Role of sodium sulfate in glass technology

Glass and Ceramics Aims and scope Submit manuscript

Sodium sulfate is widely used as a fining agent in high-tonnage glass technology. Since the conditions for redox glassmaking and Fe2+↔Fe3+ equilibrium displacement are formed under the influence of sulfate, the glassmaking process and glass quality largely depend on the quality and particulars of sulfate interaction with a reducing agent. The reactions and stages of sulfate action in the batch and molten glass are examined.
