Abstract

The invention encompasses a method of forming a composition containing an AlN-SiC composite and/or solid solution, the method comprising: a) combining sources of silicon nitride, aluminum, and carbon to form a mixture, and b) heating the mixture whereby the sources react to form an AlN-SiC composite and/or solid solution. The mixture may be shaped before the reacting step. Also, the reacted mixture may be further heated to produce a densified body.
