ABSTRACT:
A process for producing a powder of .beta.-type silicon carbide, which comprises heating at a temperature of about 800.degree. to about 1,400.degree. C a mixture of a carbon powder having a particle size of about 20 microns or less and a metallic silicon powder with a carbon-to-silicon molar ratio of 1 : 0.6 to 1 : 2 in an oxidizing atmosphere having an oxygen concentration of 0.3 to 35% by volume, thereby to induce a spontaneous continuous reaction between carbon and silicon.
