立方晶B-C-Nの静的高温高圧合成とキャラクタリゼーション Synthesis of Cubic B-C-N under Static High Pressure and Temperature and its Characterization
Static direct transformation of graphitic BC<SUB>2</SUB>N to cubic forms was discussed on the basis of our results of synthetic experiments and characterizations for the products. The graphitic BC<SUB>2</SUB>N was successfully transformed to diamond-like cubic phases at 7. 7 GPa and 2150-2400°C for 15-60 min using a belt-type high-pressure apparatus. Crystallization of cubic B-C-N compound was confirmed in the products obtained at 2300°C by means of XRD and ATEM. The cubic B-C-N, however, was segregated to diamond and cBN with increasing the synthetic temperature to 2400°C, which was also supported by SEM and AES. The formation behavior seems to provide some conceptions to explore new materials by high-pressure synthesis.
