1,Classification:Magnesium carbonate
2,Appearance:white monocline crystallizes or the amorphous powder
3,Cas No:13717-00-5
1,Magnesium carbonate
2,the white monocline crystallizes or the amorphous powder.
3,Non-toxic, tasteless ,
4,Relative density is 2.16.
5,In the water, the peroxide solution assumes the weak basicity slightly soluble, in the water solubility is 0.02% (15°C).
6,Easily soluble in acids and ammonium salt solution. When calcine easy to decompose the magnesia and the carbon dioxide.
7,Meets the diluted acid is the decomposition emits the carbon dioxide. In ordinary circumstances slightly soluble Yu Shui. When heating Yi
Yushui responded (when water softening) produces the magnesium hydroxide (, because magnesium hydroxide is more difficult than magnesium
carbonate to dissolve).
Use:
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

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.
