AZS Bricks
AZS Bricks, Good Resistance To Alkali Vapor And Thermal Shock. Mainly Used In Glass Furnaces
Alumina-Zirconia-Silica (AZS) refractories, belong to sintered ZrO2_Al2O3_SiO2 products family along with Zircon Mullite, Bonded AZS, Zirconia Corundum, and Rebonded Fused Mullite bricks. Sintered ZrO2-Al2O3_SiO2 products such as AZS have good resistance to alkali vapor and thermal shock. Mainly used in glass furnaces, they can withstand aggressive conditions in contact with molten glass. Typical applications are superstructures, skew blocks, wall bricks and upper-checker in regenerators, paving, sub-paving, and forehearth blocks in float glass furnaces. Rebonded Fused Mullite bricks (MFZ-6) are used as pure-oxygen burner blocks in alkali-free glass furnaces, crown blocks and arch blocks in ceramic frit furnaces, and areas of high temperature and high thermal stress in other industrial furnaces.
