The transformation of non-graphitic carbon into graphite by heat treatment in the presence of certain metals or minerals.
Note:
Catalytic @G02691@ gives a fixed degree of @G02691@ at lower temperature and/or for a shorter heat treatment time than in the absence of the catalytic additives (or a higher degree of @G02691@ at fixed heat treatment conditions). Often it involves @D01806@ of @C00821@ and @P04795@ of @G02684@ at the @C00876@ particles so that non-graphitizing carbons can be graphitized by this procedure.
