  Synopsis      

       Higiant High-Purity magnesia alumina spinel is a kind of high purity raw material, which is made of high purity alumina and high purity magnesia by high temperature sintering. According to different chemical composition, it is divided into am-66 and am-78And am-90 three brand product series.

      Higiant High-Purity  magnesia alumina spinel has very low impurity content and excellent high temperature performance. High purity spinel is applicable to the prefabricated products such as permeable brick, block brick, ladle, top cover of electric furnace, refractories for rotary kiln, refractories for smelting alloy, and shaped products containing spinel, which can help improve the slag erosion resistance of refractories and solve the problems caused by adding magnesia raw materials Material cracking.

Characteristic

Higiant High-Purity  magnesia alumina spinel has the following characteristics:
-----High fire resistance;
-----High temperature volume stability is good;
-----Excellent resistance to alkaline slag erosion and penetration;
-----The thermal shock stability is good.
