摘要：

The lattice parameters of hexagonal graphite-like boron nitride (hBN) have been measured in the temperature range from 300 to 1800 K up to 7 GPa using energy-dispersive powder diffraction of synchrotron radiation. From the obtained p-V-T relation for hBN, the temperature dependence of isothermal bulk modulus (B-0[GPa] = 32.06(4) + 4.47(9).e(-(T[K] - 298)/298)) and pressure dependence of thermal expansion coefficient (beta x 10(6)[K-1] = 40.9(8) - 1.6(2).p[GPa]) have been derived.
