As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.
For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.
Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the MnO2 in the chemical industry will also be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the 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.

China's non-manufacturing purchasing managers index for March was released by the China Federation of Logistics and Purchasing and the Service Industry Survey Center of the National Bureau of Statistics today. An index of business activity for the non-manufacturing sector as a whole fell below 50 percent.
China's non-manufacturing business activity index was 48.4%, down 3.2 percentage points from the previous month. The new orders index was 45.7 percent, down 1.9 percentage points from the previous month, indicating a significant slowdown in the growth of supply and demand in the non-manufacturing sector from the previous month. In terms of sectors, the business activity index and new order index of transportation, accommodation and catering, culture, sports and entertainment, and tourism-related industries all declined significantly from the previous month.
