Description
Summary:The Rayleigh scattering coefficients of a number of glasses in the K 2OMgOPbOSiO 2 system have been determined. The scattering by density fluctuations and by concentration fluctuations was calculated using theories which were developed for ideal multicomponent liquids. In order to investigate how these theories could be applied to multicomponent glasses, the scattering by concentration fluctuations was calculated making different assumptions. It was found that reasonable agreement, both in trends and in order of magnitude, was obtained between the calculated and observed scattering coefficients when the glass was considered to be a frozen-in mixture of silicate units with compositions corresponding to those of crystalline silicates.
