Abstract
In situ X-ray diffractions on high-pressure phase of platinum carbide were observed using a laser-heated diamond anvil cell (LHDAC) up to a pressure of 120 GPa with X-rays from a synchrotron radiation source at BL10XU, SPring-8 and BL13A, Photon Factory. The platinum carbide phase was stable at pressures greater than 75 GPa. The structure of platinum carbide has a cubic symmetry with NaCl-type structure.
