Hengjia High Purity Magnesia-Alumina Spinel Series selects high-purity alumina and high-purity magnesia raw materials, which are formed through high-temperature sintering into high-purity raw materials. According to different chemical compositions, it is divided into three product series: AM-66, AM-78, and AM-90.
Hengjia high-purity spinel has extremely low impurity content, excellent high-temperature performance, and high-purity spinel is suitable for products such as breathable bricks, seat bricks, steel ladles, electric furnace tops, refractory materials for rotary kilns, and refractory materials for smelting alloys, as well as shaped products containing spinel that can help improve the slag erosion resistance of refractory materials, and solve the problem of material cracking caused by the addition of magnesia raw materials.

Hengjia high-purity magnesia-alumina spinel has the following characteristics:
High refractoriness;
Good high-temperature volume stability;
Excellent resistance to alkaline slag erosion and permeability performance;
Thermal shock stability is good.
