Fundamental measurements have been obtained to deduce the temperature dependence of thermal conductivity for fine-grain G-348 isostatic graphite, which has been used in thermal experiments related to gas-cooled nuclear reactors. Measurements of thermal diffusivity, mass, volume, and thermal expansion were converted to thermal conductivity. Resulting correlations for the thermal conductivity and thermal expansion are presented as functions of temperature from laboratory temperature to 1000°C.
