The use of magnesia has attracted more and more attention with the development of magnesia industry. Magnesia has become an important product in industrial production. 97 fused magnesia understands the use of magnesia is of great significance for the better development of the magnesia industry.

A general term for products in which magnesium materials such as magnesia-based magnesite are treated at a high temperature to a degree of sintering. Using a high-temperature equipment such as a shaft kiln or a rotary kiln for one-time calcination or two-step calcination, the magnesite fired from natural magnesite is called sintered magnesia; the magnesite is used as a raw material to be cooled by melting in an electric arc furnace. The latter formed is called fused magnesia; the seawater magnesia is made by extracting magnesium oxide from seawater. Magnesia is one of the most important raw materials for refractory materials, and is used to manufacture various kinds of magnesia bricks, magnesia-aluminum bricks, ramming materials, and charging materials. It contains more impurities and is used for paving steelmaking furnace bottoms.

Magnesia can be divided into fused magnesia, mid-range magnesia, high-purity magnesia and calcined magnesia.

The burnt magnesia is made by using natural magnesite ore and calcined by high temperature shaft kiln. Uses of reburned magnesia: bricks and raw materials for the production of unshaped refractories. The finished products are used in steel making, electric furnace bottoms and linings.

The fused magnesia is obtained by melting a selected special grade A natural magnesite or high purity light burnt magnesium granules in an electric arc furnace. The product has high purity, large crystal grains, compact structure and strong slag resistance, and has good thermal shock resistance. Therefore, the use of heavy fused magnesia is: it is an excellent high-temperature electrical insulating material, and is also made of high-grade Magnesia bricks, magnesia carbon bricks and important raw materials for unshaped refractories.

The mid-range magnesia is produced by calcining magnesia with a MgO content of 97% as a raw material, and is subjected to a process such as pressure ball and high temperature shaft kiln calcination. The product has a good degree of sintering and a dense crystal. The use of mid-range magnesia is: it is a high-quality raw material for the production of mid-range magnesia refractory products.

The high-purity magnesia is obtained by purifying and purifying the natural super magnesite ore by light burning, fine grinding, ball pressing and ultra-high temperature oil shaft kiln. The use of high-purity magnesia is: it is a high-quality raw material for brick making and indefinite refractory materials.
