How can magnesia be classified?

Magnesia is mainly divided into re-burned magnesia, fused magnesia, mid-range magnesia and high-purity magnesia. The fused magnesia manufacturers will give you a detailed introduction below. Light burnt magnesia powder manufacturer

The burnt magnesia is made from natural magnesite ore and calcined in a high-temperature shaft kiln. The purpose of burnt magnesia: raw materials for making bricks and producing unshaped refractory materials, and the finished products are used for steelmaking, electric furnace bottom and ramming furnace lining.

Fused magnesia is made by fusing selected special A-grade natural magnesite or high-purity light-burned magnesia particles in an electric arc furnace. The product has high purity, large crystal grains, dense structure, strong slag resistance, and good thermal shock stability. Therefore, the use of heavy fused magnesia is: it is an excellent high-temperature electrical insulation material, and it is also a high-grade production An important raw material for magnesia bricks, magnesia carbon bricks and unshaped refractories.

The mid-grade magnesia is produced from light-burned magnesia with 97% MgO content as raw material, and is produced by processes such as ball pressing and high-temperature shaft kiln calcination. The product has good sintering degree and dense crystals. The purpose of mid-range magnesia is: it is a high-quality raw material for the production of mid-range magnesia refractory products.

High-purity magnesia is made by flotation and purification of natural super magnesite ore, which is lightly burned, finely ground, pressed ball, and calcined in ultra-high temperature oil shaft kiln. The purpose of high-purity magnesia is: it is a high-quality raw material for making bricks and indeterminate refractory materials.
