COMPOSITION FOR MANUFACTURING
Yu. A. Aleksandrov, E. I. Tsyganova, V. M. Shekunova,
and I. I. Didenkulova
Patent RU 2345973
IPC C04B 38/02
1. A composition for manufacturing heat-resistant ce
ramic material that includes a phosphate binder, clay body,
foaming agent, modifier addition agent, and water that is dis-
tinguished by the fact that it contains these components in
the following quantities: clay body, 8.0 – 40.0 wt.%; phos-
phate binder, 20.0 – 48.0 wt.%; foaming agent, 0.10 – 0.35 wt.%;
modifying additon agent, 0.24 – 40.0 wt.%; water, 0 – 5.0 wt.%.
Finely hammered PGSOA clay (8.0 – 20.0 wt.%) and (or)
fireclay mortar (0 – 20.0 wt.%) and (or) chromium mortar
(0 – 11.0 wt.%) is used as the clay body with orthophospho-
ric acid and (or) aluminoborophosphate binder serving as the
phosphate binder, PAP brand aluminum parting dust as the
foaming agent, and at least one of the following as modifying
addition agents: alumina-rich cement (0 – 12.0 wt.%), Fe
(0. – 6.0 wt.%), corundum (0 – 22.4 wt.%), calcium oxide
(0 – 1.7 wt.%), aluminum hydroxide (0 – 0.1 wt.%), and car
bon black (0 – 4.0 wt.%).
2. The composition of Sec. 1 is distinguished by the fact
that the clay is not subjected to preliminary roasting

CERAMIC PROPANT WITH LOW DENSITY
AND A METHOD OF PREPARATION
OF THE COMPOUND
Z. Yu. Usova and E. M. Pershikova
Patent RU 2346910
IPC C04B 35/16
1. Ceramic propant with low density, consisting of a
light aggregate and a binder of ceramic material is distin
guished by the fact that vermiculite, pearlite, hydromicas,
natural zeolites, agglomerated coral, and claydite are used as
the light aggregate.
2. Propant of Sec. 1 is distinguished by the fact that the
mass fraction of the light aggregate in the propant granule is
not more than 80 wt.%.
3. Propant of Sec. 1 is distinguished by the fact that the
light aggregate is covered by an organic or inorganic coating
prior to addition to the raw mixture.
4. Propant of Sec. 1 is distinguished by the fact that the
clay, kaolines, and bauxite, or composites of these substances
are used as the binder material.
5. Propant of Sec. 1 is distinguished by the fact that the
aluminum oxide, metallurgical slag, phenyl-formaldehyte
resin, aluminum, and bronze or composites of these sub-
stances are additionally added to the binder material.
6. The method used to produce propant, which includes
preliminary grinding and blending of the initial components
with subsequent pelletization of the components, drying, and
sifting into integral fractions, is distinguished by the fact
that, at the least, ceramic binder material and a light aggre
gate are used as the inital components, moreover, that
vermiculte, pearlite, hydromicas, natural zeolites, agglomer
ated coral, and claydite are used as the light aggregate.
7. The method of Sec. 6 is distinguished by the fact that
roasting of the light aggregate, accompanied by a change in
volume, is performed prior to the blending stage.

REFRACTORY BODY FOR LINING
OF POWER UNITS
R. R. Nazamov, I. R. Mokhnyak, N. V. Nizamova,
and Yu. D. Semykin
Patent RU 2347765
IPC C04B 35/10
A refractory body for use in the lining of power units that
includes boric acid, chromium oxide, and synthetic corun
dum that is distinguished by the fact that magnesite is addi
tional aded to the composition, and with the following ratios
