Product Overview
Magnesia alumina spinel brick is an advanced refractory material. Generally, Mg-Al spinel refractory refers to the general structure of MgAl2O4 or MgO-Al2O3, that is, the magnesium aluminum spinel is prepared from high-purity materials, has good corrosion resistance, thermal shock stability. The amount of spinel content in the production of magnesia aluminum spinel brick should keep a proper level. As spinel amount increases, the thermal shock resistance is better, but the strength (especially the flexural strength) is caused by the mismatch expansion. The Al2O3 in the product should not be more than 15%~20%, preferably 10%~18%.

Characters
Good corrosion resistance
Strong thermal shock resistant ability
Higher compressive strength
Good wear resistance
Chromium-free and environmental protection
