Manganese oxide is any of a variety of manganese oxides and hydroxides.[1] These include

Other manganese oxides include Mn5O8, Mn7O12 and Mn7O13.

Minerals

[edit]

It may refer more specifically to the following manganese minerals:

  • Birnessite, (Na,Ca)0.5(MnIV,MnIII)2O4 · 1.5 H2O
  • Buserite, MnO2·nH2O
  • Hausmannite, MnIIMnIII2O4
  • Manganite, MnIIIO(OH)
  • Manganosite, MnIIO
  • Psilomelane, Ba(MnII)(MnIV)8O16(OH)4, or (Ba,H2O)2Mn5O10
  • Pyrolusite, MnIVO2

Manganese may also form mixed oxides with other metals :

  • Bixbyite, (FeIII,MnIII)2O3, a manganese(III) iron(III) oxide mineral
  • Jacobsite, MnIIFeIII2O4, a manganese(II) iron(III) oxide mineral
  • Columbite, (FeII,MnII)Nb2O6, a niobate of iron(II) and manganese(II)
  • Tantalite, (FeII,MnII)Ta2O6, a tantalum(V) mineral group close to that of columbite
  • Coltan, a mixture of columbite and tantalite series
  • Galaxite, MnIIAl2O4, a spinel mineral
  • Todorokite, (Na,Ca,K,Ba,Sr)
