Abstract
Room-temperature volume versus pressure data of anatase was obtained from X -ray diffraction measurements in a diamond anvil cell up to 7.8 GPa. A fit of the pressure-volume data to a Birch-Murnaghan equation of state with an assumed pressure derivative K' of 4 and a zero-pressure unit cell volume V- 0 of 136.74(5) Angstrom (3) yielded an isothermal bulk modulus value for an atase of 178 +/- 1 GPa.
