TO THE QUESTION OF REACTIONARY INTERACTION IN B-C-N SYSTEM WITH A PRESSURE OF 12 GPa

Abstract

The paper presents experimental results of reacting between carbon nitride and amorphous boron under high pressure and temperature. It is shown that below the degradation temperature of carbon nitride get ordered graphite-like C3N4 phase fails. In a mixture with boron significantly impeded the formation of hetero-graphene phase. At a temperature of about 1500°C is formed finely diamond-like phase crystal size ranging from tens to hundreds of nanometers. Hetero-diamond cBCxN phase has a basic structure of cubic boron nitride in which carbon atoms are replaced atoms of boron and nitrogen.
