High Quality Fused Magnesium Aluminate Spinel for Refractory
Fused magnesium aluminium spinel is produced by mixing the industrial alumina with the high purity caustic-burned magnisa,smelting with high temperature more than 2000 degree centigrade in the electric arc furnaces .
And it can be processed into various sizes of particles according to the clients' demands. Its grain is well developed with the features of compact texture and uniform structure,and therefor is the high-grade raw material for producing refractory products with high intensity and good thermal shock resistance .
