Abstract

Synchrotron X-ray diffraction was used in conjunction with a diamond anvil cell to investigate the properties of tungsten disulfide (WS₂) to 25.5 GPa at room temperature. No pressure medium was used to generate hydrostatic pressure. No phase transformation was observed in the pressure range studied. By fitting the pressure-volume data to the third-order Birch-Murnaghan equation of state, the bulk modulus was determined to be K_0T=61±1 GPa with its pressure derivative K′_0T=9.0±0.3. It is also found that the c-direction of the hexagonal structure is much more compressible than the a-direction.
