Fused magnesia(FM)is produced by smelting of calcined magnesia in electric arc furnaces at above 3000℃. Fused magnesia is considered to be one of the best thermal and electrical insulators with high density, high purity and large crystals.   Application: ● High performance MgO-C refractory bricks for steel industry ● Fired refractory bricks for cement and glass industry ● Heating elements industry
