POWDERY SILICON CARBIDE COMPOSITION FOR SINTERING |
摘要 |
<p>A sintered silicon carbide body having a high thermal conductivity and a high electrical insulation without any drop substantially throughout the sintered body is produced from a powdery silicon carbide composition comprising at least 90% by weight of silicon carbide powders having an average particle size of not more than 10 .mu.m and 0.01 to 4% by weight of powders of beryllium or its compound having a particle size of not more than 30 .mu.m in terms of beryllium atom, a nitrogen content of the composition being not more than 500 ppm.</p> |
