Fused magnesia is a commonly used refractory material with a wide range of applications. Some people may not be very familiar with electric fused magnesia. Next, we will briefly introduce the main components of fused magnesia, its characteristics, and its main uses. We hope it will be helpful to everyone.

Fused magnesia is mainly made by melting magnesite ore with a magnesium content of more than 47% in an electric arc furnace. The chemical indicators of fused magnesia can be divided into six main categories: 

1. Magnesium oxide content; 

2. Silica content; 

3. Ferric oxide content; 

4. Alumina content; 

5. Alkali content;
6. Bulk density.

Fused magnesia products have high purity, large crystal grains, dense structure, strong slag resistance, good thermal shock stability, and are excellent high-temperature electrical insulation materials. They are also important raw materials for producing high-grade magnesia bricks, magnesia carbon bricks, and unshaped refractory materials.

The main characteristics of fused magnesia products are complete structure, compact organization, high melting point (up to 2800°C), stable chemical properties,high compressive strength, strong insulation performance, resistance to erosion and corrosion. They are important raw materials for metallurgy, building materials, light industry, furnace lining, and loose materials. They are also indispensable refractory materials for the steel, cement, glass, and non-ferrous metal smelting industries. The main uses of electric fused magnesia are as follows: it can be used as auxiliary refractory materials such as spray repair materials and ramming materials, as well as special refractory bricks such as ladle bricks, magnesia bricks, and magnesia chrome bricks. It can also be used as refractory lining in vacuum and non-vacuum induction furnaces and electric arc furnaces. It is an ideal raw material for making magnesia crucibles, furnace linings, and various high-temperature sleeves.

After the brief introduction of the composition, characteristics, and uses of electric fused magnesia mentioned above, it is believed that everyone has gained a further understanding of electric fused magnesia. If you would like to learn more about electric fused magnesia, please feel free to contact us at any time.
