04193 IUPAC Gold Book - non-graphitic carbon 10.1351/goldbook.N04193 N04193 current 1 All varieties of solids consisting mainly of the element carbon with two-dimensional long-range order of the carbon atoms in planar hexagonal networks, but without any measurable crystallographic order in the third direction (c-direction) apart from more or less parallel stacking. Some varieties of non-graphitic carbon convert on heat treatment to graphitic carbon but some others do not (non-graphitizable carbon). amorphous carbon https://goldbook.iupac.org//terms/view/A00294 graphitic carbon https://goldbook.iupac.org//terms/view/G02689 non-graphitizable carbon https://goldbook.iupac.org//terms/view/N04194 PAC, 1995, 67, 473.
