Description of Zirconia Corundum Bricks
Zirconia corundum bricks are mainly composed of zirconium oxide and corundum. Its unique composition gives it excellent high temperature resistance, and it can remain stable and intact even in extremely high temperature environments. In addition, it also has excellent wear resistance, enabling it to withstand harsh mechanical friction and extend its service life. These characteristics make zirconium corundum bricks an ideal choice for various high-temperature industrial processes.

Application of Zirconia Corundum Bricks
Zirconia corundum bricks, renowned for their remarkable high – temperature resistance and wear resistance, find extensive applications. In the glass industry, they line the walls and bottoms of glass melting furnaces, enduring the harsh molten glass environment. In steelmaking, they are used in blast furnaces and converters to withstand high – temperature molten metal. They are also applied in non – ferrous metal smelting furnaces and ceramic kilns, playing a crucial role in ensuring the smooth operation of these industrial processes.
Advantages of Zirconia Corundum Bricks
1. High fire resistance: can withstand high temperature above 1700℃, remain stable in high temperature environment, not easy to soften and deform. 2. Strong wear resistance: hard texture, excellent wear resistance, can resist erosion and wear of materials. 3. Good corrosion resistance: has strong corrosion resistance to a variety of chemical substances, can resist acid and alkali erosion. 4. High mechanical strength: has high compressive and flexural strength, can withstand greater mechanical pressure.
