Effect of Rare Earth Composite Refiner Agent on Decolorization and Fining of the Floating Glasses

Article Preview

Abstract:

Na2O-CaO-SiO2 flat glasses were prepared with traditional melt-quenching methods.The effect of different fining glass agent,such as Na2SO4,Ce2(CO3)3,Rare earth composite fining agent,and content on the fining and decolourizing of glass was studied. In addition,the effect of rare-earth composite glass fining agent on the fining and decolourizing of molten glass was analyzed.Mechanism of fining was discussed.Comparative results indicate that composite agent is better than a single agent on the effect of clarification and decolourization.increasing the transparency of glass,glass’s strength was increased largely.
