Magnesium carbonate can be used as refractory materials, heat preservation materials for boilers and pipelines, as well as additives for food, medicine, cosmetics, rubber, ink, etc. The relative molecular mass of magnesium carbonate is 84.
nature
White monoclinic crystal or amorphous powder. Non-toxic, odorless, stable in gas. The relative density is 2.16. Slightly soluble in water, aqueous solution
Magnesium Carbonate
It is weakly alkaline, and its solubility in water is 0.02% (15°C). Easily soluble in acid and ammonium salt solution. It is easily decomposed into magnesium oxide and carbon dioxide during calcination. In case of dilute acid, carbon dioxide is released. Generally slightly soluble in water. When heated, it easily reacts with water (when hard water is softened) to produce magnesium hydroxide (because magnesium hydroxide is more insoluble than magnesium carbonate). Equation: MgCO3+H2O=Mg(OH)2+CO2
use
Pharmaceutical intermediates, antacids, desiccants, color protectants, carriers, anti-caking agents; used as additives in foods and magnesium compensation
Agent; used in fine chemicals to produce chemical reagents; used as reinforcing agent and filler in rubber; used as heat-insulating and high-temperature-resistant fire-proof and heat-preserving materials; important chemical raw materials in the manufacturing process of wires and cables. Manufacturing high-end glass products; enamel ceramics play the role of surface brightening; manufacturing magnesium salts, pigments, paints, daily cosmetics, shipbuilding, and boiler manufacturing. And for athletes to wipe their hands during competitions.
Used in the manufacture of magnesium salts, magnesium oxide, fireproof coatings, inks, glass, toothpaste, rubber fillers, etc., used as flour improvers, bread leavening agents, etc. in food
