Abstract
A method of forming a silicon carbide ceramic material without forming large areas of a feathered alpha silicon carbide microstructure is disclosed. Basically, the method involves heating the silicon carbide material to a temperature in a range from about 1850.degree. C. to about 1920.degree. C., preferably about 1900.degree. C., and maintaining the material at the selected temperature for a period of time from about 6 hours to about 12 hours. Such a heating cycle produces silicon carbide ceramic material which does not have large areas of a feathered alpha silicon carbide microstructure therein.
