MANGANESE (II) OXIDE Usage And Synthesis
Physical Properties Green cubic crystal; refractive index 2.16; density 5.37 g/cm3 at 23°C; Moh’s hardness 5.5; melts at 1945°C; insoluble in water.
Occurrence and Uses Manganese(II) oxide is used in the fertilizer industry as a source of manganese in fertilizers; in feedstuff formulations; and as an intermediate in the production of several manganese compounds.
Production Manganese(II) oxide is obtained commercially from manganese(IV) oxide (manganese dioxide) by the reduction with hydrogen, carbon monoxide or methane at elevated temperatures (>800°C):
MnO2 + CO → MnO + CO2
MnO2 + H2 → MnO + H2O
The oxide also can be made by thermal decomposition of manganese(II) carbonate or manganese(II) oxalate in the absence of air:
MnCO3 → MnO + CO2
Also, careful dehydration of manganese(II) hydroxide, Mn(OH)2, under controlled conditions in the absence of air yields MnO.
Reactions Manganese(II) oxide is the lowest oxide of manganese and it is purely a basic oxide. It reacts with acids to form their manganese(II) salts:
MnO + H2SO4 → MnSO4 + H2O
MnO + 2HCl → MnCl2 + H2O
The compound also is oxidized by air or oxygen to higher oxides of manganese. When heated cautiously in air, the product is manganese sesquioxide or manganese(III) oxide:
4MnO + O2 → 2Mn2O3
Product use:used for producing ferrite, dryer for coat and varnish, or catalyst for alcohol, and feed assistant agent, micro- element fertilizer. It also can be used in medicine, smelt, jointing, dyeing, color glass, bleaching fat, ceramic, and dry battery etc.
Packing: 25Kg/1000kg//25 kraft paper bag lined with double plastic bag or ton bag packing, pay attention to sealing.
