One method starts with natural manganese dioxide and converts it using dinitrogen tetroxide and water to a manganese(II) nitrate solution. Evaporation of the water leaves the crystalline nitrate salt. At temperatures of 400 °C, the salt decomposes, releasing N 2 O 4 and leaving a residue of purified manganese dioxide. [8]
Manganese oxide is any of a variety of manganese oxides and hydroxides. [1] These include Manganese(II) oxide, MnO; Manganese(II,III) oxide, Mn 3 O 4; Manganese(III) oxide, Mn 2 O 3; Manganese dioxide, MnO 2; Manganese(VI) oxide, MnO 3; Manganese(VII) oxide, Mn 2 O 7; Other manganese oxides include Mn 5 O 8, Mn 7 O 12 and Mn 7 O 13.
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 ]
Manganese(II) oxide is an inorganic compound with chemical formula MnO. [2] It forms green crystals. The compound is produced on a large scale as a component of fertilizers and food additives .
Pyrolusite is a mineral consisting essentially of manganese dioxide (Mn O 2) and is important as an ore of manganese. [7] It is a black, amorphous appearing mineral, often with a granular, fibrous, or columnar structure, sometimes forming reniform crusts. It has a metallic luster, a black or bluish-black streak, and readily soils the fingers.
A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [1] is a chemical compound with the manganate(VII) ion, MnO − 4, the conjugate base of permanganic acid.Because the manganese atom has a +7 oxidation state, the permanganate(VII) ion is a strong oxidising agent.
Manganese(III) oxide is a chemical compound with the formula Mn 2 O 3. It occurs in nature as the mineral bixbyite (recently changed to bixbyite-(Mn) [ 3 ] [ 4 ] ) and is used in the production of ferrites and thermistors .
Other constituents include iron (6 wt. %), silicon (5 wt. %) and aluminium (3 wt. %), with lesser amounts of calcium, sodium, magnesium, potassium, titanium and barium, along with hydrogen and oxygen as well as water of crystallization and free water. In a given manganese nodule, there is one part of iron oxide for every two parts of manganese ...
