Audited Supplier 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.
Preparation: The electrolytic metal manganese sheet is broken until the particle size is 15μm to obtain manganese particles; The obtained manganese particles are placed in the saggar, and then the saggar is pushed into the atmosphere furnace; Carbon dioxide gas is passed into the atmosphere furnace, the air in the atmosphere furnace is driven out, and then the atmosphere furnace is heated up, and the heating rate is 5ºC/min. When the temperature of the atmosphere furnace reaches 700ºC ~ 750ºC, the constant temperature roasting stage is entered, and the constant temperature roasting is 2 hours. After the constant temperature roasting, hydrogen is injected into the furnace for natural cooling of the material, the cooling time is 5 hours. When the temperature of the material in the furnace is reduced to below 80 ° C, the saggar is removed from the furnace, and then the material in the saggar is ground, and high purity manganese monoxide can be obtained after the grinding. After testing, the purity of the manganese monoxide is 99.92%, the purity of manganese monoxide is high, and the chemical composition and physical properties of manganese monoxide can also meet the requirements of the chemical composition and physical properties of lithium manganese oxide battery materials.
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 1650ºC. Dissociation sublimation at 3400ºC. Insoluble in water, soluble in acid and ammonium chloride. In hot concentrated ammonium chloride solution, manganese chloride 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, and sulfur oxide are formed. Molten in an inert gas does not decompose.
