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 K regardless of any resultant @C01433@ is incorrect.
