Manganese oxide is any of a variety of manganese oxides and hydroxides.Wells A.F. (1984) Structural inorganic chemistry 5th edition Oxford Science Publications, . 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
