THERMAL RADIATION OF COMPLEX CERAMIC SOLIDS.

Abstract

The normal total emissivities and relative radiant intensities of several complex ceramic oxides were determined theoretically. It was found that the total emissivities for many of the complex solids seemed nearly to follow the equation which states that the normal total emissivity of a complex solid is equal to the sum of the products of the normal total emissivity and the ratio of the mass/densities (relative volume ratio or the mole ratio) of each of the compounds initially present. On a molecular basis, it was found that the vibratory modes of many of the complex ceramic compounds are nearly similar to the cumulative vibratory modes of the simple ceramic compounds. (Author)
