Abstract: Experimental data from various authors on the graphite melting point are reviewed and compared with the results obtained by E.I. Asinovskii, A.V. Kirillin, and A.V. Kostanovskii as presented in their paper 'Experimental investigation of the thermal properties of carbon at high temperatures and moderate pressures' (Usp. Fiz. Nauk. 172 931 (2002) [Phys. Usp. 45 869 (2002)]). It is shown that a considerable amount of available information about the heating of graphite by an electrical current or a laser pulse remained unaccounted for in that paper. A comparative analysis of the data indicates the 4800–4900-K range as the most reliable melting point estimate for graphite under pressures ranging from 0.1 to 3.0 kbar.
