Product Details
The dense microstructure of AZS-33# zirconium corundum brick makes the brick resistant to glass erosion, is not easy to produce stones or other defects, and the possibility of producing small bubbles is also very low. Therefore, AZS-33# zirconium corundum brick is the most widely used product in glass furnace.
