Electrochemical Study On The Redox Behaviour Of Selenium-Containing Soda-Lime-Silica Melts

Decolorization of white container glasses nowadays is usually achieved by the addition of selenium compounds to the batch. Most of the quantity added, however, is evaporated during melting which is strongly influenced by the redox state of the melt. Therefore, the redox behaviour in selenium-doped soda-lime-silica melts was studied by square-wave voltammetry.
