High Purity Corundum Brick
High purity corundum brick is made of imported tabular corundum and
high purity fused corundum as raw material .By adding superfine
powder, after mixing, forming ,drying, firing at the high
temperature in shuttle kiln, the whole process is finished.
The quality of corundum brick has reached or exceeded the level of
similar products at home and abroad.
1. Al2O3 content is ≥99%.
2. Good thermal shock resistance.
3. High temperature strength.
4. Good corrosion and slag resistance.
5. Low creep and thermal expansion coefficient.
6. Good performance of anti-stripping.
Primarily used for the key parts of heating furnace.
