Mn2O3 is different from many other transition metal oxides

Overview of Manganese Oxide Mn2O3 Powder

Manganese(III) Oxide is an oxide with a chemical formula of Mn2O3 and a molecular weight of 157.88. Black cubic crystal. The relative density is 4.50. Mn2O3 is different from many other transition metal oxides because it does not use a corundum (Al2O3) structure. Two forms of Mn2O3 are generally recognized, namely α-Mn2O3 and γ-Mn2O3. Mn2O3 is insoluble in water, acetic acid and ammonium chloride solution, but soluble in other inorganic acids. Dissolve in cold hydrochloric acid to form a brown solution, and form a red solution in hot dilute sulfuric acid or concentrated sulfuric acid, decompose into MnO₂ and manganese nitrate in hot nitric acid, and decompose into Mn3O4 by heating and release O₂. Manganese(III) Oxide can be used in the printing and dyeing process of fabrics. It is also used in the oxidation process of carbon monoxide and organic matter. It can also be used to synthesize soft magnetic materials, or as an important base material for the synthesis of lithium-ion batteries.

 Heating MnO2 in air below 800°C will generate α-Mn2O3 (higher temperature will generate Mn3O4). γ-Mn2O3 can be obtained by oxidation and then dehydration of manganese (II) hydroxide. The preparation of many nanocrystalline Mn 2 O 3 has been reported, for example, involving the oxidation of MnII salt or the synthesis of MnO 2 reduction.

Manganese (III) oxide is formed through redox reactions in alkaline batteries:

2 MnO2 + Zn→Mn2O3 + ZnO

Manganese (III) oxide should not be confused with MnOOH manganese (III) oxyhydroxide. In contrast to Mn2O3, MnOOH is a compound that decomposes at about 300°C to form MnO2.

Applications of Manganese Oxide Mn2O3 Powder

Manganese oxide is a highly insoluble, thermally stable source of manganese suitable for glass, optical and ceramic applications. Manganese oxide is a blackish/brown solid, high-purity (99.999%) manganese oxide (MnO) powder and the main natural source of manganese.

Manganese oxide minerals have been used for thousands of years - the ancients used to make pigments and clear glass, and today as ores for manganese, catalysts and battery materials. More than 30 kinds of manganese oxide minerals are distributed in various geological environments.

1. Mn2O3 has a wide range of uses and can be used in the printing and dyeing process of fabrics.

2. It can efficiently catalyze and oxidize organic pollutants and nitrogen oxides, and catalyze organic coupling reactions.

3. It can be used as the precursor of soft magnetic materials.

4. As a raw material for the synthesis of electrode materials for lithium-ion batteries.
