Abstract
PURPOSE:To produce the title silicon carbide whiskers at a low temp. in a short time by heating a mixture of solid silicon and solid carbon in a carrier gas current, and keeping the mixture at that temp. CONSTITUTION:The powdery solid silicon selected from amorphous silicon, a silicon single crystal, a silicon polycrystal, etc., and the solid carbon such as carbon powder and a graphite sheet are uniformly mixed. The mixture is heated at about 800-1,300 deg.C in the current of a carrier gas such as argon, kept at that temp., and then air-cooled. As a result, white silicon carbide whiskers are formed on the surface of the mixture. Since the reaction temp. is low, the SiC powder due to the direct reaction of solid silicon and solid carbon is not formed.
