A device and technique which may be used to measure the group of thermal properties of substances as well as the heat of fusion in the temperature range 800-2000°K using samples shaped as massive cylinders with external heating in regular regimes of the second and third kinds is described. Formulas are obtained from a solution of the thermal problem and the inclusion of initial conditions which may be used to compute the thermal capacity, thermal conductivity, thermal diffusivity in the regular regime of the second kind by means of a single temperature transducer. Results from a trial of the device with samples of graphite, copper, and silver are presented.
