The uses of Magnesium carbonate in various aspects

　　Magnesium Carbonate, also called magnesite, is an inorganic salt of carbonic acid. A white powder, it is the main component of the chalk used by gymnasts and rock climbers. Several hydrated and basic forms of magnesium carbonate also exist as minerals.
　　The primary use of magnesium carbonate is the production of magnesium oxide by calcining. Magnesite and dolomite minerals are used to produce refractory bricks.MgCO3 is also used in flooring, fireproofing, fire extinguishing compositions, cosmetics, dusting powder, and toothpaste. Other applications are as filler material, smoke suppressant in plastics, a reinforcing agent in neoprene rubber, a drying agent, a laxative to loosen the bowels, and color retention in foods. In addition, high purity magnesium carbonate is used as antacid and as an additive in table salt to keep it free flowing.
　　Because of its water-insoluble, hygroscopic properties MgCO3 was first added to salt in 1911 to make the salt flow more freely. The Morton Salt company adopted the slogan "When it rains it pours" in reference to the fact that its MgCO3-containing salt would not stick together in humid weather.Magnesium carbonate, most often referred to as 'chalk', is used as a drying agent for hands in rock climbing, gymnastics, and weight lifting.
　　As a food additive magnesium carbonate is known as E504, for which the only known side effect is that it may work as a laxative in high concentrations.
　　Magnesium carbonate is also used in taxidermy for whitening skulls. It can be mixed with hydrogen peroxide to create a paste, which is then spread on the skull to give it a white finish.
　　Magnesium Carbonate can used to absorb oils and other liquid substances.
　　Manufacturers use magnesium carbonate to insulate boilers and pipes against heat and in drugs, including antacids and laxatives. It is also an additive for food, makeup, glass, ink and rubber.
　　In addition it is used to adjust the ph of a product, to reduce its transparent appearance, to increase its volume or to dilute other solids.
　　The use of magnesium carbonate is extensive, Here simply illustrates some basic application industry .specific applications in various industries we can access more information and get more understanding of them.
