Abstract
SiC whiskers were obtained from the porous bodies produced from polymerizable W/O-type emulsions containing polycarbosilane and milled carbon fibers by the heat treatment at 1273 to 1623K in Ar. The whiskers were deposited on the surface and inside of the porous bodies. The whiskers were found to be β-type SiC whiskers by X-ray diffraction analysis. The whiskers obtained by the heat treatment at 1623K had diameters from 0.2 to 0.6μm and lengths from 10 to 50μm. Scanning electron microscopic analysis revealed that SiC whiskers grew by the vapor-liquid-solid (VLS) process.
