摘要	Formation,, structure and phase transition of BCN compound were investigated by mechanical milling of mixture of graphite and hexagonal boron nitride or annealing the as-milled mixture at high temperature and high pressure. Amorphous BCN(a-BCN) was prepared by milling the mixture for 120 h. A broad and strong absorbed peak locating at 1 400 cm(-1) and two weak peaks locating at 740 and 1 630 cm(-1) respectively were observed in the infrared spectrum of the a-BCN, and a broad Raman scattering peak was found at 1 330 cm(-1) in its Raman spectrum. The binding energies of the a-BCN are 191.9 eV for B-1s, 284.9 and 286.8 eV for C-1s, 398.3 and 400.5 eV for N-1s, respectively. A hexagonal BCN (h-BCN) with lattice constants of a=0.2505 nm, c=0.6664 nm was produced by annealing the a-BCN for 45 min at 1 473 K and 4 GPa. Its infrared absorbed peaks appeared at 1 398, 1 103, 1 024, 925 and 802 cm(-1), respectively, and Raman scattering peaks are observed at 1 328, 1 358, 1 582 and 1 614 cm(-1), respectively. The mechanisms of the formation and phase transition of the BCN compound are discussed.
