Manganese (II ) carbonate is a chemical compound selected from the group consisting of manganese compounds, and carbonates.

Occurrence

Of course, manganese (II ) carbonate as the mineral is rhodochrosite.

Production and representation

Manganese (II ) carbonate can ( obtained, for example, reaction of manganese sulfate with ammonium carbonate ) by reaction of dissolved manganese ( II) salts with alkaline carbonates.

Properties

Manganese (II ) carbonate is a colorless to light brown (as pink to red mineral ) odorless solid. Above a temperature of 200 ° C it decomposes, with manganese oxides and carbon dioxide are released.

Use

Manganese (II ) carbonate is used as a fertilizer additive, an additive to improve the dielectric properties of barium titanate and for producing ferrites and other manganese compounds. The monohydrate is also used to color ( lilac to violet) of ceramics.
