Magnesium carbonate

Details:

Magnesium carbonate is white monoclinic crystalline or amorphous powder. We can arrange the shipment, Physicochemical Properties Magnesium carbonate is white monoclinic crystalline or amorphous powder. Its chemical compositions generally is expressed in x MgCO3· y Mg(OH) 2· z H2O, of which the proportions of x, y and z have several different kinds and can be 414, 415, 416, 417, 313 and 314. And nontoxic, odorless, stable in the air. Relative density is 2.16. Slightly soluble in water, and its aqueous solution shows weak alkaline reaction. Its solubility in water is 0.02% (15°C). Easily soluble in acid and ammonium salt solution, it shall resolve and send out carbon dioxide while meeting with diluted acid. Heated to 300°C and above, it shall resolve and produce water, carbon dioxide and magnesium oxide.  UseMagnesium carbonate used as high-quality filler and reinforcement agent of rubber products; as well as fireproof and thermal insulation materials resistant to high temperature. Light magnesium carbonate with a basis of asbestos is high-quality isolation material used for ship and boiler manufacture. And it also can be used to manufacture high-grade glass articles, magnesium salt, pigment, paint and chemicals for daily use, etc. It can be used as anti-acid agent in pharmaceutical industry. And also can be used as desiccant, color retention agent, carrier and anti-caking agent.
