The first results are given of experiments in rapid (similar to 1 mcs)
heating of graphite of perfect structure by an electric current pulse
. Measurements were performed of the specific enthalpy and specific he
at capacity of the solid and liquid phases during melting, and of the
heat of melting. The electrical resistivity of liquid carbon was measu
red during heating of cylindrical graphite samples in sapphire capilla
ry tubes. Preliminary data are given for the heat capacity of liquid c
arbon up to similar to 10000 K.
