Product introduction of high alumina brick
High alumina brick is a kind of refractory. The main component of the refractory brick is Al2O3, which is formed and calcined from bauxite or other high alumina raw materials. High thermal stability, fire resistance rating above 1770 ℃.
Features of high alumina brick
- High temperature resistance
- Slag resistance
- Thermal stability
- Chemical resistance
