WebJan 1, 2014 · The specific spectral emissivity ɛ x, which is insensitive to the phase transition, has been observed for two noble metals (Cu and Au) [32], [33], [34] in the … WebFigure 14 illustrates the spectral emissivity of a number of glasses and in addition tabulates the total emissivity for each. Total emissivity is computed by integrating the product of the spectral emissivity and the black body energy over the entire spectrum. As can be seen in the spectral data, the spectral emissivity tends to be high except ...
