high-pressure graphitization

A term which refers to the solid-state @T06446@ of @N04193@ into @G02684@ by heat treatment under elevated pressure (e.g. \(100\) to \(1000\ \text{MPa}\)) so that a definitely higher degree of @G02691@ is achieved at lower temperature and/or for a shorter heat treatment time than in heat treatment of the same non-graphitic material at atmospheric pressure.
