Fused Cast AZS are the most widely used materials both in glass contact and superstructure of glass melting furnaces. They can be classified by their zirconia content, which basically defines their corrosion resistance, into 5 families :
- 17% ZrO2 Super Low Exudation: A novel, exclusive AZS material, combining the excellent properties of these materials (alkali vapour & carry-over corrosion resistance) and eliminating the vitreous phase exudation and its consequences on glass quality!
- 32% - 34% ZrO2: The reference category of fused-cast industry. Main applications include glass contact (paving tiles, working-end walls) and superstructures.
- 36% ZrO2: With its improved corrosion resistance and combined with the "reinforced filling" process, the optimum choice for melter sidewalls application.
- 40% ZrO2: with the highest corrosion resistance within the AZS family, this type of material is used for all demanding glass contact applications in the void free configuration : electrode blocks, submerged walls, throats, and in some cases melter sidewalls. Available as well, for sidewall application, in the specific "reinforced filling" version (RR-EVF).
