[Solar] Reduced Iron Content Glass Melting And Refractory Selection

Solar panels require a glass with high transmission properties. This characteristic is obtained mainly by reducing the iron content of the glass and induces a significant change in the melting process compared to a standard soda lime glass. As a consequence, refractory materials used in melting furnaces have to be selected carefully to provide the best glass quality and a longer campaign life. According to the author of this article, some innovative refractories have been developed by Saint-Gobain SEFPRO to fulfil these specific requirements, with positive effects compared to standard AZS blocks and sub-paving mortar.
