Manganese carbonate decomposes with release of carbon dioxide, i.e. calcining, at 200 °C to give MnO 1.88: MnCO 3 + 0.44 O 2 → MnO 1.8 + CO 2. This method is sometimes employed in the production of manganese dioxide, which is used in dry-cell batteries and for ferrites. [3] Manganese carbonate is widely used as an additive within plant ...

The carbonate is calcined in air to give a mixture of manganese(II) and manganese(IV) oxides. To complete the process, a suspension of this material in sulfuric acid is treated with sodium chlorate. Chloric acid, which forms in situ, converts any Mn(III) and Mn(II) oxides to the dioxide, releasing chlorine as a by-product. [8]
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.

Manganese(II) acetate are chemical compounds with the formula Mn(CH 3 CO 2) 2 ·(H 2 O)n where n = 0, 2, 4. These materials are white or pale pink solids. These materials are white or pale pink solids.
Manganese(II) nitrate is the precursor to manganese(II) carbonate (MnCO 3), which is used in fertilizers and as a colourant. The advantage of this method, based on the use of ammonia ( NH 3 ) and carbon dioxide (CO 2 ) as reaction intermediates, being that the side product ammonium nitrate ( NH 4 NO 3 ) is also useful as a fertilizer.
