What are the types of magnesia?

Magnesia has high purity, large crystal grains and dense structure. It is a high-quality high-temperature electrical insulating material. The following editor will tell you what types of magnesia? 98 fused magnesia

1. The content of dead-burned magnesia is 90%, 91% and 92%. The products are made of magnesite and sintered by high temperature shaft kiln. The content of MgO is high, usually between 90 and 93%, which is the raw material for the production of ordinary magnesia bricks and amorphous refractories. Fused magnesia manufacturers

2. The medium-grade magnesia content of 94% and 95% is made of super-grade and first-grade magnesite ore, which are sintered by light burning, fine grinding, ball pressing and high temperature shaft kiln sintering. Magnesia has low impurity content, high bulk density and good slag resistance. It is suitable for the manufacture of mid-grade magnesia bricks or magnesia unshaped refractories, etc.

3. The product with high-purity magnesia content of 97% is made of special-grade magnesite ore, which is sintered by light burning, fine grinding, dry briquetting and ultra-high temperature oil shaft kiln. The MgO content is more than 97%, the impurity content is low, the direct bond between crystals is formed, and the structure is dense. It is an ideal raw material for the production of advanced alkaline bricks.

4. The content of fused magnesia is 98%. The product is made of special-grade magnesite or light-burned magnesia as raw material and melted at high temperature in electric arc furnace. The periclase has large grain size, compact structure, strong slag resistance, and excellent volume stability at high temperature. It is a good raw material for advanced alkaline bricks, carbon-containing products and unshaped refractories.

5. Light-burned magnesia is calcined by magnesite in a reflector kiln, with high Mg0 content and strong chemical activity. It is the raw material for the production of high-quality magnesia and synthetic spinel sand by the two-step calcination method.
