ABSTRACT:
A process for the growth of silicon nitride whiskers consists of reacting a mixture of carbon and silicon dioxide powders at elevated temperature in a stream of nitrogen, said reaction mixture containing small amounts of metals such as chromium, magnesium, and nickel which promote the growth of silicon nitride whiskers by vapor phase transport. The whiskers obtained as a result of this invention are of much higher purity than those obtained by prior art.
