| Description |
Manganese Carbonate is a water-insoluble manganese source which occurs naturally in the form of mineral rhodochrosite. It can easily be converted to other manganese compounds, such as the oxide by heating.
Manganese carbonate can be widely applied in various fields. In the field of agriculture, it is commonly used as an additive to plant fertilizers, which is effective to cure the crops with manganese deficiency. It can also be applied in ceramics as a porcelain glaze, glaze colorant and flux and it serves as a catalyst in viscose process. Besides, it has been proved to be used as a hematinic in the field of medicine. Other applications of manganese carbonate involve in health foods, chemical industry and etc. |

| Preparation |
Manganese(II) carbonate is mined from its naturally occurring mineral rhodochrosite. The compound may be prepared in the laboratory as a palepink precipitate by adding sodium bicarbonate to a solution of manganese(II) salt saturated with carbon dioxide. The product obtained is monohydrate, MnCO3•H2O. However, if the carbon dioxide-saturated solution, together with the above monohydrate precipitate, is heated in the absence of atmosphere oxygen, the monohydrate MnCO3•H2O is converted into the anhydrous MnCO3. |
Applications:
1. The relative density of light magnesium carbonate is small, the texture is light and soft, it can be used for the excellent
filler.
2. Because of it have the nature of non-burning and the texture is light and soft, it can produce fireproof material and heat
preservation material that is heat insulation and high temperature resistance. Asbestos light Magnesium Carbonate is an excellent insulating material.
3. It can produce ship, boiler and other department.
4. And it also can produce senior glass products, Magnesium, pigment, paint, fireproof paint, printing ink, ceramics, cosmetics, toothpaste, some daily chemical and medical supplies.
5. Food-grade light magnesium carbonate can produce flour additives, dryer, color fixative, carrier, anti-caking agent.
Package:
