| 1. Magnesia alumina spinel brick Description |
Magnesia alumina spinel bricks are used to improve the thermal stability of magnesia bricks, and alumina is added to the ingredients and produced. Magnesia alumina spinel bricks are made of high-quality magnesia and industrial alumina powder with low calcium content as the main raw materials, which are formed by high-pressure molding and high-temperature firing. It is resistant to quenching and rapid heating, and has good corrosion resistance to solvents such as iron oxide and alkali slag.

| 2. Magnesia alumina spinel brick Feature |
1. Good thermal stability,
2. Its anti-stripping performance is good
3. Long lasting use
4. It can be directly combined with magnesia chrome bricks.
| 3.Magnesia alumina spinel brick Application |
Magnesium-aluminum spinel bricks are widely used in cement rotary kilns, and can also be used in the production of ladle castables. Because they can improve the corrosion resistance of steel linings, they can be widely used in steel refractories.
