Annotation

We propose a method of measuring the thermal diffusivity of partially transparent materials at high temperatures. The method is based on the application of the method of plane temperature waves for various thicknesses of the objects under study in the limit of an optically thin layer over a wide interval of heating frequencies. The method is tested by measuring the thermal diffusivity of high-quality fused quartz, which has an appreciable photon component of the heat transfer.
