摘要：

Phase formation in the B-C-N system has been studied at pressures from 6 to 15 GPa and temperatures from 1000 to 1600°C using mixtures of carbon nitride (C3N4) nanospheres and boron. A new ternary phase with the structure of cubic boron nitride in which some of the nitrogen and boron atoms are replaced by carbon has been obtained at p ≃ 8 GPa and t ≃ 1500°C. According to the Rietveld refinement results, its composition is BC0.47N0.85.
