Manganese oxide

Manganese oxide is any of a variety of manganese oxides and hydroxides. 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:

• Birnessite,
• Buserite,
• Hausmannite,
• Manganite, MnO(OH)
• Manganosite, MnO
• Psilomelane, , or
• Pyrolusite,

Manganese may also form mixed oxides with other metals:

• Bixbyite, , a manganese(III) iron(III) oxide mineral
• Jacobsite, , a manganese(II) iron(III) oxide mineral
• Columbite, , a niobate of iron(II) and manganese(II)
• Tantalite, , a tantalum(V) mineral group close to that of columbite
• Coltan, a mixture of columbite and tantalite series
• Galaxite, , a spinel mineral
• Todorokite, , a rare complex hydrous manganese oxide mineral
