Hard Borosilicates glass contain up to 12% boric anhydride. They are free of alkaline-earth, and the alkaline level is below 5%. They are consequently melted at high temperature, and the furnace specific pull is limited.

The main requirements are the following :

• Glass Quality
• Long furnace life
• Operational flexibility

   

  Saint-Gobain SEFPRO response is based on High Zirconia fused-cast ER1195 RT and Scimos Z.

   

   

  

   

   

  With this type of glass, ER 1195 RT and Scimos Z present a corrosion resistance that is four times better than for a 40% zirconia fused-cast AZS. It is therefore recommended in all zones of heavy wear.
