Magnesium carbonate used as an additive refractory, boiler and pipe insulation materials, as well as food, medicine, cosmetics, rubber, ink, or the like. Relative molecular mass of magnesium is 84. White monoclinic crystalline or amorphous powder. Non-toxic, odorless gas is stable. Soluble in acid and ammonium salt solution. Easily broken down into carbon dioxide and magnesium oxide when calcined. In case of acid decomposition emit carbon dioxide. Pharmaceutical intermediates, antacids, desiccant, color protection agents, carriers, anti-caking agents; as additives in foods, magnesium carbonate compensation Magnesium carbonate Agent; fine chemical used in the production of chemical reagents; as a reinforcing agent in rubber, fillers; can be used for insulation, high-temperature fire insulation materials; wire and cable manufacturing process important chemical raw materials. Advanced manufacturing glass; ceramic enamel from the surface of the light effect; magnesium production, pigments, paints, cosmetics, shipbuilding, boiler manufacturing. Athletes and towels available.For the manufacture of magnesium, magnesium oxide, fireproof paint, ink, glass, toothpaste, rubber fillers, etc., used as a flour improver food, bread leavening agent.
