graphitization

https://doi.org/10.1351/goldbook.G02691
A solid-state transformation of thermodynamically unstable non-graphitic carbon into graphite by means of heat treatment.
Note:
Graphitization is also used for the @T06446@ of @M03872@ @D01671@ into @G02684@ by heat treatment, as well as in metallurgy for the formation of @G02684@ from thermodynamically @U06569@ carbides by thermal @D01547@ at high temperatures. Such uses of the term graphitization are in line with the above definition. The use of the term graphitization to indicate a process of thermal treatment of @C00841@ at \(T > 2500\ \text{K}\) regardless of any resultant @C01433@ is incorrect.
