摘要：
A fine &bgr;-silicon carbide powder is prepared by impregnating graphite with an organosilicon compound selected from crosslinkable silanes and siloxanes, causing the organosilicon compound to crosslink within the graphite, and heating at 1,300° C. or higher in an inert gas stream for reaction. Using only low-temperature heat treatment in air and high-temperature heat treatment in inert gas, the invention enables industrial, economical manufacture of fine silicon carbide powder in a stable manner.
