Fused magnesia is a high-purity oxide formed by high-quality magnesite ore melted at high temperature in an electric arc furnace. It is an important raw material for metallurgy, building materials, light industry, furnace lining and bulk materials, as well as an indispensable important refractory material for steel, cement, glass, non-ferrous metal smelting and other industries. Its main uses are: in the metallurgical refractory industry to make auxiliary refractory materials such as high-purity fused magnesia, gunning material, ramming material, and special refractory bricks such as flow steel mouth bricks, magnesia bricks, magnesia-chrome bricks, etc. Vacuum and non-vacuum induction furnaces and electric arc furnaces are used as refractory linings, and are ideal raw materials for making magnesia crucibles, furnaces and various high-temperature casings.
