Magnesium Oxide (Electrofused)

Electro-fused Magnesia is Perfect in crystallization, dense in texture better in high temperature property and stronger in corrosion resistance, prepared in electric arc furnaces by fusing calcined magnesite. Fused magnesia is a high performance basic refractory becoming more widely used for its durability under extreme conditions.the electro-fused magnesite is mainly used for making crucibles and lining of furnaces which produce special alloy steels, moreover, the electro-fused magnesite is also a best electrically insulated material.
