Rincian Produk
Manganese(II) carbonate occurs naturally as the mineral rhodochrosite. For lab production, it can be made as a pale pink precipitate by reacting an aqueous manganese(II) salt solution with sodium bicarbonate in a carbon dioxide-saturated environment. This process yields the monohydrate form, MnCO₃·H₂O.

Manganese carbonate is widely used as an agricultural micronutrient additive, helping to address manganese deficiency in crops through fertilizers. Beyond agriculture, it serves as a nutritional supplement in health products. In industry, it acts as both a colorant and flux in ceramic glazes, and is also used in concrete staining. In pharmaceuticals, it functions as a hematinic, supporting blood cell formation by working synergistically with iron, vitamin B12, and folate.
