Product details
Application and synthesis of Magnesium Carbonate:Magnesium Carbonate Powder Suppliers and Manufacturers in China, As an additive, magnesium carbonate is often used in pharmaceutical intermediates, antacids, desiccants, Magnesium Carbonate 546-93-0|CMgO3.
Magnesium carbonate with a molecular weight of 84.31. White granular powder. It decomposes at 350 ° C and loses carbon dioxide at 900 ° C. Slightly dissolves in cold water, slowly dissolves in acid. The trihydrate is a colorless acicular crystal with melting point of 165℃ and relative density of 1.850. The pentahydrate is a white monoclinic crystal with a relative density of 1.73, which is decomposed by heating in air. The hydrate can be obtained by passing carbon dioxide into the magnesium brine solution and adding sodium carbonate at the same time. The latter can be dried below 50℃ to obtain anhydrous substance. Light magnesium carbonate is white loose powder or easily fragmented. Odorless, relative density 2.2, melting point 350℃. Stable in air, heating to 700℃ to produce carbon dioxide, to produce magnesium oxide, almost insoluble in water, but cause a slight alkaline reaction in water. Insoluble in ethanol, soluble in dilute acid and bubbling.
Application of Magnesium Carbonate:Magnesium carbonate as an additive is often used in medical intermediates, acid agents, desiccant, color protectants, carriers, anti-caking agents; Magnesium carbonate is used as a drug to neutralize gastric acid and treat duodenal ulcer, as an additive and magnesium compensator in food; In fine chemical industry for the production of chemical reagents; In rubber as reinforcing agent, filling agent; Can be used as insulation, high temperature resistant fire insulation material, wire and cable manufacturing process of the important chemical raw materials. Manufacturing of high-grade glass products; Enamel ceramics play the role of surface brightness; Production of magnesium salt, pigment, paint, daily cosmetics, shipbuilding, boiler manufacturing, coating industry used as accessories pigment, paint, ink filler, can increase the whiteness and covering power and athletes wiping hands.
