Results in research and development of structural ceramics (high-temperature ceramic monolithic and com
posite materials based on high-melting nitrides, carbides, and oxides (Si
, BN, SiC, Al
wollastonite) are reported from the Tekhnologiya Research and Production Enterprise. Superior properties of
the materials are emphasized.
The Research and Development (R&D) Center “Struc
tural ceramic materials, constructions, fabrication techno-
logy, and operational reliability management of thermally
stressed ceramic components” set up at the Tekhnologiya Re-
search and Production Enterprise and currently headed by
Academician A. G. Romashin has gained general acceptance
within the relevant scientific communities both at home and
abroad [1 – 3].
Researchers and engineers at the R&D Center have made
a significant contribution to the theoretical and experimental
study of new ceramic materials intended for structural engi-
neering applications. Scientific foundations for the design of
thermally stressed components made up from brittle materi
als have been laid. New standard engineering solutions and
design principles have been formulated, and programs for
thermal strength analysis and integrated operational reliabi
lity management have been developed within the conceptual
scheme material – properties – numerical analysis – struc
ture – technology – trial tests (Fig. 1).
A unique research and production base in Russia and,
perhaps, over the world has been set up equipped with ad
vanced facilities (high-temperature furnaces operating at
1700 – 2200°C under vacuum and 1750°C in air, vacuum-
compression furnace, hot-pressing units, a hydrodynamic
pressing machine, gas and tunnel furnaces, mechanical test
ing machines operating at 1600°C in air and 2000°C under
vacuum and in an inert medium).
A total of 30 structural ceramic materials based on sili
con carbide and nitride, alumina and zirconia, and boron
nitride and aluminum titanate with controlled microstructure
and tailored properties for operation in the temperature
range of 1500 – 1800°C, in conformance with international
standards on mechanical, thermophysical, and tribological
characteristics and resistance to aggressive media, have been
developed. The materials and technologies for their prepara-
tion have been supported by patents and have found applica-
