Product Description
Magnesium oxide is an alkaline oxide, has the commonness of alkaline oxide, belongs to the gelling material. White or off-white powder, odorless, tasteless, non-toxic, is a typical alkaline earth metal oxide, chemical formula MgO. The melting point is 2852 ° C, the boiling point is 3600 ° C, and the density is 3.58g/cm3 (25 ° C). Soluble in acid and ammonium salt solution, insoluble in alcohol.
Exposed to the air, it is easy to absorb water and carbon dioxide and gradually become basic magnesium carbonate, light products are faster than heavy quality products, and combined with water to generate magnesium hydroxide under certain conditions, a slightly alkaline reaction, and the pH of saturated aqueous solution is 10.3. Soluble in acid and ammonium salt insoluble in water, its solution is alkaline. Insoluble in ethanol. Strong refraction in the visible and near ultraviolet range.


China's annual output of magnesium oxide is about 12 million tons.
One of the main uses of magnesium oxide is the use of flame retardants, traditional flame retardant materials, widely used halogen-containing polymers or halogen-containing flame retardants combination of flame retardant mixture. Used as a standard for white pigments. Light magnesium oxide is mainly used as raw material for the preparation of ceramics, enamels, refractory crucible and refractory bricks. Also used as polishing agent adhesives, coatings, and paper fillers, neoprene and activators. It is used in medicine as an antacid and laxative for gastric acid excess and duodenal ulcer disease. Used in the chemical industry as a catalyst and raw material for the manufacture of magnesium salts.
