Abstract
By means of pulse current heating (3–5 μs), specimens of a new highly oriented pyrolytic graphite (the highly annealing pyrolytic graphite, HAPG) within the temperature range 2500–5000 K were investigated. The temperature, electrical resistance (compared to the initial sizes), and Joule energy of heating were measured. The beginning of graphite melting was registered at 4800–5000 K. It was observed that HAPG is characterized by a lower melting heat as compared to other types of graphite.
