A method of measuring the thermal conductivity of refractory oxides at high temperatures is described. Heat is generated inductively in a metal susceptor inside a hollow specimen in the shape of a prolate spheroid, the temperature of which is measured at two points by means of an optical pyrometer. The conductivities of alumina, magnesia, and beryllia were measured between 1000° and 1800°C.
