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.
