Brief Description
Large crystal fused magnesia is a magnesium ore powder made by melting selected magnesium raw materials at high temperature in an electric arc furnace through a specific production process. It is characterized by high purity, large crystal grains and dense structure.
This special production process gives large crystal fused magnesia excellent physical and chemical properties, such as high thermal shock stability and strong corrosion resistance, making it an important raw material for manufacturing high-grade magnesium bricks, magnesium carbon bricks and amorphous refractory materials.
