The process of direct volatilization or reduction oxidation volatilization was employed to produce the mixture of As 2O 3 and Sb 2O 3, and then Na 2SO 4 was added to produce clarificant for glass. The optimizing technology conditions which were obtained from the test of preparing the mixture of pure As 2O 3 and Sb 2O 3 by the volatilization method are reaction temperature 900 ℃ and reaction time about 30 min. The glass clarificant produced meets industrial application standard.展开更多
