Manganese Oxide Mn2O3 CAS 1317-34-6

About Manganese Oxide Mn2O3 :
Manganese(III) oxide is an oxide with a chemical formula of Mn2O3 and a molecular weight of 157.88. What is the name of Mn2O3? Manganese oxide or Manganese(III) oxide. Manganese(III) oxide is Black cubic crystal. The relative density is 4.50.Is Mn2O3 soluble in water? Insoluble in water, acetic acid and ammonium chloride solution, soluble in other inorganic acids. Is Mn2O3 acidic or basic? The oxide in the lower oxidation state of a metal is basic and in the higher oxidation state of the metal it is acidic. For this reason Mn2O3 is basic and Mn2O7 is acidic. It dissolves in cold hydrochloric acid to form a brown solution, turns into a red solution in hot dilute sulfuric acid or concentrated sulfuric acid, decomposes into MnO₂ and manganese nitrate in hot nitric acid, and decomposes into Mn3O4 by heating and releases O₂. RBOSCHCO is a trusted global Manganese Oxide Mn2O3 supplier.

Manganese(III) oxide exists in two forms: α-Mn2O3 and γ-Mn2O3. What is the charge of Mn in Mn2O3? +3. What is the oxidation number of manganese in MnO4-, Mn2O3, and MnO2? In MnO2, manganese is in +4 oxidation state and in Mn2O3, manganese is in +3 oxidation state. The α-type is obtained by decomposing divalent manganese nitrates, carbonates or chlorides, and hydrides in the air to 600-800℃; the γ-type is obtained by heating MnO2 in a vacuum at 500℃ for 78 hours, or It is produced by γ-MnO(OH) dehydration.

How is Manganese Oxide Mn2O3 produced?
1. Preparation of α-Mn2O3
The oxide of α-Mn2O3 manganese oxide is further oxidized or reduced or prepared by heating the divalent manganese salt in the air at 600-800°C. When using manganese nitrate hexahydrate as raw material, it is necessary to heat the heated solid at 190°C, crush and heat it at 650°C in advance.
2. Preparation of γ-Mn2O3
Under vigorous stirring, add 34 mL of 3% hydrogen peroxide solution to 350 mL of a solution containing 2.2 g of manganese sulfate tetrahydrate, and then add 50 mL of 0.2 mol·dm-3 ammonia to generate γ-MnO (OH). The dark brown or black suspension that releases oxygen will boil quickly. After boiling for 4 minutes, filter and separate, wash the solid with 1.5L hot water, add it to a phosphorus pentoxide vacuum dryer, and dry it below 100°C to obtain γ-MnO(OH). The γ-MnO (OH) was carefully dehydrated at 250° C. under reduced pressure for 3 days to produce γ-Mn2O3. As much as possible, γ-MnO2 was heated at 500°C for 78 hours under reduced pressure to prepare γ-Mn2O3.

Applications of Manganese Oxide Mn2O3 :
1. Manganese trioxide can be used in the printing and dyeing process of fabrics;
2. During the oxidation process of carbon monoxide and organic matter. Manganese (III) oxide can also be used to synthesize soft magnetic materials.
3. Manganese trioxide is an important basic material for the synthesis of lithium-ion batteries;
4. Manganese (III) oxide can be used in the printing and dyeing process of fabrics;
5. Manganese oxide (III) can efficiently catalyze and oxidize organic oxides and nitrogen oxides, and catalyze organic conversion reactions;
6, Manganese oxide (III) oxide soft magnetic material precursor;
7. Manganese oxide is used as a raw material for the synthesis of electrode materials for lithium-ion batteries.
