ABSTRACT:
Disclosed is a process for producing silicon carbide whisker by mixing a silicon source with carbon black and subjecting the resultant mixture to heating treatment in an inert atmosphere, which comprises using a silica recovered from geothermal hot water as said silicon source.
The process of the present invention has the advantages of (1) being capable of producing SiC whiskers with slender diameters and small variance of lengths, and (2) contributing to effective utilization of resources by utilizing the silica recovered from geothermal hot water as the silicon source, etc. and its industrial value is great as the method for providing SiC whisker reinforcing material for various kinds of composite materials.
