Brown powder
Verwenden
Manganese carbonate (MnCO3) is used in the production of iron ore and as a chemical reagent.
Verwenden
Manganese(II) carbonate occurs in nature as the mineral rhodochrosite [14476-12-1] (manganese spar). This ore also is used to produce manganese dioxide (by electrolytic process). The pure compound is used as gemstones; and as a pigment (manganese white).
Verwenden
As pigment"manganese white"; drier for varnishes; in feeds.
synthetische
Manganese(II) carbonate is mined from its naturally occurring mineral rhodochrosite. The compound may be prepared in the laboratory as a palepink precipitate by adding sodium bicarbonate to a solution of manganese(II) salt saturated with carbon dioxide. The product obtained is monohydrate, MnCO3•H2O. However, if the carbon dioxide-saturated solution, together with the above monohydrate precipitate, is heated in the absence of atmosphere oxygen, the monohydrate MnCO3•H2O is converted into the anhydrous MnCO3.
Application
Manganese carbonate is extensively utilized as an additive to plant fertilizers to treat manganese deficient crops. It is also employed in health foods, in ceramics as a glaze colorant and flux, and in concrete stains. It is utilized in medicine as a hematinic (a nutrient required for the formation of blood cells in the process of haematopoiesis. The main hematinics are iron, B12, and folate).
Allgemeine Beschreibung
Manganese(II) carbonate is a chemical compound that has a structure similar to calcite, with octahedral co-ordination symmetry. It is a carbonate that is insoluble in water and on treatment with acid it gives water soluble salts. It is a widely used material in plant fertilization as an additive that cures the magnesium deficiency in crops.
Flammability and Explosibility
Non flammable
