Ceramic composite structural materials
Reaction-bonded silicon carbide
The Institute manufactures and supplies the high-quality details made from technical ceramics, resistant to oil, and sea water:
• Sealing ring for pumps, the transfer aggressive liquids, including oil;
• Sealing ring for compressors and mixers;
• Bearings and beam cartridges.
Resource of silicon carbide pieces in friction pairs of different application exceeds similar one at products made from siliconized graphite by 3-5 times at comparable prices.

Ceramic composite material based on the hexagonal boron nitride brand «БГП-10» is receiving by hot pressing method in graphite forms. It is notable for excellent machining tooling, chemical and corrosion resistance to gas environments and metals melting (aluminum, high-alloyed steel). Implemented as a material for discharge chamber of stationary plasma engines in space vehicles.
