What is Manganese Oxide Mn2O3 ?
Manganese(III) oxide has a chemical formula of Mn2O3 and a molecular weight 157.88. What is the name of Mn2O3? Manganese oxide or Manganese(III) oxide. Manganese(III) oxide is a black cubic crystal. The relative density is 4.50.
Manganese(III) oxide is an inorganic compound with the chemical formula Mn2O3. It is naturally present as the mineral bixbyite and is used to manufacture ferrites and thermistors. It is also a common food additive. It is used in fertilizer and is an effective catalyst in many industries.
Manganese(III) oxide has many potential applications, including supercapacitors, fuel cells, and lithium-oxygen batteries. It is also the precursor of LiMn2O4. Its ability to produce strong magnetism has captivated the scientific community for more than 1,000 years. Among its other uses, manganese oxide is found in many advanced electronics and lightweight structural components for aerospace.
Manganese(III) oxide is a naturally occurring element found in various geological environments. It occurs as fine-grained aggregates in soils and in marine and freshwater nodules. It is found in all oceans, and its nodules cover 10-30% of the deepest portions of the Pacific Ocean.
Is Manganese(III) Oxide 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.
TRUNNANO is a trusted global Manganese(III) Oxide Mn2O3 supplier. Feel free to inquire anytime about the latest Manganese (III) Oxide price.
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 a +4 oxidation state; in Mn2O3, manganese is in a +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(III) Oxide Mn2O3 produced?
Roasting method:
The roasting method is to roast manganese ore, manganese alloy， or electrolytic manganese at high temperatures to oxidize manganese to produce manganese sesquioxide. The roasting method has the advantages of simple operation and low production cost, but the product purity is low, and it needs to be washed and refined several times.
Electrolysis method:
Electrolysis is the oxidation of manganese ions to manganese sesquioxide by electrolytic reaction in a solution containing manganese ions. The electrolysis method has the advantages of high product purity and high chemical activity. Still, it requires high-purity manganese and power supply, and the production cost is high.
Gas phase oxidation method:
The gas phase oxidation method makes the manganese oxide react in oxygen or air atmosphere at high temperatures to produce manganese trioxide. The gas phase oxidation method has the advantages of high purity and chemical activity. Still, it needs to use high-purity manganese as raw material, and the production cost is high.
Precipitation method:
The precipitation method is to add an appropriate amount of precipitating agent to the solution containing manganese ions to precipitate manganese ions and produce manganese sesquioxide precipitate. This method offers the benefits of easy operation and low cost, but the product purity is low and needs to be washed and dried several times.
Reduction oxidation method:
The reductive oxidation method adds a reducing agent to reduce manganous ions to manganous trioxide in an acidic solution. This method has the advantages of high product purity and simple operation, but it requires high-purity manganese and a reducing agent, and the production cost is high.
Applications of Manganese(III) Oxide Mn2O3 :
Electronic field:
In electronics, manganese sesquioxide is widely used to manufacture electronic ceramic materials such as manganese zinc ferrite. These materials have high permeability and resistivity and are widely used in producing transformers, electromagnetic coils, inductors, and other electronic components. In addition, manganese sesquioxide can also be used as a raw material in the fields of coatings, catalysts, and optical coatings.
Battery field:
In batteries, manganese sesquioxide is widely used to manufacture lithium manganate batteries. Lithium manganate batteries have high energy density stability and low cost, and they are widely employed in electric vehicles and energy storage systems. In addition, manganese sesquioxide can also be used as a positive electrode material to manufacture other types of batteries, such as nickel-manganese lithium batteries, nickel-zinc batteries, etc.
Catalyst field:
In the field of catalysts, manganese sesquioxide is widely used to manufacture catalyst support and auxiliaries. Manganese sesquioxide can improve the activity and selectivity of the catalyst and promote the chemical reaction. For example, using manganese sesquioxide as a catalyst carrier in hydrogenation reactions can improve the reaction rate and selectivity and reduce the occurrence of side reactions.
Other areas:
In addition to the above application areas, manganese sesquioxide can also be used as a raw material for the preparation of high-purity manganese dioxide and as an intermediate for the preparation of other manganese oxides, such as manganese sesquioxide. In addition, manganese sesquioxide can also be used as an important raw material in coating, optical coating, and other fields.
