摘　　要：阐述了硫酸盐在高温玻璃熔体中可能发生的化学反应以及硫酸盐发生热分解反应达到平衡时的平衡常数热力学表达式,讨论了硫酸盐在玻璃熔体中作为澄清剂的澄清机理,介绍了硫在玻璃基体中可能存在的价态以及影响硫在玻璃体中的含量的因素。The possible chemical reactions of sulfate in glass melt and the thermodynamics equations of equilibrium constants of sulfate decomposition reaction were introduced.The fining mechanism of sulfate as fining agent in glass melt was discussed. The valence states and the residual content of sulfur in glass were also described.
