SPHERICAL SILICON CARBIDE POWDER, PROCESS FOR PRODUCTION OF SAME, AND PROCESS FOR PRODUCTION OF SILICON CARBIDE CERAMIC MOLDED ARTICLE UTILIZING SAME

摘要

Disclosed are: a spherical silicon carbide powder; and a process for producing a silicon carbide ceramic molded article using the spherical silicon carbide powder. A high-purity spherical silicon carbide powder can be produced by decomposing a spherical cured silicon powder by heating under a non-oxidative atmosphere. In the process, a spherical cured silicon powder is used as a starting raw material. Therefore, a desired spherical silicon carbide powder can be produced readily only by the thermal decomposition of the spherical cured silicon powder.
