发明名称 Ultraviolet radiation-absorbing, colorless, transparent soda-lime silica glass
摘要 An ultraviolet radiation-absorbing, colorless, transparent soda-lime-silica glass as well as glass bottles formed out of the glass are disclosed which, while maintaining high transmittance to light in the visible region and thereby allowing the contents to be seen clearly, absorbs ultraviolet radiation and thus prevents coloration, discoloration, fading in color or deterioration of the flavor of the contents caused by ultraviolet radiation. The glass is characterized in that its composition includes, in % by weight, SO3 . . . 0.15-0.4%; Cerium oxide . . . 0.2-1% (calculated as CeO2); Fe2O3 . . . 0.01-0.08%; FeO . . . 0-0.008%; Manganese oxide . . . 0.01-0.08% (calculated as MnO); and Cobalt oxide . . . 0-0.0005% (calculated as CoO).
