Transformation kinetics of chrome oxides upon glass melting

Kinetic studies of the transformations of chromium oxides during heating of the charge and in the molten glass have been carried out. Various degrees of conversion of CrO ₃ and Cr ₂ O ₃ have been shown. The conditions for the equilibrium of chromium oxides in the glass melt in the case of their joint presence have been determined. The conditions for the interaction of chromium and iron oxides in molten glass, including in the surface layer, in which an equilibrium of coloring oxides can be achieved in accordance with the conditions of interaction and the composition of the gas atmosphere, have also been investigated. Low rates of interaction processes in molten glass are due to its high viscosity and low values ??of diffusion coefficients. Il. 6, bibliography: 6 titles.
