Abstract
In the production of SiC whisker for composite materials such as FRP, FRM, FRC and the like by vapor phase synthesis between silicon sulfide and carbon compound, SiC whisker suitable for the continuation and mass production is produced in industrial scale by using metallic Si as a starting material through a stage of contacting the metallic silicon with hydrogen sulfide gas to produce silicon sulfide gas, and a stage of contacting the silicon sulfide gas with carbon compound and, if necessary, a formed nucleus to deposit and grow whisker.
