Cement foaming agent, also known as foaming concrete foaming agent, refers to an admixture that can reduce the surface tension of liquid and generate a large amount of uniform and stable foam for the production of foamed concrete. Foaming agent is a kind of substance that can make its aqueous...
What is Mn2O3 Powder?
The properties of Mn2O3 Pulver
Manganese Trioxide is a black cubic crystalline, insoluble and insoluble in water and acetic acids. However, it can be soluble or inorganic acids. When heated to 1080, it becomes Mn3O4 (and O2) It is dissolvable in cold hydrochloric to a brown solution. In Chemicalbook hot dilute or concentrated sulfuric acids, it can be made into a solution that is reddish in color. When heated, it will decompose into Mn3O4 (and O2) and manganese-nitrate in hot acid. It comes in two forms: a–Mn2O3 (g-Mn2O3) and g–Mn2O3 (g-Mn2O3).

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°C 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. Pulverized material can then be heated to 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 250C for three 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 as a precursor to soft magnetic material.
4. Used as a raw ingredient in the production of lithium ion battery electrode materials.
5. It is both the primary and intermediate product for manganese compound.
