Magnesia zirconia brick adopts high purity fused magnesite and synthetic sintered magnesia as the main material, after high pressure forming, high temperature firing, excellent erosion resistance to alkali metal, oxide and sulfide. The magnesia zirconia bricks are of high density( bulk density)greater than 3.08g/cm3. It is resistant to alkaline erosion atmosphere basic slag corrosion, it is widely used in glass furnace, regenerative chamber, cement kiln, electric steelmaking furnace and nonferrous metallurgy smelting.
Characteristics of Magnesia Zirconia Bricks

- Resistance to slag
- The spalling resistance
- High temperature resistance
Application of Magnesia Zirconia Bricks
Magnesia zirconia bricks are mainly used in regenerative chamber of glass furnace.
