Magnesium oxide

Magnesium oxide commonly known as bitter, also known as magnesium oxide, magnesium oxide is alkaline oxide, with alkaline oxide of the nature, are cementitious materials. Magnesium oxide is a white powder (yellowish for magnesium nitride), odorless, tasteless, non-toxic, magnesium oxide is a typical alkaline earth metal oxide, chemical formula MgO. White powder, melting point of 2852 ° C, the boiling point of 3600 ° C, the relative density of 3.58 (25 ° C). Soluble in acid and ammonium salt solution, insoluble in alcohol.Magnesium oxide application areas: high purity magnesium oxide at high temperatures with excellent alkali resistance and electrical insulation. Thermal expansion coefficient and high thermal conductivity have good light transmittance. Widely used as high-temperature heat-resistant materials. In the field of ceramics used as a translucent ceramic crucible, substrate and other raw materials in the electrical materials, electrical field for magnetic device packing, insulating material filler and various carriers. Used as a ceramic substrate than alumina thermal conductivity is more than 2 times, the loss of electrolyte is only 1/10 of alumina. Can also be used as high-purity fused magnesia raw materials, in the chemical can be used as "analytical pure" magnesium oxide.
