Abstract:
The ratio of thermal conductivities and of thermal conductivities to total emissivities were measured for anisotropic ZT-type graphite in the temperature range 1000-2000 C. The emissivity of a sample changes even if it is stored at room temperature for a long time. To obtain the total emissivity of a material, the ratio of specific heat to total emissivity is determined for tantalum, tungsten, molybdenum, and niobium in the temperature range 1000-2000 C. In all cases, it is found that specific heat/total emissivity is a constant, independent of temperature. This permits an easy and accurate determination of the total emissivity of any material.
