Abstract

In this study, Effect of increasing amount of manganese oxide on ultraviolet-visible spectrum in sodium silicate glasses containing iron oxide has been investigated. Iron oxide is existed as ferric and ferrous ions in glasses that presence of manganese oxide leads to iron attend as ferric ions. In this state, glasses absorption ultraviolet light and can be used as a filter of ultraviolet light. In this study, the effect of increasing amount of manganese oxide by ultraviolet-visible spectroscopy has been investigated and changing of ferrous and ferric ions has been measured by wet chemical analysis..
