High purity fused magnesia is mainly made by using 47% content of magnesite ore and melting it in electric arc furnace. The chemical index of high purity fused magnesia can be divided into 6 items; 1, magnesium oxide content; 2, silica content; 3, iron sesquioxide content; 4. Aluminum oxide content; 5. Caustic soda; 6, body dense; High purity fused magnesia products have high purity, large crystalline particles, dense structure, strong slag resistance material, good thermal shock stability, is an excellent high temperature electrical insulation material, but also the production of high-grade magnesia brick, magnesia carbon brick and amorphous refractory material important raw materials.

The main features of high purity fused magnesia products: High purity fused magnesia products are characterized by complete structure, dense organization, high melting point (up to 2800℃), stable chemical properties, high compressive strength, strong insulation, erosion resistance, corrosion resistance, is an important raw material for metallurgy, building materials, light industry, furnace lining and loose materials, but also an indispensable important refractory material for steel, cement, glass, nonferrous metal smelting and other industries.

High purity fused magnesia main uses: high purity fused magnesia can be mainly used for auxiliary refractory materials such as spray filler, ramming material and special refractory bricks such as flow steel brick, magnesia brick, magnesia chrome brick, also can be used in vacuum and non-vacuum induction furnace, electric arc furnace as refractory lining, is the ideal raw material for making magnesia crucible, furnace bile and various high temperature bushing.

Large crystalline fused magnesia production process: large crystalline fused magnesia is mainly the selection of 91-92% magnesium oxide, 0mm-3mm size magnesium oxide particles, melting in the arc furnace to produce. The product has high purity, large crystalline particles, dense structure, strong slag resistance, good thermal shock stability, is an excellent high-temperature electrical insulation material, but also the production of high-grade magnesia brick, magnesia carbon brick and amorphous refractories important raw materials. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components and so on.

Product characteristics of large crystalline fused magnesia: high purity, large melting of crystalline particles, high point junction, dense structure; Good thermal shock stability; Good high temperature bending strength; Good slag resistance and corrosion resistance; Strong thermal conductivity and high insulation.

Large crystalline fused magnesia product use: large crystalline fused magnesia used in steel furnace lining refractory material, is the manufacture of refractory bricks, amorphous refractory materials of high quality alkaline refractory raw materials; It can also be used as a filler to make thermocouples and thermal insulation materials (household appliances, etc.); It can also be used for ceramic raw materials and sintering auxiliaries as well as metallurgy, building materials, chemical industry, national defense, medical equipment and so on.
