High-purity magnesia

High-purity magnesia is a sintered magnesium oxide that the content of magnesium oxide equal to or greater than 99% and volume density greater than 3.43.4g/cm3. Molecular formula MgO, relative molecular mass 40.30, and it is odorless, tasteless, nontoxic. Bulk density is about 3.4g/cm3. The color is white, light yellow or colorless. Melting point at 2800 degrees Celsius. High purity magnesia poorly soluble in water, insoluble in alcohol, soluble in acid or ammonium salt solution, slow absorption of carbon dioxide in the air and water, forming alkali magnesium carbonate.
  
Uses : Because of high purity magnesia with good flexural strength at high temperatures, slag resistance and corrosion resistance, and can improve the service life of furnace lining, so it is widely used in steel furnace lining refractories. It is high quality material of manufacturing refractory brick, not stereotypes refractories. It can also be used as filling material, used to make thermocouples and thermal insulation materials. High-purity magnesia can also be used for ceramic raw materials and additives, as well as metallurgy, building materials, chemical, defense, medical device, and so on.
