What is the difference between fused magnesia and large crystalline fused magnesia

The fused magnesia is produced by melting magnesite in the electric arc furnace with a content of 47 or more. The chemical index of fused magnesia can be divided into 6 items. (1) the content of magnesium oxide; (b) Silicon dioxide content; 3. Iron oxide content; 4. Content of aluminium trioxide; 5. Caustic soda; 6. Confidentiality; Fused magnesia products have high purity and large crystallite size, Compact structure, strong slag resistance, good thermal shock stability, is an excellent high temperature electrical insulation material, and also an important raw material for making high-grade magnesia brick, magnesia-carbon brick and unshaped refractories.

Main Features of Fused Magnesia Products: Fused Magnesia Products Features: Intact Structure, Dense Structure, High Melting Point ( up to 2800℃), Stable Chemical Properties and Great Compressive Strength, It is an important raw material for metallurgy, building materials, light industry, furnace lining and bulk material, and also an indispensable refractory in iron and steel, cement, glass, nonferrous metal smelting and so on.

Main Applications of Fused Magnesia: Fused Magnesia Sand can be mainly used as Shotcrete, Ramming and other Auxiliary Refractories and Special Refractory Bricks such as Flowing Steel Mouth Bricks, Magnesia Bricks, Magnesia-Chrome Bricks, It can also be used as refractory lining in vacuum and non-vacuum induction furnace and electric arc furnace. It is an ideal material for making magnesia crucible, furnace tank and various high temperature casings. 　

Production Process of Large Crystallized Electric Melting Magnesia: Large Crystallized Electric Melting Magnesia is produced by melting 91-92 MgO and 0mm-3mm MgO particles in electric arc furnace. The product has high purity, large crystal grains and dense structure, High slag resistance, good thermal shock stability, is an excellent high-temperature electrical insulation material, and also an important raw material for making high-grade magnesia bricks, magnesia-carbon bricks and unshaped refractories. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components and so on.

High purity, large melting point and high density of crystallized magnesia products. The thermal shock stability is good. Good high temperature bending strength; It has good slag resistance and corrosion resistance. Strong thermal conductivity and high insulation.

Application of Large Crystallized Electric Melting Magnesia Products: Large Crystallized Electric Melting Magnesia is used in the furnace lining of steelmaking furnace, and it is a high quality basic refractory material for making refractory bricks and unshaped refractories. They can also be used as fillers for making thermocouples and thermal insulation materials (household appliances, etc.); Also can be used for ceramic raw materials and sintering auxiliaries as well as metallurgy, building materials, chemical industry, national defence, medical apparatus, etc.
