COMPOSITION FOR PRODUCING OF CERAMIC MATERIAL Russian patent published in 2005 - IPC

Abstract RU 2243954 C2

FIELD: powder metallurgy, in particular ceramic material composition.

SUBSTANCE: claimed composition contains (mass %) boron nitride 10-20; silicium carbide 73.5-82; titanium 3-7; silicium 0.1-1. Composition is obtained by blending and subsequent plasticizing with organic binder. Composition is useful as refractory materials for high temperature furnaces and chemical reactors. Articles from composition of invention are produced by hot pressing and have heat capacity of 577-601 J/kg⁰C at 25⁰C, thermal conductance of 6.4-8.0 W/m.K at 400⁰C, thermal-shock resistance of 25-29 heating cycles up to 1400⁰C followed by cooling with water at 20⁰C.

EFFECT: materials with improved bending strength and hardness.
