Description of High Alumina Refractory Bricks With 80% Al2O3 & 1800℃ Refractoriness For Furnaces And Kilns

High alumina bricks are a type of refractory brick that contains a high percentage of aluminum oxide (Al2O3). They are typically made from bauxite, a naturally occurring mineral that is rich in Al2O3. High alumina bricks are characterized by their excellent high-temperature performance, corrosion resistance, and mechanical strength.

Features of High Alumina Refractory Bricks With 80% Al2O3 & 1800℃ Refractoriness

1. High refractoriness;

2. High temperature strength;

3. High thermal stability;

4. Neutral refractory;

5. Good resistance to acid and basic slag corrosion;

6. High refractoriness under load;

7. High temperature creep resistance;

8. Low apparent porosity;

Product Application of Factory Price Good Quality High Alumina Brick
