Product description
Zirconium corundum brick is also named AZS brick. It is based on three chemical components of the Al2O3-ZrO2-SiO2 ternary phase diagram and widely used for glass kiln. The glass kiln brick is arranged according to the order of its contents. Al2O3 takes A, ZrO2 takes Z, and SiO2 takes S. The national standard uses this abbreviation. For example, No.33 cast zirconia corundum brick, abbreviated as AZS-33#, No. 36 cast zirconia corundum brick, abbreviated as AZS-36#, No. 41 cast zirconia corundum brick, abbreviated as AZS-41#.
Advantages of CH Refractories manufactured AZS Brick:
Dense structure, low porosity,
It has the characteristics of high volume density, high mechanical strength and high temperature structural strength, and strong resistance to glass liquid erosion.
Application of AZS brick
It is used as the first floor paving brick of glass industrial tank kiln or as sub-layer paving brick to build the bottom and wall of glass tank kiln and thermal equipment such as heat storage checker bricks.
