ABSTRACT:
This disclosure teaches a method of making a silicon carbide article of less than full density. A mixture of silicon carbide particles, silicon particles and a thermosetting polymeric material are molded to form an article as a green body. The green body is pyrolyzed to change the polymer into carbon and the carbon is then changed into silicon carbide by the silicon contained in the mixture.
