Isothermal compression of hexagonal graphite-like boron nitride up to 12 GPa

The compressibility of hexagonal graphite-like boron nitride has been measured at room temperature up to 12 GPa, using a diamond anvil cell and X-ray scattering with synchrotron radiation. From the obtained pressure-volume relation for hBN the isothermal bulk modulus of 36.7±0.5 GPa and its first pressure derivative of 5.6±0.2 have been calculated
