Purpose of the development: The development is designed to produce industrially attractive technical ceramics with improved physical and technological parameters.

Recommended application field: Manufacture of special-purpose machinery.

Technical characteristic: - the average size of the output powder reagents obtained from industrial precursors by the method of mechanochemical activation - from 20 to 200 nm; - relative density - from 40 to 95% (set by the temperature-time mode of sintering); - melting point - from 850 to 2100 ° C.

Advantages over analogues: - high resistance to high-temperature oxidation; - acceptable values of coefficients of thermal expansion and adhesion; - the use of industrial precursors to produce the original nanopowders.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
New approaches have been developed in the methods for the production of ceramic materials with a spinel structure for: - adhesion compounds of corundum armored ceramics plates with plates of ferrite absorbers of electromagnetic radiation; - coatings for ferritic chrome steel switching elements in assemblies of fuel cells with solid-state electrolyte; - coatings with a high emissivity (at least 88%) in the temperature range of 550-1100 ° C, which are suitable for operation in high vacuum conditions (reflectors of nuclear power generators, radiators, radiators for space vehicles, etc.); - inert matrices for the isolation of radiation waste.
