Estimate of the radiative thermal conductivity of conducting media at high temperatures

  • Published:
Soviet Physics Journal Aims and scope

Abstract

The radiative diffusion method is used to obtain an equation to calculate the radiative thermal conductivity of a conducting medium from the values of its resistivity, temperature, and refractive index. It is shown that for semiconducting materials with high resistivity (∼ 10−3Ω ·m) the radiative heat transfer compared to the other heat-transfer mechanisms is significant even at room temperature.
