Purpose of the development: Conducted research to obtain a new class of ultra-high temperature ceramic structural materials for use in the temperature range over 1600o C in a high-temperature oxidation, corrosion and erosion. The prospects of using the material for a wide range of high-temperature products of new technology in energy and other sectors of the economy. Increase range of operating temperatures (up to 1600-22000 C) and high-resource machines and units operating in hostile environment.

Recommended application field: Energy, machinery, processing of mineral raw materials (basalt).

Advantages over analogues: The economic effect is obtained by substantially increasing the operating temperature of CCD units, and hence the increase in fuel efficiency, increase service life and high reliability machines and units operating in hostile environment, the replacement of platinum in the feeders in the production of basalt fibers.

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: Ultra-high temperature ceramics, as well as the technology of its receipt does not have analogues in the world, some research ceramic zirconium diboride - Silicon Carbide being tested at the European Space Agency and the U.S..

Description of the development:
()
Development of this type of pottery in the world originated in the material specification nose cones and sharp edges of reusable space vehicles, the new gas turbine engine operating temperatures 1600-1700 C, as well as the requirements for the content of energy. Designed for today in the IPM NASU ultra-high temperature ceramic materials with high resistance to oxidation and corrosion is essentially of ceramic matrix composites based on the oxygen-free refractory compounds (borides, zirconium and hafnium - zirconium and molybdenum silicide - silicon carbide). To activate the process of sintering additives used some borides and carbides. Waste ceramics consolidation methods using hot pressing, hot pressing and reactive sintering without pressure (free sintering).
