Manganese oxide

Manganese oxide is any of a variety of manganese oxides and hydroxides.<ref>Wells A.F. (1984) Structural inorganic chemistry 5th edition Oxford Science Publications, Template:ISBN.</ref> These include

• Manganese(II) oxide, MnO
• Manganese(II,III) oxide, Mn₃O₄
• Manganese(III) oxide, Mn₂O₃
• Manganese dioxide, 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:

• Tantalite, Template:Chem2, a tantalum(V) mineral group close to that of columbite
• Coltan, a mixture of columbite and tantalite series
• Galaxite, Template:Chem2, a spinel mineral
• Todorokite, Template:Chem, a rare complex hydrous manganese oxide mineral
