The raw materials of zirconium corundum brick are industrial alumina powder and selected zircon sand. Then, we use a series of manufacturing processes to make them into refractory products with a ZrO2 content of 32% to 44%. Our zircon refractory bricks are designed to withstand high temperatures and provide excellent thermal stability. Usually, we mainly use zirconium corundum bricks for parts corroded by solutions such as glass industrial tank kilns. Besides, whether you need specific dimensions, shapes or compositions, Kerui Refractory can customize the zirconia refractory to fit your unique needs.

In the refractories for glass industry, we often use zirconium corundum bricks as the lining of glass furnace walls and glass melting tanks. It has excellent heat and corrosion resistance. Therefore, it can withstand the erosion and impact of high temperature glass liquids.
Zirconia corundum bricks are often used in high-temperature equipment in the metallurgical industry. Such as converters, electric furnaces, iron-making furnaces, etc. Moreover, it can withstand chemical attacks and protect equipment structures from high temperatures and corrosion.
Normally, customers can also widely use zirconia refractory bricks in kiln structures and thermal insulation layers in the ceramic industry. It can withstand high temperatures and thermal stress. Therefore, it protects the kiln structure from thermal expansion and thermal shock.
In the steel industry, like mullite bricks, zirconium corundum bricks can be used in high temperature areas. Such as ladle, furnace bottom and furnace wall. What’s more, the high performance of zircon refractory bricks can protect the stability and integrity of the furnace structure.
