- Past studies have led to the conclusion that graphite melting point is a point of change from solid metallic graphite to liquid nonmetallic. Here, new experimental values have been obtained for the carbon resistance, temperature coefficient of resistance and specific heat (near to CV) under fast electrical heating. The emergence of a specific heat increase just before melting of graphite is evidenced. It is supposed that the reason for this effect is the formation of pairs of Frenkel defects.
