MnCO3 Manganese Carbonate Dry / Wet Powder , Manganese Nitrate Salt Manganese Iv Oxide

43.5% purity MnCO3 manganese carbonate dry & wet powder for manganese nitrate salt - industry grade  

Basic Properties of this manganese carbonate dry powder for manganese nitrate salt produce :

Manganese carbonate is a brown solid with the chemical formula MnCO3. Its IUPAC name is Manganese(II) carbonate. The substance has EINECS registry number 209-942-9 and CAS registry number 598-62-9. In addition, it is insoluble in water which is stable and incompatible with strong acids, strong oxidizing agents. Meanwhile, Manganese carbonate may be moisture senstive. When using Manganese carbonate, you should be very cautious about it. On the one hand, you must not breathe its dust. On the other hand, you must avoid contact with skin and eyes.

Molecular formula: MnCO3 for manganese nitrate salt produce

CAS NO : 598-62-9

Appearance: White powder for manganese nitrate salt produce

Manganese carbonate  is rosy triangle crystal or amorphous brown powder. Calcined in the pyrolusite powder direct acidification method, which can shorten process, lower cost and reduce pollution to environment; widely used in ferrite, desulfurizatio, porcelain glaze, varnish, manganese salt, fertilizers, pharmacy and machine parts and agriculture.

What's more, Manganese carbonate can be prepared by manganese sulfate dissolved in water or vapour and then is filtered to remove undissolved substance. In addition, it is purified by hydrogen sulfide to remove impurities such as heavy metals. The mixture is heated, filtrated to produce pure manganese sulfate solution. After that, it will react with ammonium bicarbonate solution at 25～30 °C to generate Manganese carbonate, which is a kind of double decomposition reaction. Finally, the sediments is eluted, dehydrated and hot-air dried at 80～90 °C to gain Manganese carbonate.

 We produce manganous carbonate both technical ( industry ) grade and electronic phosphorization grade,

 about  5000 tons every year.
