admixtures lowers the defo degree
but retains the tensile strength. This group is comprised
of merSolates and paraffinic acids.
(3) The third group at admixtures lowers the defo degree
at the same time increasing moderately or strongly the
solidity. This group is comprised of seral, iron-
naphtate, sodium-resinate, etc,

c. It is characteristic of all three croups that they lower
the defo-degse to normal figures and considerably increase
the ductility, sometimes up to. 34,100 percent (see '
tests with benzol-sulfonic acid).
d. The use of all these admixtures usually reduces the
elasticity. eveLLadS eaeo heee-feee te eelvo
_this problem also, either by adding smaller quantities of
aluminum oxide to the rubber compound or by using special
arents for retaining the elasticity (see table 6).
10. a. This research is important because it proves aluminum
oxide to be a high quality Milne agent for rubber com-
pounds and also helped to considerably simplify production
methods and find a furnace design for aluminum oxide
production. aluminum oxide was produeed in a test cupola
furnace with exterior heating in the Luna Plant. This kind
of furnace cannot be considered a model type of an in-
dustrial furnace. eiuffle-furnaces used for aluminum oxide
production in 'aolfen and EitterfeId are also not model
furnace types if the volume of aluminum oxide and the im-
portance of this valuable filling agent for future pro-
duction is considered.
At present perfect furnace types are the modern dram rotary
furnaces with exterior and interior heating and cupola fur-
naces with interior heating. The furnaces have a high prow
duction caracity and can be 'pe rated continuously.
b. A rotary experimental furnace for aluminum oxide production
was tested in the Polysius Plant in Dessau in June 1948. The
furnace was 8 meters long and 30 to 40 cram diameter.
aluminue sulphate was introduced at one end of the drum
while the burner head was arranged at the other end. The
test showed that the whole active part escaped in the smoke
due to the great volatility of aluminum oxide. The part
of aluminum oxide which reached the onposite end of the
furnace was nonactive. This installation was not usable
as separation of a volatile material such as aluminum
oxide in gases heated to l000?C is very difficult and
reluires a very complicated plant with various systems of
cyclone filters, etc..,
c. Uupola furnaces with interior heating olariously have the
sale defects. Dr. oll proposed a noteworthy furnace con-
struction for our aluminum oxide production departnent. He
suggested the insertion of a thermax pipe of seell diameter
into a conventional rotary furnace. The heating gases cover
the outside+ of the the rmax pipe with aluminum sulphate and
aluminum oxide insides while pipe and furnace revolve.
However, such a furnace cannot be rerarded as a model type
as there is a critical shortage of thermax material. The
solidity of thermac also rapidly declines at temperatures of
1,000 to 2s000?C.
d. The tests proved normal rotary furnaces without thermax
or cupola furnaces with interior heating as the most suitable
types for the aluminum oxide production. The aluminum oxide
is seearated from the heating rases by wetting with water
or a mild soda solution or other liquids. Experiments of
this kind are presently done by Engineer Khycheyan and
Dr. ,lean.
