Manganese oxide Mn2O3 is an important industrial raw material

Koalas were declared endangered in eastern Australia on Friday, with more and more koalas dying from disease, habitat loss, and other threats. Earlier, the koala was considered a vulnerable species, and the Commonwealth Department of the Environment changed its protection level to endangered on the east coast of Queensland, New South Wales, and the Australian Capital Territory. Many koalas in Australia are infected with chlamydia. The disease can cause blindness, infection, and infertility. Last year, the Australian Koala Foundation said Australia had lost about 30 percent of its koala population in the past three years. Without immediate action, the species could become extinct by 2050.
Unlike koalas, which are on the brink of extinction, the market demand for Manganese oxide Mn2O3 will grow substantially.

Overview of manganese oxide Mn2O3

Manganese oxide Mn2O3 is an oxide with chemical formula of Mn2O3 and molecular weight of 157.88. It is a black cubic crystal. The relative density is 4.50. Mn2O3 is different from many other transition metal oxides because it does not adopt corundum (Al2O3) structure. II. Generally recognized form of Mn2O3, i.e 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 Brown solution, form red solution in hot dilute sulfuric acid or concentrated sulfuric acid, decompose into MnO2 and manganese nitrate, and decompose into Mn3O4 and release O2 in hot nitric acid. Manganese trioxide can be used in the printing and dyeing process of fabrics, the oxidation process of carbon monoxide and organic compounds, the synthesis of soft magnetic materials, or the synthesis of lithium-ion batteries as an important basic material.


When MnO2 is heated below 800 ℃ in air, it will form α- Mn2O3 (higher temperature will produce Mn3O4). γ- Mn2O3 can be prepared by oxidation of manganese hydroxide (II) and then dehydration. The preparation of many nanocrystalline Mn2O3 has been reported, such as the oxidation of mnii salt or the synthesis of MnO2 reduction.

Manganese oxide (III) is formed by redox reaction in alkaline battery:

2MnO2 + Zn→Mn2O3 + ZnO

Manganese oxide (III) should not be confused with mnooh manganese hydroxide (III). Compared with Mn2O3, mnooh is a compound that decomposes to form MnO2 at about 300 °C.

Application of manganese oxide Mn2O3

Manganese oxide Mn2O3 is a highly insoluble and thermally stable manganese source, which is suitable for glass, optical and ceramic applications. Manganese oxide is a black / brown solid, high-purity (99.999%) manganese oxide (MnO) powder, which is the main natural source of manganese.

Manganese oxide minerals have a history of thousands of years - the ancients used them to make pigments and transparent glass, and now they are used as manganese, catalysts and battery materials. Manganese is 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. Mn2O3 can effectively catalyze the oxidation of organic pollutants and nitrogen oxides, and catalyze the organic coupling reaction.

3. Mn2O3 can be used as a precursor of soft magnetic materials.

Mn2O3 can be used as the raw material of lithium ion battery.

5. Mn2O3 is the raw material and intermediate product of manganese compounds.

The World Food Program (WFP) of the United Nations (UN) and the European Union (EU) said in a statement that the conflict between Russia and Ukraine poses risks to global food supplies, and called on the international community to increase support for vulnerable countries and jointly address food security challenges. 

A few days ago, the Executive director of the World Food Program, the European Commission's commissioner in charge of crisis management, the French Foreign Minister of the ROTATING EU presidency, and other officials held a meeting in Rome, Italy, to discuss how to deal with the negative impact of the Conflict between Russia and Ukraine on global food security. 

One of the officials told a news conference after the meeting that the world was facing a food supply challenge that would "last for many years" as the conflict between Russia and Ukraine pushed up global food prices and disrupted the Manganese oxide Mn2O3 will continue.
