Electric fused magnesia is mainly produced by melting magnesite ore with a content of over 47% in an electric arc furnace. The chemical indicators of fused magnesia can be divided into 6 major items; 1. Magnesium oxide content; 2. Silicon dioxide content; 3. Iron oxide content; 4. Aluminum oxide content; 5. Caustic soda; 6. Body density; The fused magnesia product has high purity, large crystalline particles, dense structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material and an important raw material for producing high-end magnesia bricks, magnesia carbon bricks, and amorphous refractory materials.
