Fused cast zirconia corundum bricks
Fused and cast zirconia corundum products for glass kilns are divided into three grades according to their zirconia content: the nominal content of zirconia of AZS-33 products is 33%; The nominal content of zirconia in AZS-36 products is 36%; The nominal content of zirconia in AZS-41 products is 41%.

Fused brick AZS33-Y is a high-grade refractory material. "AZS" is an abbreviation for "Alumina - Zirconia - Silica" (Alumina - Zirconia - Silicon Dioxide). The "33" usually represents a zirconia (ZrO₂) content of about 33%. This type of brick is mainly composed of corundum (α - Al₂O₃), oblique zircon (ZrO₂) and glass phase (SiO₂). The corundum phase provides high hardness and good wear resistance, the zirconia phase improves the thermal shock resistance of the material, and the glass phase helps bond other phases together at high temperatures.
