Abstract
A new method for preparing ultrafine powder of SiC is proposed. A carbon rod is mounted vertically with a block of silicon at the bottom of the system. The apparatus is held in rarefied inert gas and heated by an electric current. The SiC produced by the heating then evaporates forming a smoke, the particles of which are β–SiC <100 nm in diam.Keywords
