Abstract
BERYLLIUM CONTAINING SILICON CARBINE POWDER COMPOSITION Disclosure is made of a suitable silicon carbide mixture which is prepared by mixture finely divided silicon carbide containing between about 0.5 and about 5.0 per cent by weight of excess carbon with a finely divided beryllium containing additive wherein the amount of beryllium in the mixture is equal in between about 0.03 to about 3.0 per cent by weight of the powder. A dense silicon carbide ceramic product may be prepared from the powder mixture by either but pressing the mixture at temperatures of between about 1900.degree. and about 2200.degree. C. at a pressure between about 1,000 to about 10.000 psi or by pressureless sintering wherein the article is imitially shaped and subsequently sintered at a temperature from about 1950.degree. to about 2300.degree. C.
