METHOD OF PREPARING BLEND FOR MOLDINGS CONTAINING SILICON CARBIDE Russian patent published in 1997 - IPC

FIELD: constructional materials. SUBSTANCE: method consists in mixing carbon-containing ingredient, filler, and temporary binder, the first of which being thermally expanded graphite powder which has been preliminarily modified by way of compressing into briquets with density 0.25-1.15 g/cu.cm and subsequently ground into powder. This powder is applied in amount exceeding 100/(2ρ₁/(ρ₂+1) wt % where ρ₁ is filler density and ρ₂ density of thermally expanded graphite. EFFECT: diversified carbon carbide-based materials prepared with improved structure and mechanical properties.
