Redox equilibria of sulphur in glassmelts
Kloužek, Jaroslav ; Němec, Lubomír ; Arkosiová, Miroslava
The combination of experimental and computational methods used for the study of redox equilibria of sulphur in glassmelts makes possible to reveal mechanism and time sequence of redox phenomena taking place during melting process. Both methods were applied for the optimization of sc. reducing sulphate refining realized by the addition of sulphate and reducing agent to the glass batch. The results of experiments supported by the model calculation showed that proper combination of both components at the same time improves homogenization and refining of glass melt and suppresses unwanted bubble nucleation at maximal melting temperatures.
