Abstract
Precursor materials and methods of making are disclosed. The precursor materials include at least one of a silica source, and a carbon source, with or without liquid and a binder The methods described include pyrolyzing the precursor material to form a carbonaceous mixture and heat treating the mixture for a pre-determined time and at an elevated temperature during which carbon and/or nitrogen react with silica in the mixture to form carbides and/or nitrides. The carbides and nitrides formed from said methods may be used as blowing agents in a glass, ceramic, or metal forming processes or for promoting dispersion of the carbides and nitrides throughout a glass, ceramic, or metal composite.
