What is High Alumina Refractory Brick?
High alumina refractory brick is a kind of refractory brick with high content of alumina. This brick belongs to neutral refractory material. Customers can use high alumina bricks in various industries except the environment of strong acid and strong alkali. Additionally, high alumina refractory brick is known for excellent resistance to high heat and corrosion. To make it clear, we introduce chemical composition of high alumina refractory brick here:
- Alumina: alumina is the primary ingredient of high alumina bricks. Additionally, the Al2O3 content of high alumina brick is commonly 45-95%. The higher the alumina content, the higher the refractoriness.
- Silica: silica is often present in high alumina bricks as a secondary component. It helps to enhance the refractory properties and thermal stability. Besides, the silica content in high alumina bricks is typically below 15%.
- Other additives: high alumina refractory bricks may contain small amounts of mineralizers and fluxes to improve their properties. Besides, the specific composition and amounts of these additives depend on the desired properties of the bricks.
