ABSTRACT:
A sinterable silicon carbide mixture is described which is prepared by mixing finely-divided silicon carbide containing between about 0.5 and about 5.0 percent by weight of excess carbon with a finely-divided beryllium-containing additive wherein the amount of beryllium in the mixture is equal to between about 0.03 and about 1.5 percent by weight of the powder. A dense silicon carbide ceramic product is prepared from the powder mixture by pressureless sintering wherein the article is initially shaped and subsequently sintered in a beryllium-containing atmosphere at a temperature from about 1950.degree. to about 2300.degree. C.
