Product Description
Fused Magnesia
Fused magnesia: Fused magnesia is a type of refractory material that is produced by the electric arc melting of caustic calcined magnesia, dead burned magnesia or raw magnesite in furnaces at temperatures in excess of 2750C. It has a high melting point, excellent thermal shock resistance, and good chemical stability, making it a popular choice for use in a variety of industrial applications such as steel making, cement manufacturing, and glass production. Application: High performance MgO-C refractory bricks for steel industry; Fired refractory bricks for cement and glass industry; Heating elements industry.

Burned Magnesia
Burned Magnesia: 85%-92% Dead burned magnesia is mainly made of natural magnesite ore with 46% content,which is calcined by high temperature kiln at about 1400℃-1800℃. 94%-98%Dead burned magnesia is made of natural super-grade magnesite ore. It is made by light burning, fine grinding, pressing balls and calcining in ultra-high temperature oil shaft kiln. Application: Burned magnesia is mainly used as raw material for making magnesia bricks and producing amorphous refractory materials. The finished products are used in steel making, electric furnace bottom and ramming furnace.

Large Crystal Fused Magnesia
Large crystal fused magnesia: Large crystal fused magnesia is produced by melting selected high purity light magnesia powder in arc furnace. The product has high purity, dense crystallization, strong slag resistance and good thermal shock stability. Application: Large crystal fused magnesia is an important raw material for making high-grade magnesia carbon brick and amorphous refractory, and is also an excellent high temperature electrical insulation material.
