Functional and structural ceramics
based on fused silica, silicon nitride,
silicon carbide, aluminum oxide, zirconium dioxide, boron nitride and various compositions with the use of
ceramics
A group of materials working in the air at the temperature of up to 1400°C, in the inert atmosphere - at the temperature of up to 1800°C and in other gas atmospheres.
The materials possess the following characteristics:
high heat-shock resistance,
corrosion, erosion and moisture resistance,
hardness, controlled abrasion,
low friction coefficient,
high strength which is twice as large as that of steel, with the density being 40-60% lower than the density of steel,
high electrical resistance,
inertness to acids and alkalis,
resistance to Al, Mg, Zn, Pb and other melts.
A group of thermal insulation materials working within 300-1100°C and having the following characteristics:
low density and thermal conductivity,
heat-shock resistance,
ease of machining.
The technologies worked out by the State Research Centre make it possible:
to manufacture complex-shaped components from quartz ceramics, reaction-bonded, sintered and hot-pressed Si3N4, SiC,
to provide low shrinkage of the components made of reaction-bonded Si3N4,
to manufacture the components with the minimum deviation from the given geometrical parameters and suitable for machining.
