What is Ferroferric oxide powder? Ferroferric oxide powderis a black powder which is soluble in hot hydrochloric acid and insoluble in water and organic solvents. Cubic crystal structure, ferrimagnetism. Specific saturation magnetization (a. )105riTrr13．g-l； Curie temperature (in) 585℃; Magnetostrictive coefficient (a. ) 18×10-6, magnetocrystalline anisotropy constant (Ki) -1.1×104 J/1113.
Main applications of Ferroferric oxide powder Ferroferric oxide is used to make primer and topcoat. Natural magnetite is also the raw material of iron. Its hardness is so high that it can be used as an abrasive. At the same time, ferroferric oxide is a common magnetic material. Special pure ferroferric oxide is used as the raw material of audio tape and telecommunication equipment. Ferroferric oxide has been widely used in automobile braking fields, such as brake pads, brake shoes, etc. It has been recognized in the field of welding materials in China, and its application in the production of welding electrodes and welding wires is still in its infancy, and its market prospect is very broad. Strong magnetic characteristics, showing good performance in sewage treatment. Chemical properties of ferroferric oxide Iron oxide will be produced when the iron wire is burned in oxygen. Comparing the Gibbs free energy generated by the standard molar of iron oxide, it is concluded that Fe3O4 has the highest thermodynamic stability, so the product is Fe3O4. When iron contacts with air, it will form an oxide on its surface. At this time, the chemical composition of the oxide film itself is not uniform. For example, a piece of low-carbon steel can be covered by three kinds of oxide films: FeO in contact with metal, Fe2O3 in contact with air and Fe3O4 in the middle. More specifically, perhaps the mixture of saturated solid solutions of three oxides forms the oxide film on the steel surface.At the same time, the thickness of the oxide film also varies with different environmental conditions during oxidation. At room temperature, the thickness of relatively pure oxide on iron in dry air is less than 20 angstroms (1 angstrom =0.1 nanometers), but the thickness of oxide film increases obviously in humid air, and rust spots can be seen on the surface. At this time, the deposition of oxide is layered, 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. Price of Ferroferric oxide powder Ferroferric oxide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Ferroferric oxide powder. A large amount of large amount will be lower. The price of Ferroferric oxide powder can be found on our company's official website.
