Abstract: By means of pulse current heating $(3$–$5\,\mu$s$)$, 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.
