CALCINED BORAZINE CONDENSATE AND PRODUCTION THEREOF

摘要

PURPOSE:To make a calcined borazine condensate perfectly white by calcining a borazine condensate in a flow of gaseous ammonia. CONSTITUTION:beta-Tris(alkylamino)borazine and alkylamine are condensed at >=150 deg.C in a flow of an inert gas. The resulting condensate is molded and calcined by slow heating in a flow of gaseous ammonia to obtain a calcined borazine condensate. Unlike the conventional calcined boron nitride molded body this calcined borazine condensate is white (pure).
