Manganese oxide
Manganese oxide is any of a variety of manganese oxides and hydroxides.[1] These include
- Manganese(II) oxide, MnO (aka Ferrite Grade)
- Manganese(II,III) oxide, Mn3O4
- Manganese(III) oxide, Mn2O3
- Manganese dioxide, (manganese(IV) oxide), MnO2
- Manganese(VI) oxide, MnO3
- Manganese(VII) oxide, Mn2O7
Other manganese oxides include Mn5O8, Mn7O12 and Mn7O13.
Minerals
It may refer more specifically to the following manganese minerals:
Manganese may also form mixed oxides with other metals such as Fe, Nb, Ta, ... :
- Bixbyite, a manganese iron oxide mineral
- Jacobsite, a manganese iron oxide mineral
- Columbite, also called niobite, niobite-tantalite and columbate
- Tantalite, a mineral group close to columbite
- Coltan, a mixture of columbite and tantalite
- Galaxite, a spinel mineral
- Todorokite, a rare complex hydrous manganese oxide mineral
