1600 Degree High Alumina Silica Refractory Brick Refractory Fireclay Brick
China manufacturer refractory hot sale fireclay brick high alumina silica refractory bricks
Description:
Magnesia alumina spinel brick is an advanced refractory material. Generally, it is prepared from high-purity materials, has good corrosion resistance, 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, but the strength is caused by the mismatch expansion. The Al2O3 in the product should not be more than 15~20%, preferably 10~18%.
