Manganese(II,III) oxide Manganese(II,III) oxide Manganese(II,III) oxide is the chemical compound with formula MnO. Manganese is present in two oxidation states +2 and +3 and the formula is sometimes written as MnO.MnO. MnO is found in nature as the mineral hausmannite. MnO formed when any manganese oxide is heated in air above 1000 °C. Considerable research has centred on producing nanocrystalline MnO and various syntheses that involve oxidation of Mn or reduction of Mn. MnO has been found to act as a catalyst for a range of reactions e.g. the oxidation of methane and carbon monoxide; the decomposition of NO, the reduction of
Manganese, Minnesota Manganese, Minnesota Manganese was a small village in Wolford Township, Crow Wing County, Minnesota, United States. Manganese lies roughly north of Trommald, Minnesota. Just off County Road 30, it is perhaps best identified by its location between Coles Lake and Flynn Lake. First appearing in the 1920 census, the village was abandoned by 1960. Named after the mining of its namesake, the village first appeared as "Manganese Village" in the 1920 Census with a population of 183. A post office called Manganese was in operation from 1912 until 1924. Over time, like most other minerals in the Cuyuna Range, all
