ABSTRACT:
High surface area open microporous, partially crystalline, partially amorphous, solid ceramic materials containing silicon carbide with or without silica with or without carbon may be prepared by controlled pyrolysis of (RSiO.sub.1.5).sub.n gels in an inert atmosphere. The silica and carbon content, surface area, and pore size and distribution may be altered by optional subsequent processing steps to selectively remove carbon and/or silica.
