Abstract

The compression behavior of distorted rutile-type hydrous minerals has attracted much interest because of their high stability under high-pressure conditions. We performed an X-ray diffraction experiment of synthetic guyanaite (β-CrOOH) with distorted rutile-type structure up to 6 GPa at 300-700 K. The data of P-V-T was fitted to a second-order Birch-Murnaghan EoS with following parameters: bulk modulus KT0 = 191±20 GPa, volumetric thermal expansion coefficient α = (3.3±1.5)×10-5 K-1.
