Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the Iron Oxide Nanoparticles, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world's largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia's natural gas supply also has a significant impact on the global fertilizer industry and Iron Oxide Nanoparticles industry, especially in Europe. The price of the Iron Oxide Nanoparticles will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world's neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.
Introduction to Nano Iron Oxide Powder
Iron oxide or ferric oxide is a kind of inorganic substance, and its chemical formula is Fe3O4. It is a black crystal with magnetic, so it is also known as magnetic iron oxide. Iron oxide is insoluble in water, alkali solution, ethanol, ether, and other organic solvents. Natural ferric oxide is insoluble in acid solutions and readily oxidizes to ferric oxide (Fe2O3) in the air under wet conditions. It is usually used as a pigment and polish, as well as in the manufacture of audiotapes and telecommunications equipment.
Ferric oxide has ferromagnetic properties and is called ferromagnetic particles if the particle radius is on the nanometer scale.
Nano ferric oxide (Fe3O4) powder is magnetic and can realize directional movement in the external magnetic field. It has superparamagnetism when its particle size is in a certain range, and in the external alternating electromagnetic field, it can generate heat. It has stable chemical performance.
Physicochemical Properties of Nano Iron Oxide Powder
Black Fe3O4 is a mixed-valence oxide of iron with a melting point of 1597℃ and a density of 5.18g/cm3. It is insoluble in water but soluble in acid solution. It appears in nature in the form of magnetite and has strong submagnetite and high conductivity at room temperature.
When an iron wire is burned in oxygen, Fe3O4 will be generated.
When iron comes into contact with air it forms oxides on its surface, and the oxide film itself is not uniformly composed. For example, a piece of low carbon steel can be covered by three oxide films: when it contacts with metal contact FeO forms, contacts with air Fe2O3 forms, and the middle is Fe3O4. Rather, it may be a mixture of saturated solid solutions of three oxides that form the oxide film on the surface of the steel.
At the same time, the thickness of oxide film varies according to different environmental conditions during oxidation. At room temperature, the oxide thickness of relatively pure iron in dry air does not exceed 20 angstroms (1 angstroms =0.1 nm). However, the oxide film thickness increases significantly in humid air and rust spots can be seen on the surface. At this time, oxide deposition is stratified, with a dense amorphous anhydrous layer on the side close to the metal and a thick porous hydrated layer on the side close to the air.
Iron reacts with water vapor to form Fe3O4 and hydrogen.
Fe3O4 has an anti-corrosion effect, such as the blue of iron and steel parts (also known as burning blue and baking blue) is to use the oxidation of alkaline oxidizing solution to form a layer of blue-black or dark blue Fe3O4 film on the surface of iron and steel parts, to increase corrosion resistance, luster and beauty.

Preparation Methods of Nano Iron Oxide Powder
Since 2013, a large number of literature on the preparation of nano-Fe3O4 have emerged, and some new preparation processes have also been emerging. The traditional preparation methods of Fe3O4 include the precipitation method, hydrothermal (solvothermal) method, micro emulsification method, and sol-gel method. New preparation methods, such as microwave method, pyrolytic carbonyl pre-body method, ultrasonic method, air oxidation method, pyrolytic reduction method, and polyol reduction method, are gradually becoming the focus of research. In the preparation of Fe3O4, new surfactants and preparation systems have also made breakthroughs. Surfactants have not only been limited to SDS, PEG, CTAB, citric acid, oleic acid, etc., NSOCMCS, and polyacrylamide as modifiers have also been reported. Ethanol - water system, n - propanol - water system, propylene glycol - water system, etc.
