The chemical molecular formula of industrial magnesium carbonate is MgCO3, the molecular weight is 84.31, white granular powder, odorless and tasteless. Slightly soluble in cold water, slowly soluble in acid and insoluble in ethanol.
The chemical molecular formula of industrial magnesium carbonate is MgCO3, the molecular weight is 84.31, white granular powder, odorless and tasteless. Slightly soluble in cold water, slowly soluble in acid and insoluble in ethanol. Appearance is white granular powder, decomposes at 350°C melting point, loses carbon dioxide at 700°C. Magnesium oxide is gradually formed. Magnesium carbonate (afraid of damp, easy to deteriorate when exposed to water).
Industrial magnesium carbonate is mainly used to manufacture magnesium salt, magnesium oxide, fireproof coating, ink, glass, toothpaste, rubber filler; it is used as flour improver and bread leavening agent in food. Magnesium carbonate can also be used to neutralize acids and bases, such as neutralizing acids with magnesium carbonate. It is used as an antacid and laxative in medicine to treat hyperacidity, gastric and duodenal ulcers; magnesium carbonate is an alkaline agent, drying agent, color-protecting agent, anti-caking agent, carrier, bulking agent Agent and acidity regulator; used in the production of chemical reagents in fine chemicals; used as reinforcing agent and filler in rubber; hand use. Manufacture of glass products; enamel ceramics for surface brightening; production of magnesium salts, pigments, paints, daily cosmetics, shipbuilding, boiler manufacturing and other related industries.
The raw materials for the production of magnesium carbonate include magnesite, magnesium hydroxide, dolomite, and brine. The production methods of magnesium carbonate vary according to the raw material route: namely dolomite carbonization method, brine carbonization method, brine soda ash method, brine ammonium bicarbonate method (or brine baking soda method), magnesite carbonization method, bitter soil double decomposition method, asbestos tailings carbonization method. At present, the products that can be produced include light magnesium carbonate, basic magnesium carbonate, heavy magnesium carbonate, non-slip magnesium carbonate for sports, and electronic grade magnesium carbonate.
Magnesium carbonate is an important additive in the development of my country's national economy and modern chemical industry. For example, new energy vehicles, electronic ceramics, rubber, food and other industries are inseparable from magnesium carbonate and its new magnesium material group.
Magnesium resource distribution in the world The world's magnesium resource reserves are extremely rich. Magnesium is one of the 10 commonly used non-ferrous metals, and its reserves are abundant. my country's magnesium resources rank first in the world, laying a foundation for the development of my country's magnesium resource industry.
