Title: Thermal Conductivity of Anisotropic Solids at High Temperatures-The Thermal Conductivity of Molded and Pyrolytic Graphites

Journal Article · · Journal of the American Ceramic Society

A method was 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 was used to determine the radial thermal conductivity, k r, and the axial thermal conductivity, kz, of molded ZT-type and pyrolytic graphite in the temperature range 1260 to 2200 deg K. For ZT-type graphite, kz/kr =-- 0.101 + 2.002 x 10-4 x T (1260 deg K < T < 2200 deg K); for pyrolytic graphite, kz/kr = 0.0376 at 1817 deg K.
