Neutral Borosilicates glass is used for pharmaceutical applications. This kind of glass is characterized by a high content of boric anhydride and alumina, a low level of alkaline-earth oxides and an alkaline level significantly lower than the one of soda-lime glass.

Neutral borosilicate glass is often melted in recuperative flame furnaces or electric furnaces.

The main requirements for the operation are : glass quality, long furnace life, operational flexibility

Saint-Gobain SEFPRO response is based on ER 1195 RT and Scimos Z,  high zirconia fused-cast refractories.

With this kind of glass, ER 1195 RT and Scimos Z , present a four times better corrosion resistance than a regular 40% Zirconia Fused-Cast AZS. It is therefore recommended in all heavy wear zones.
