High‐Temperature Heat Conductivity of Some Metal Oxides

摘要

A reanalysis of data on the thermal conductivity of certain metal oxides has shown that the deviation from a T-1 law may be fitted to a law exponential in T-1. Thus the deviations may be ascribed to the flow of excitions. The contribution to the thermal conductivity from radiative transfer is shown to be too small to fit the observed deviations.
