The carbonate is insoluble in water but, like most carbonates, hydrolyses upon treatment with acids to give water-soluble salts.
Manganese carbonate decomposes with release ofcarbon dioxide, i.e.calcining, at 200C to give MnO1.88:
This method is sometimes employed in the production ofmanganese dioxide, which is used in dry-cell batteries and forferrites.[3]
Manganese carbonate is widely used as an additive to plant fertilizers to cure manganese deficient crops. It is also used in health foods, in ceramics as aglazecolorantand flux, and inconcrete stains.[5]
It is used in medicine as ahematinic.
