Name: High Purity Magnesium Oxide
Molecular Formula: MgO
Molecular Weight: 40.30

Property:
High purity magnesium oxide is white amorphous powder with good light permeability, odorless, tasteless, and non-toxic. High purity magnesium oxide has the characteristics like excellent alkali resistance and electrical insulating in high temperatures, high thermal expansion coefficient and thermal conductivity. The volume density is 3.58g/cm3 at 25℃. Melting point is 2852 ℃, boiling point is 3600 ℃. It is insoluble in water and ethanol, soluble in acid and ammonium salt. High purity magnesium oxide transforms into crystals after burning in high temperature above 1000 ℃, transforms into dead burned magnesium oxide or sintered magnesium oxide. Absorbing carbon dioxide in the air, high purity magnesium oxide transform into basic magnesium carbonate. 

Application:
High purity magnesium oxide is widely used as high-temperature resistant materials. It is perfect raw materials for ceramic crucibles, substrate and so on with good light permeability in translucent field. High purity magnesium oxide can be used as filling for magnetic device and variety of carriers in electronic materials and electric field. When used as ceramic crucibles, the thermal conductivity of high purity magnesium oxide is twice higher than aluminum oxide, and the loss of electrolyte is only 1/10 of aluminum oxide. High purity magnesium oxide also can be used as filling for heat resistant coating.
