Magnesia Alumina Spinel Refractory Brick

Introduction:

Magnesia alumina spinel brick is an advanced refractory material. Generally, it is prepared from high-purity magnesite and spinel, has good corrosion resistance and thermal shock stability. The amount of spinel content in the production of magnesia alumina spinel brick should keep a proper level. As spinel amount increases, the thermal shock resistance is better. The Al2O3 in the product should not be more than 15~20%, preferably 10~18%.
