How is high-purity magnesia made?

Sintered magnesia is easy to hydrate. 97 fused magnesia 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. It is an excellent high-temperature electrical insulation material, and it is also used to make high-grade magnesia bricks, magnesia carbon bricks and unshaped refractory materials. Important raw materials. Light burned magnesia

Light burned magnesia is a flexural, pressure-resistant, high-strength, air-hard, and cementing material, which is widely used in defense, medicine, chemical, paper, shipbuilding and other industries

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. It is a high-quality raw material for making bricks and indeterminate refractories. The mid-grade magnesia is produced from light-burned magnesia with 97% MgO content as raw material, and is produced by pressing ball and high temperature shaft kiln calcination. The product has good sintering degree and dense crystals. It is a high-quality raw material for producing mid-range magnesia refractory products.
