Graphite Melting and Properties of Liquid Carbon

The results of fast heating (by electrical pulse current) of highly orieInted pyrolytic graphite specimens are preseInted. Experimental data are obtained for graphite melting: the enthalpy of solid and liquid phases under melting, the heat of melting, and the heat capacity of solid and liquid phases near melting. Liquid carbon resistivity is measured under fast heating of cylindrical graphite specimens in thick-walled sapphire capillary tubes. Preliminary data for the isobaric heat capacity Cp for liquid carbon up to 10,000 K and for the isochoric heat capacity Cv up to 8000 K are preseInted.
