Production process of silicon carbide short fibers

摘要

A process for producing silicon carbide short fibers comprises oxidizing metallic silicon powder in an oxidizing gas atmosphere into silicon monoxide in the form of ultrafine particles or gas, and carbonizing said silicon monoxide in a reducing gas atmosphere containing carbon at temperatures being lower than temperatures for producing powder and falling in a temperature range for causing a heterogenous core formation of silicon carbide, thereby producing silicon carbide short fibers. The process of the present invention is capable of mass-producing silicon carbide short fibers continuously in a short time.
