Manganous Carbonate(Electrial Grade)

 

1.Molecular Formula: MnC0₃

2.Molecular Weight: 114.95

3.Nature: CAS No: 598- 62- 9

Rosy thombus crystal or formless light brown powder , relative density 3.125.almost insoluble in water, but slightly soluble in water containing C0₂. Soluble in dilute inorganic acid, slightly soluble in common organic salt, insoluble in liquid ammonia. Stable in dry air, wet easily oxidized to form manganese oxide gradually becomes black, heated hours of the liberation of the C0₂, when water is azeotropic hydrolysis. The boiling potassium hydroxide, the formation of manganese hydroxide.

4.Usage:

The material of ferrite for electrical equipment, Industrial Manganous Carbonate used as catalyst, pigment, drier, the material ofmanganous salts, or used in medicine, mechanical parts and phosphating process. It also can be used in the fertilizer as track element.

Brief introduction of producing method: pyrolusite powder direct acidification method (two-mine method)

1. Chemical combination method: It can save investment and reduce pollution and cost because this method cut the calcination process.

2. Main materials: pyrolusite and pyrite react with vitriol, and then remove the impurities to get manganese sulfate solution, which react with ammonium bicarbonate to produce Manganese carbonate.

Packing: 25kg in plastic woven bag.

Storage: Normal chemical, stored in cool, dry and airiness place, avoid moisture, heat and decay. In transportation, avoid rain and sunlight. Load gently, no breakage. If fire, fight it with water, sand and fire fight machine.
