Ceramic composition suited to be injection molded and sintered

A sinterable ceramic composition suited to be injection molded and substantially sintered at temperatures between about 1900.degree. and about 2200.degree. C. consisting of:

• (a) from about 65 to about 90 percent by weight of particulate silicon carbide,
• (b) from about 12 to about 18 percent by weight of thermoplastic resin having a volatilization temperature between about 200.degree. C. and about 500.degree. C.
• (c) from about 2 to about 8 percent by weight of an oil or wax having a lower volatilizing temperature than said resin, and
• (d) from about 0.3 to about 5.0 percent by weight, based upon the weight of said silicon carbide, of boron or beryllium, or mixtures thereof as a sintering aid, and
• (e) from about 0.1 to about 3.0 percent by weight of an organo-titanate selected from the group consisting of tetra (2-ethylhexyl) titanate;
• isopropyl, triisosteroyl titanate;
• tetraisopropyl, di(tridecylphosito) titanate;
• titanium di(dioctylphosphate) oxacetate;
• titanium di(dioctylpyrophosphate) oxyacetate;
• isopropyl, isostearoyldiacryl titanate;
• isopropyl, tri(dioctylphosphate) titanate;
• isopropyl, tri(dioctylpyrophosphate) titanate;
• tetraisopropyl, di(dioctylphosphito) titanate, di(dioctylphosphato) ethylene titanate, or mixtures thereof.
