CONTINUOUS PRODUCTION OF FIBROUS SILICON COMPOUND

摘要

PURPOSE:To continuously produce high grade silicon carbide and silicon nitride from chaff carbide. CONSTITUTION:Chaff carbide is heated by continuous transfer in a heating zone at >=1,300 deg.C in the presence of inert gas nonreactive with carbon to produce fibrous silicon carbide. Chaff carbide is heated by continuous transfer in a heating zone at >=1,300 deg.C in the presence of gaseous nitrogen to produce fibrous silicon nitride.
