Abstract

A desired shape is formed from a polysilane having the average formula {(CH3)2Si}{CH3Si} and the shape is heated in an inert atmosphere or under vacuum to 1150-1600 DEG C until the polysilane is converted to silicon carbide. The polysilane contains from 0 to 60 mole percent of (CH3)2Si = units and from 400 to 100 mole percent of CH3Si IDENTICAL units. The remaining bonds on silicon are attached to another silicon atom or to a chlorine or bromine atom, such that the polysilane contains from 10 to 43 weight percent of hydrolyzable chlorine or from 21 to 63 weight percent of hydrolyzable bromine.
