On the formation of a solid solution having the diamond-like lattice in the wurtzitic boron nitride-cubic diamond system

Abstract

The results have been reported of electron microscopic studies, which confirm the existence of a contact interaction of particles of cubic diamond and wurtzitic boron nitride at pressure 7.7 GPa and temperature 1700–1900°C to form an interlayer (transition zone) of diamond-like BN. It has been established that in the transition zone there is carbon, whose quantitative portion decreases as it passes from the region that contacts with diamond into the matrix component based on dense BN phases.
