1.High Refractoriness: Withstands over 1700℃, stable at high – temperature.
2.Strong Abrasion Resistance: Hard texture, resists material erosion.
3.Good Corrosion Resistance: Resists various chemicals.
4.High Mechanical Strength: Bears large mechanical pressure.
Zirconia corundum bricks are applied in glass melting furnaces, steelmaking furnaces, non – ferrous metal smelting furnaces and ceramic kilns due to their excellent properties.
