Abstract
A strong beta silicon carbide article is formed from a moldable mixture including beta silicon carbide particles, from about 1/16% by weight to no more than 1/4% by weight of the total weight of the moldable mixture of niobium carbide particles and a binder for supporting these particles for a molding operation. The mixture is molded to form the shape of an article, and the article is pyrolized so that volatile portions of the binder are driven off and the remaining portions broken down to a carbon phase. The carbon phase is transformed to beta silicon carbide in a siliciding operation. The addition of the small percentage of niobium carbide unexpectedly increases the strength of the finished beta silicon carbide article.
