Magnesium carbonate

1.Property

Monoclinic white crystalline or amorphous powder. Non-toxic, odorless. Stability in the air. 2.16 relative density, micro-soluble in water, was a weak alkaline solution. Solubility in water for 0.02% (15 C). Soluble in acid and ammonium salt solution, the case of acid that break down carbon dioxide emitted, heated to 300 C, decomposition over time, generate water, carbon dioxide and magnesium oxide.

2.Handling and Storage

Store in dry and ventilated house away from moisture. Don't store in goods yards or expose to the air. Protect the material from rain when loading and unloading. Be sure to keep the package dry and free from contaminant.

3.Applications

1), Serves as the medicine intermediate, the absorbent, the drying agent, the color fixative, the carrier, the anti-knot quick medicinal preparation; 

2),Makes the chemical additive, the magnesium element compensation medicinal preparation in food; Uses in the fine chemical industry producing the chemical reagent;

3),Makes the strengthening agent, the auxiliaries in the rubber; 

4), May make the heat insulation, the thermostable fire protection thermal insulation material; In electric wire electric cable process of manufacture important chemistry raw material. 

5),Makes the high-quality glass products; 

6),The enamel ceramics play the superficial luminous role; 

7),Manufacture magnesium salt, pigment, paint, everyday use cosmetics, shipbuilding, boiler manufacture.

8),And the athlete competes scratches the hand to use.

4.Packing

Plastic woven bag or kraft paper bag inner with plastic bag in 20kg/ 50kg/ 500kg/1000kg net.
