What is Mn2O3 Powder?

How do you define it?



Mn2O3 Pulver



?
Manganese oxide trioxide, a compound with the chemical formula Mn2O3 has a molecularweight of 157.88. Black cubic crystals. The relative density is 4.50 Water, acetic and ammonium chloride solutions insoluble. Other inorganic acid soluble. Cold hydrochloric acids can be used to dissolve it to make a brown solution. Hot dilute sulfuric or concentrated sulfuric acids will produce a red solution. MnO2 is formed from manganese oxide and MnNitrate when hot nitric, and Mn3O4 is released as O2. You can find it in two forms: a–Mn2O3 (or g–Mn2O3). The a-type of it is prepared by decomposing divalent manganese nitrates, carbonate, chloride, and hydride in the air. For 78-hours, heat MnO2 to 500 at 500. Or, you can dehydrate it by using g–MnO (OH). You can use it in printing, dyeing, and oxidation processes of organic compounds and carbon monoxide.


These are some of the properties of Mn2O3 Pulver


Manganese Trioxide is a dark cubic crystal. It’s insoluble and insoluble with water, acetic acids, ammonium chloride solution and ethanol. When heated to 1080, it becomes Mn3O4 (and O2) It is dissolvable in cold hydrochloric to a brown solution. In Chemicalbook hot dilute sulfuric or concentrated sulfuric acids, it becomes a solution in a red color. When heated, O2 is released. You can find it in two forms: a–Mn2O3 (g-Mn2O3) and g–Mn2O4.

How to prepare Mn2O3 Pulver


1. A-Mn2O3a can be prepared by further reduction, oxidation, or heat treatment of divalent manganese salts at 600 to 800 degrees Celsius. To heat manganese nuitrate hexahydrate, or pure b–MnO2, to maintain a constant weight in the air at 650°C is an option. Manganese nitrate-hexahydrate is used as the raw material. It must be heated to 190°C before it can become a solid substance. Once this has been done, it can then be pulverized at 650°C.

2. Preparation for g-Mn2O3 A 350mL solution in which 2.2g Manganese Sulfate Tetrahydrate was dispersed was used. 34mL dropwise of 3% Hydrogen Peroxide Solution was then added. Then 50mL was added of 0.2mol*dm-3 Ammonia Water to create g-MnO (OH). To make the suspension emitting oxygen darken or black, heat for four minutes. Then filter the solution and rinse it under 1.5L of hot water. Dry the mixture in a vacuum extractor. For gMn2O3, the g-MnO (OH) was dried at 250°C for three consecutive days. It is also possible to make gMnO2 by heating the gMnO2 at 500 degrees Celsius for 78h, under less pressure.


The use of Mn2O3 Pulver


1. The wide variety of applications for Mn2O3 are numerous. It can be used in printing or dyeing fabrics.

2. It has the ability to catalyze the reduction and oxidation organic pollutants as well organic coupling reactions.

3. You can use it as a precursor to soft magnetic material.

4. Used as a raw ingredient in the production of lithium-ion battery electrode materials.

5. It’s the main raw material for manganese compounds and an intermediate product.
