I. Properties of Light Magnesium Oxide
The molecular formula of light magnesium oxide is MgO, the relative molecular weight is 40.30, and light magnesium oxide is odorless, odorless, non-toxic white amorphous powder. It is insoluble in water, insoluble in alcohol, soluble in acid or ammonium salt solution. The solubility in water increases with the increase of CO2 content. The melting point is 2852℃ and the boiling point is 3600 ℃ When the temperature rises above 1500 ℃, it will become dead burnt magnesia or sintered magnesia. Absorbing carbon dioxide and water in the air to form basic magnesium carbonate.
II. Use of Light Magnesium Oxide
Light magnesium oxide is mainly used in the production of rubber products and neoprene adhesives. Magnesium oxide plays the role of acid absorbent and promoter in rubber manufacturing, vulcanizing cross-linking in neoprene adhesives, anti-coke agent and resin chelating. Magnesium oxide plays a role in reducing sintering temperature in ceramics and enamels. It is used as filler in the manufacture of grinding wheel and paint, as antiacid and laxative in medicine for the treatment of gastric acid excess, gastric and duodenal ulcer, and as whitening agent or refined decolorizing agent of sugar in food processing. Agricultural use is used as fertilizer and livestock feed. It is the main element in plant and animal metabolism. When used as feed for dairy cows, it can prevent nervous system dysfunction caused by magnesium deficiency. In addition, it can also be used in FRP, dyeing and chemical reagents, electronics industry, insulating materials industry, petroleum additives, foundry, phenolic plastics and other industries.
III.Application of Light Magnesium Oxide
Antiseptics and fungicides, magnetic materials, valve gaskets, magnesium lactate, rubber tube, catalytic additive industry, silicon steel coating, fluorescent agent, EDTA (ethylenediaminetetraacetic acid, chelated magnesium), butyl inner tube, zirconia ceramics, magnesium peroxide, ABS resin, crayon, alumina ceramics
