Fused Magnesite (Ordinary Grade)Fused Magnesite (Ordinary Grade) is manufactured through fusing high quality raw magnesite in electric arc furnace with the characteristics of big crystal, dense structure and strong corrosion resistance. As an excellent basic refractory raw material, its MgO content is between 87 – 98%.
Fused Magnesite (Big Crystal)Fused Magnesite (Big Crystal) is manufactured through fusing high quality calcined magnesite at high temperature in electric arc furnace with the characteristics of complete crystal, dense texture, good high temperature performance and strong corrosion resistance.
Fused Magnesite (Big Crystal) whose MgO content is between 97 – 99% is widely used in refractory industry. Meanwhile, it is also an excellent high-temperature endurable insulating material.

Electrically fused magnesia has gradually won a place in the special refractories group, owing to its physical superiority over the ordinary grades of dead-burned magnesite. The history of its development dates from the world-war period, when considerable interest was aroused in the sources of supply of magnesite in this country. The economic advantages depend largely on the European situation and the prevailing price for the fused material, but the practical advantages of using a totally shrunk, well-crystallized material are obvious. The crystalline material obtained from various grades of raw material differs somewhat in its physical characteristics, and there is a decided difference in the physical properties between dead-burned magnesite and electrically fused magnesia.
