MANGANESE (II) OXIDE NEW

Application: Manganese monoxide, also known as manganous oxide, is an important kind of manganese compounds, mainly used as raw materials for the production of iron oxide, desiccant of paint and varnish, catalyst for the manufacture of amyl alcohol, beverage adjuvant, trace element fertilizer, smelting, welding, fabric reduction printing and dyeing, glass ceramic coloring and fading, oil bleaching and battery manufacturing.

Chemical properties: The appearance of manganese monoxide is grass green or gray green cubic crystal powder or octahedral crystal. The relative density is 5.43~5.46. The melting point is 1650℃. Dissociation sublimation at 3400℃. Insoluble in water, soluble in acid and ammonium chloride. In hot concentrated ammonium chloride solution, manganese chloride and ammonia are formed. Heating in the air is easily transformed into other high-priced manganese oxide, such as manganese tetroxide, manganese dioxide, manganese trioxide, etc., which is difficult to reduce, and is not reduced by hydrogen at 1200 ° C, and can be reduced by carbon at 1100~1200 ° C. Hydrogen and manganese dioxide are formed in hot water vapor. Co-heated with sulfur, sulfur dioxide and sulfur oxide are formed. Molten in an inert gas does not decompose.
