View Product Description

Good Abrasion Resistance Al2O3 65% Zirconium Corundum Mullite Compounding Brick

Introduction:

1. The content of AL2O3 is ≥50%.

2. High refractoriness under load. The RUL is higher than fireclay brick as the high content of Al2O3, however, it is lower than silica brick because of mullite crystal does not form reticular tissue.

3. Excellent slag resistance. Zirconia bricks is a kind of neutral refractory material so it enjoys excellent resistance to acid slag and alkali slag corrosion.

Application:

Zirconia bricks is widely used in hot blast stoves, blast furnace, coke oven, rotary kilns of cement and so on.
