The Applications of Mn2O3 Powder

What is it? Mn2O3 Pulver ? Manganese oxide trioxide, a compound with the chemical formula Mn2O3, and a molecularweight of 157.88, is an oxide. Black cubic crystals. Relative densities 4.50 Water, acetic acid, and ammonium chloride solution are insoluble. It is also insoluble in other inorganic acid. Cold hydrochloric acid is used to dissolve the substance to make a brown solution. Hot dilute sulfuric or concentrated sulfuric acids are used to create a red solution. The solution then undergoes decomposition into MnO2 & manganese Nitrate in hot acid. When heated, the solution becomes Mn3O4 which releases O2. It is available in two forms: a–Mn2O3 (or g–Mn2O3). The a-type is made by heating divalent Manganese in air to 600800, and the g type by heating MnO2 in vacuum at 500. For 78 hours. It can be used for the printing and dyeing processes of cloth, as well as in the oxidation process carbon monoxide, organic compounds and nitrate.
Mn2O3 Powder’s characteristics
Manganese Trioxide is a black cubic crystalline, insoluble and insoluble in water, Acetic Acid, and Ammonium Chloride Solution. It is also soluble with other inorganic acid. When heated to 1080, it becomes Mn3O4 or O2. It can be dissolved in cold water chloric acid to a brown solution or in hot dilute sulfuric and concentrated sulfuric acids to a red solution. When heated, it will decompose into MnO2 & manganese nitrate. It comes in two forms: a–Mn2O3 (g-Mn2O3) and g–Mn2O3.

The preparation for Mn2O3 Pulver
1. A-Mn2O3a can be prepared by further oxidation/reduction of manganese oxides or heating divalent Manganese salts in air at 600-800degC. To heat manganese nuitrate hexahydrate, or pure b–MnO2, to a constant temperature at 650 degrees Celsius in air is the best way. Manganese nitrate-hexahydrate is used as the raw material. It must be heated to 190°C to create a solid substance. Pulverization can then be done at 650°C.
2. Preparation of G-Mn2O3 In 350mL the solution, in which 2.2g Manganese Sulfate Tetrahydrate was dissolved was stirred vigorously. Next, 34mL dropwise of 3% Hydrogen Peroxide Solution was added, followed by 50mLs of 0.2mol*dm-3 Ammonia Water to create g–MnO(OH). To make the suspension that emits oxygen darken or black, heat for 4 minutes. Then filter and separate the solid. For gMn2O3, the gMnO(OH) was meticulously dehydrated at 250°C for three consecutive days. You can also prepare g–MnO2 by heating it at 500°C for 78h, under reduced pressure.
Use of Mn2O3 Pulver
1. Mn2O3 can be used for a variety of purposes and is suitable for use in the dyeing and printing of fabrics.
2. It can catalyze the oxidation organic pollutants and of nitrogen oxides.
3. It can be used to make soft magnetic material precursors.
4. Used as a raw ingredient in the production of lithium ion battery electrode materials.
5. It is the primary and intermediate product of the manganese compound.
