Naturally occurring manganese dioxide contains impurities and a considerable amount of manganese(III) oxide. Production of batteries and ferrite (two of the primary uses of manganese dioxide) requires high purity manganese dioxide. Batteries require "electrolytic manganese dioxide" while ferrites require "chemical manganese dioxide". [8]
Mn 3 O 4 is sometimes used as a starting material in the production of soft ferrites e.g. manganese zinc ferrite, [14] and lithium manganese oxide, used in lithium batteries. [15] Manganese tetroxide can also be used as a weighting agent while drilling reservoir sections in oil and gas wells. [citation needed]
Manganese(IV) oxide (manganese dioxide, MnO 2) is used as a reagent in organic chemistry for the oxidation of benzylic alcohols (where the hydroxyl group is adjacent to an aromatic ring). Manganese dioxide has been used since antiquity to oxidize and neutralize the greenish tinge in glass from trace amounts of iron contamination. [ 45 ]
Iron(III) oxide in a vial. Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3.It occurs in nature as the mineral hematite, which serves as the primary source of iron for the steel industry.
Manganese may also form mixed oxides with other metals : Bixbyite, (Fe III,Mn III) 2 O 3, a manganese(III) iron(III) oxide mineral; Jacobsite, Mn II Fe III 2 O 4, a manganese(II) iron(III) oxide mineral; Columbite, (Fe II,Mn II)Nb 2 O 6, a niobate of iron(II) and manganese(II) Tantalite, (Fe II,Mn II)Ta 2 O 6, a tantalum(V) mineral group close ...
