We are a leading company specializing in the business of offering our clients Manganese Carbonate. It is a water insoluble manganese source that can easily be converted to other manganese compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. This chemical powder is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. It is a pale pink, water-insoluble solid with formula MnCO3. Manganese Carbonate is mainly used as an additive to plant fertilizers to cure manganese deficient crops.
