Product introduction

Physicochemical properties of light high purity magnesium carbonate: white monoclinic crystal or amorphous powder of magnesium carbonate. The composition is generally expressed by X MgCO3 · y Mg (OH) 2 · Z H2O. There are several proportions of X, y and Z, which can be 4:1:4, 4:1:5, 4:1:6, 4:1:7, 3:1:3 and 3:1:4. Non toxic, tasteless, stable in the air. Relative density 2.16. Slightly soluble in water, the aqueous solution is weakly alkaline. The solubility in water is 0.02% (15 ℃). It is easily soluble in acid and ammonium salt solution and decomposes into carbon dioxide in case of dilute acid. When heated above 300 ℃, it decomposes to produce water, carbon dioxide and magnesium oxide.

Product use

Magnesium carbonate is used as an excellent filler and reinforcing agent for rubber products. It can be used as fireproof and thermal insulation material with heat insulation and high temperature resistance. Asbestos light magnesium carbonate is an excellent insulating material, which is used in shipbuilding, boiler manufacturing and other departments. It can also be used to manufacture high-grade glass products, magnesium salts, pigments, paints and daily chemicals. Used as an antacid in medicine. It can also be used as desiccant, color protection agent, carrier and anti caking agent.
