Reactions between platinum and germanium in sub/supercritical water were carried out by exposing a platinum plate to an aqueous solution at 20‐40 MPa and 553‐713 K. The surface of the platinum plate was found to be covered with a film of fine crystals of platinum‐germanium compounds, Pt 3 Ge, Pt 3 Ge 2 , Pt 2 Ge and PtGe, depending upon the pressures and temperatures of the environment.
