Abstract
A method has been developed for the determination of the thermal conductivities of anisotropic solids under conditions of two–dimensional, steady–state heat conduction in a cylinder of finite length heated in vacuum by high–frequency induction and radiating heat to the surroundings. The method has been used to determine the radial thermal conductivity, Kr, and the axial thermal conductivity, Kz, of molded ZT‐type and pyrolytic graphite in the temperature range 1260° to 2200°K. For ZT‐type graphite, Kz/Kr=–0.101 + 2.002 × 10−4±T (1260°K < T < 2200°K); for pyrolytic graphite, Kz/Kr= 0.0376 at 1817°K.Keywords
