Composition and Classification of Corundum Bricks

Corundum brick is a high-temperature refractory material whose main component is alumina. Corundum is a crystal structure formed from aluminum oxide that is highly hard and wear-resistant.

Corundum bricks can be divided into several main categories based on other ingredients and uses in corundum bricks:

Ordinary corundum bricks: The main component is alumina and does not contain other special additives. This type of corundum brick is usually used in general high-temperature fire-resistant situations.

Zirconium corundum bricks: Add a certain amount of zircon stone to alumina to improve the fire resistance and thermal shock stability of corundum bricks. This kind of corundum brick is suitable for harsh high-temperature process conditions.

Chrome corundum bricks: Adding a certain amount of chromium oxide to alumina can improve the corrosion resistance of corundum bricks and is suitable for some high-temperature environments with corrosive atmospheres.

Silicon carbide corundum brick: Silicon carbide is added to corundum brick to improve its wear resistance and impact resistance. This kind of corundum brick is often used in some industrial situations that require high wear and impact.

Mullite corundum bricks: Adding an appropriate amount of mullite to corundum bricks can improve their slag resistance and thermal shock resistance.

The classification of corundum bricks mainly depends on their specific application environment and requirements. In different industrial sectors, different types of corundum bricks may be chosen to meet specific needs.
