Raw Materials for Fused Magnesite Refractory Products

Fused Magnesium Oxide (also called as Electro Fused Magnesium Oxide; Electro Fused Magnesium Oxide; Fused Magnesia; Electrical Grade Magnesium Oxide etc.) powder is produced by using the high purity Magnesium Oxide as raw material, by electric melting method at over 3000℃.

The Fused Magnesium Oxide has the characteristics like excellent transparency and high hardness of crystallinity, the volume density is 3.5g/cm³. Melting point is 2800℃. It is insoluble in water and ethanol, solube in acid and ammonium salt. High purity magnesium oxide is from seawater not mineral, resulting in low impurities. Fused magnesium oxide has excellent high temperature resistance and electrical insulation.

The use of large crystal fused magnesium: 
Large crystal electric melting magnesium is mainly used in refractory materials, spray filler, electric fusion ramming material, furnace filler, coating material, refractory mud, building materials, etc., is made of pure natural high purity light burned magnesium powder by 3000KVA electric melting and large crystal electric melting sand, is a senior alkaline refractory material. With high purity, good ratio of calcium to silicon, large crystal size, stable physical and chemical properties, mainly used in metallurgy, chemical industry, electrical appliances, aerospace and national defense and other industrial fields.
