A semitheoretical treatment of heat transfer in polycrystalline dielectric ceramics is presented in order to predict the thermal properties of the refractories. Thermal conductivity-temperature curves were determined for 23 high-temperature materials: beryllia, six beryllia-beryllium cermets, a beryllia- beryllium- molybdenum cermet, silicon carbide, three silicon carbide - graphite mixtures, boron nitride, a boron nitride- graphite mixture, four grades of beryllium, and the beryllides of molybdenum, zirconium, titanium, and niobium. Except for beryllium, measurements were made up to 950 or 1000 deg C. Measurements were made by an absolute method requiring a precise measurement of heat input and a comparative method using a material of known conductivity to measure the heat flow.
