Graphitizing and non-graphitizing carbons (alternatively graphitizable and non-graphitizable carbon) are the two categories of carbon produced by pyrolysis of organic materials. Rosalind Franklin first identified them in a 1951 paper in Proceedings of the Royal Society. In this paper, she defined graphitizing carbons as those that can transform into crystalline graphite by being heated to 3000°C, while non-graphitizing carbons don't transform into graphite at any temperature. Prec… WebNov 1, 2024 · The graphitization of amorphous carbon catalyzed by metals was discussed in several publications , , , , , , , . Two kinds of mechanisms were well-known: (i) the dissolution-precipitation mechanism; (ii) metal carbide formation-decomposition mechanism. It is generally thought that Fe catalyzes graphitization by the former mechanism …
