Precautions when using fused zirconia corundum bricks

Precautions when using fused zirconia corundum bricks

(1) Irregular changes in thermal expansion

Fused zirconia corundum bricks are characterized by stable and dense structure, and strong resistance to molten glass. There is abnormal expansion between 900-1200℃.

(2) Electrical insulation

Fused zirconium corundum bricks have good electrical insulation and decrease with the increase of temperature. In the production of soda-lime glass furnaces, fused zirconium corundum bricks can be used as electrode bricks.

(3) Thermal conductivity

The thermal conductivity of fused zirconia corundum bricks is more than twice that of clay bricks. Therefore, when making pool wall tiles, the cooling air volume required near the liquid level should be twice as large as when using clay bricks as pool walls.
