Abstract

1317716 Cubic boron nitride INSTITUT FIZIKI TVERDOGO TELA I POLUPROVODNIKOV AKADEMII NAUK BELORUSSKOI SSR 24 March 1971 7871/71 Heading ClA Cubric boron nitride is produced by subjecting hexagonal boron nitride to simultaneously, a pressure of 50 kbar to 90 kbar and a temperature of from 1800‹ to 3000‹ C. in the absence of a catalyst. The hexagonal boron nitride starting material may be dried if desired prior to reaction.
