ABSTRACT:
The present invention provides a method for measuring thermal conductivity of a material at a stationary state at an elevated temperature T. The method is essentially composed of the steps of: (a) preparing a specimen of the material having first and second surfaces parallel to each other, thickness defined by the first and the second surfaces being constant, a sectional area parallel to the first and the second surfaces of the specimen being constant through the specimen; (b) measuring heat flows Q1 to QN through the specimen at thermally stationary states S1 to SN wherein the temperature of the first surface of the specimen is To which is far lower than the temperature T and the temperature of the second surface of the specimen is T1 to TN which are in the vicinity of the temperature T, T1 to TN corresponding to the states S1 to SN; and (c) calculating the thermal conductivity of the specimen on the basis of the thickness and sectional area, temperatures of the first and the second surfaces, and heat flows through the specimen.
