抄録

Phase relation among h-BN/w-BN/c-BN was observed using cubic anvil apparatus with synchrotron radiation. Starting material was pyrolytic hexagonal boron nitride (p-BN). Above 4. 5GPa, wurtzite phase (w-BN) reported to be stable above 10GPa was appeared at room temperature, while h-BN was unchanged. At temperature above 1000°C, diffraction peaks of c-BN was appeared at pressure higher than 7. 5GPa. Clear temperature dependence of the transition boundary from w-BN to c-BN was not observed. The transition boundary to c-BN lay between 7 . 1 and 7. 5 GPa with no temperature dependence up to 2000°C.
