Carbonaceous ceramic composite for use in contact with molten nonferrous metal

Abstract

This invention provides a carbon-containing ceramic composite for molten non-ferrous metal, the composite being a sintered ceramic body to be used in contact with molten non-ferrous metal, the sintered body containing an aggregate of silicon carbide and/or silicone nitride, the sintered body being characterized in that it comprises, (a) 100 parts by weight of the aggregate, (b) 5 to 45 parts by weight of flake graphite, and (c) boron carbide in an amount of 10 to 40% by weight based on the flake graphite.
