Взаємодія фаз в системі b–bn–b2o3 за високих тисків і температур

Abstract

Phase interaction in the B–BN–B₂O₃ system has been studied at pressure of 7,7 GPa and temperatures up to 2900 K. Experimental investigations of boron subnitride B₆N, boron suboxide B₆O and cubic boron nitride cBN formation have been carried out. Phase content of sintered samples was measured by X-ray analysis. Hardness measurements were performed.
