Product Description of magnesia aluminum spinel brick
Magnesia aluminum spinel brick is the main raw material of pure magnesia and synthetic magnesium priscela. The refractory raw material is obtained by artificial synthesis. The raw material is rarely present in nature and crystalline magnesium stone for industrial use is completely synthetic.
Features of magnesia aluminum spinel brick
- High temperature resistance
- Strong peeling ability
- Good slag resistance
- Good abrasion resistance
