Types of corundum bricks used in glass kilns and their respective physical and chemical properties

Corundum bricks are the most commonly used type of refractory materials for glass kilns. Corundum bricks are refractory brick products with an aluminum content of >90%. 

They can also be called alumina refractory products.

 

As we all know, corundum has a very high hardness and melting point. At the same time, corundum also has good corrosion resistance and can still have good stability under the action of slag, metal and glass liquid. Therefore, it can still achieve good results when used in high-temperature oxidizing atmospheres or reducing atmospheres of glass kilns above 2000°C. In glass melting furnaces, the most widely used ones are usually α-corundum bricks, α-β corundum bricks and B-corundum bricks.

 

Corundum bricks can be divided into sintered corundum bricks and fused cast AZS bricks according to the basic materials used. In order to better meet the needs of the kiln, other chemical mineral components are usually added during the production process of corundum bricks to form composite products, such as zirconium corundum bricks, zirconium corundum bricks, etc.
