Production of highly crosslinked silicon carbonitride materials

摘要

Production of highly crosslinked silicon carbonitride materials comprises: (a) dissolving a disilane mixture substituted with chlorine and alkyl groups, from the distillation residues of alkyl chlorosilane synthesis in aqueous organic solvent; (b) reacting with gaseous, dry ammonia to a poly silazane mixture; and (c) removing from the precipitated ammonium chloride, and heat treating at 600-1400 deg C after removing the aqueous organic solvent.
