Global MnO2 market trend 2022-2029 What is Manganese Dioxide MnO2 Powder? by Newsjeromechampagne2015

A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including MnO2 .

Introduction to Manganese Dioxide MnO2 Powder
Manganese dioxide is also known as manganese peroxide or black manganese oxide. It is the oxide of tetravalent manganese. The chemical formula is MnO2. The fHm (298K) is -520.71kJ/mol, the melting point is 847℃, and the density is 5.026 g/cm3. The natural MnO2 exists in pyrolusite, and it is a black rhombic crystal or black-brown powder. It has a tetrahedral lattice, which is amphoteric manganese oxide. It is insoluble in water and nitric acid, but gives off oxygen and forms manganese sulfate in hot concentrated sulfuric acid and is chlorinated to manganese chloride in hydrochloric acid. It is fused with caustic soda and oxidant, giving off carbon dioxide to form permanganate. Manganese dioxide is a strong oxidant and can cause combustion and explosion by friction or co-heating with organic matter or other oxidable substances such as sulfur, sulfide, and phosphide. The product exhibits reducibility with strong oxidants such as hydrogen peroxide. MnO2 is converted into Mn2O3 when heated above 480℃ in air, and Mn3O4 when heated above 900℃. It is widely used in steelmaking, glass, ceramics, dry cells, etc.
 
In nature, it exists in the form of pyrolusite and hard manganese ore. It can be extracted from pyrolusite, and can also be prepared by heating decomposition of manganese nitrate or electrolytic manganese dioxide salt. γ -Mno2 is active and can be used as a cathode material for batteries to eliminate polarization. Manganese dioxide can be used as a rust remover, oxidizer, dry battery drying agent, and paint drying agent, also used in manganese salt preparation and the glass industry. 
 
Physicochemical Properties of Manganese Dioxide MnO2 Powder
For manganese dioxide, oxygen atoms are at the top of the octahedron corner and manganese atoms in the octahedron. Octahedron is connected to form a single chain or double chain, forming a tunnel structure of the gap, octahedron, or hexagonal dense or square dense accumulation. Oxidizability: Manganese dioxide is a non-salt oxide, non-amphoteric oxide which does not react with either acid or base. In the presence of reducing agents, is oxidizing. Such as manganese dioxide into the hydrogen flow heating to 1400K to get manganese oxide. Manganese dioxide is heated in an ammonia gas stream to obtain brown and black manganese trioxide. Manganese dioxide is reacted with concentrated hydrochloric acid to obtain manganese chloride, chlorine gas, and water.
 
In the presence of strong oxidants, it also exhibits reducibility. If the manganese dioxide, potassium carbonate, and potassium nitrate or potassium chlorate mixed melting, people can get dark green melt, melt it in water cooling people can get six valence manganese compound potassium manganate. It is a strong oxidant in an acid medium. Strong oxidant, does not burn on its own, but it aids combustion, so please do not place it with flammable materials.

Applications of Manganese Dioxide MnO2 Powder
1. Manganese dioxide is a very good decolorizing agent in the glass manufacturing industry, which can oxidize low ferric salt to high ferric salt, so that the blue-green glass into weak yellow.
2. In the electronic industry it is used to produce manganese zinc ferrite magnetic materials.  
3. Used as the raw material of iron and manganese alloy in the steelmaking industry and heating agent in the casting industry. 
4. Used in gas masks to absorb carbon monoxide. 
5. In the chemical industry it can be used as an oxidant, catalyst for organic synthesis, paint, and ink desiccant.
6. Used as an accelerant for match industry, as a raw material for glaze medicine of ceramics and enamel and manganese salt. 
7. Used for fireworks, water purification, iron removal, medicine, fertilizer and textile printing, dyeing, etc.  
8. Electrolytic manganese dioxide is an excellent depolarizing agent of battery. Compared with the dry battery produced by natural discharge manganese dioxide, it has the characteristics of large discharge capacity, strong activity, small volume, and long life, so electrolytic manganese dioxide has become a very important raw material in the battery industry. 
9. Electrolytic manganese dioxide due to its strong catalytic, oxidation/reduction, ion exchange, and adsorption capacity, after treatment and molding, it is a comprehensive excellent water purification filter material. Compared with the common use of activated carbon, zeolite, and other water purification filter material, it has a stronger ability to decolorize and remove metal.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".

The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.  

The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.

The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.

Affected by several factors, the supply of the MnO2 is erratic and thus its prices are expected to go higher in the future.
