Manganese Carbonate CAS#598-62-9
Naturally Sourced – Derived from the mineral rhodochrosite, ensuring a reliable and naturally occurring raw material.
Laboratory Synthesis Ready – Can be easily prepared under controlled conditions using common reagents like sodium bicarbonate and CO₂.
Distinctive Appearance – Forms as a pale pink precipitate, which aids in easy visual identification during synthesis.
Stable Hydrated Form – Typically obtained as the monohydrate (MnCO₃·H₂O), offering stability for various applications.
Manganese(II) carbonate is naturally sourced from the mineral rhodochrosite. In laboratory settings, it can be synthesized as a pale pink precipitate by introducing sodium bicarbonate into a manganese(II) salt solution saturated with carbon dioxide. The resulting compound is the monohydrate form, MnCO₃·H₂O.

Manganese carbonate is widely used as an additive in plant fertilizers to correct manganese deficiencies in crops. Additionally, it finds applications in health supplements, serves as a glaze colorant and flux in ceramics, and is used in concrete staining. In the medical field, it functions as a hematinic—a nutrient essential for blood cell production during haematopoiesis, particularly involving iron, vitamin B12, and folate.
