|
The governing equations and the initial and boundary conditions of interactions between gas (vapour) phase and a glass melt are presented for the following processes: precipitation of the sulphate layer on the glass level and its interaction with the melt, volatilization of a glass component from the melt without chemical reaction and with chemical reaction on the phase boundary or in the gas phase (reactive evaporation). In addition, the special cases of the physical and chemical evaporation are presented. |
