What are the main contents of magnesia? The medium grade magnesia mainly contains 94% and 95%. The medium grade magnesia is produced from light burned magnesia with 97% MgO as raw material through ball pressing, high-temperature shaft kiln calcination and other processes. The product has good sintering degree and dense crystallization. It is a high-quality raw material for producing medium grade magnesia refractory products.

High purity magnesite is produced by flotation purification of natural super grade magnesite through light burning, fine grinding, ball pressing and ultra-high temperature oil shaft kiln calcination. High purity magnesia with magnesium content of 96-97% can be used as ideal raw materials for high-grade magnesia refractories such as magnesia bricks, magnesia bricks, magnesia carbon bricks, tundish ramming materials, magnesia castables, etc.

The fused magnesite is mainly made from magnesite ore with a content of more than 47% by melting in an electric arc furnace. The chemical indexes of fused magnesia can be divided into 6 items; 1. Magnesium oxide content; 2. Silicon dioxide content; 3. Fe2O3 content; 4. Aluminum oxide content; 5. Caustic soda; 6. Body density; The fused magnesia product has large crystal grain, compact structure, slag resistant material and good thermal shock stability. It is an excellent high temperature electrical flange material and an important raw material for making high-grade magnesia bricks, magnesia carbon bricks and amorphous refractories.

Magnesite is a general term for the products of magnesite and other magnesite raw materials that have been treated at high temperature to reach the degree of sintering. Magnesite fired from natural magnesite is called sintered magnesite by one-step or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln; The fused magnesite is formed by melting magnesite in electric arc furnace and cooling it;
