What is ferroferric oxide? TR-Fe3O4can not be regarded as "ferrous metal ferrite" (FeO2), nor as a mixture of ferrous oxide (FeO) and ferric oxide (Fe2O3), but it can be approximately regarded as a compound of ferrous oxide and ferric oxide (FeO·Fe2O3). This substance is soluble in acid but insoluble in water, alkali solution and organic solvents such as ethanol and ether. Natural ferroferric oxide is insoluble in acid solution, and it is easily oxidized in the air in the wet state.
Iron oxide can also be made into particles, nuggets, powders, sputtering targets, tablets, and Nanopowders. In most cases, iron oxide is usually available immediately. High purity, submicron and Nanopowder forms can be considered. Provide other technical, research, and safety (MSDS) information.
Main applications of ferroferric oxide Ferroferric oxide has a wide range of applications because of its simple preparation method, controllable morphology, excellent magnetic properties and biocompatibility.
Magnetic fluid is a stable colloidal magnetic material formed by evenly dispersing ultrafine magnetic particles in an organic liquid, widely used in aerospace, machinery, electronics and medicine. Nanomagnetic fluid was prepared by the coprecipitation method, which can be used for gene therapy and drug delivery. In the middle of the 20th century, magnetic fluid began to be used in the aerospace field to solve the sealing problem in the cosmic environment. Ferroferric oxide nanoparticles with about particle size were selected and dispersed in kerosene under the action of surfactant. This stable magnetic colloid can move under the action of the external magnetic field and achieve a good sealing effect. Dye. Ferroferric oxide, as a black powder, has excellent colouring ability and is an excellent pigment. Especially for ultrafine Fe3O4 powder, its ultrafine particles help adhere to the chromosome's surface. At the same time, ferroferric oxide will not pollute the environment. It is a natural and harmless high-quality dye that can replace other expensive organic dyes with serious environmental pollution.
Drug transport. It can be combined with specific antibodies or targeted drugs by modifying specific functional groups on the surface of ferroferric oxide. Under the directional guidance of an external magnetic field, it can directly reach the lesion site, release drugs, and achieve targeted treatment of lesions. The ferric oxide particles are modified and functionalized with ammonia water to become hydrophilic particles; Then, the surface is coated with the anticancer drug adriamycin (and the outer layer is coated with a polymer). Realizes the directional transport and slow release of drugs, and has a sustained effect on treating cancer cells. By adopting this method, we can achieve the boot treatment of the focus, greatly reduce the dosage of drugs, improve efficiency, and at the same time, effectively avoid damage to other healthy cells of the human body. Preparation method of ferroferric oxide powder Ferroferric oxide, as a common magnetic material, has many preparation methods, mainly physical and chemical. Among them, the chemical method is the most commonly used preparation method, while the commonly used physical methods are physical vapour deposition and mechanical ball milling.
Physical vapour deposition method. Physical vapour deposition (PVD) is a thin film technology with special functions in which metals or compounds are evaporated in a vacuum and then deposited on the surface of the substrate. A thin film of Fe3O4 was deposited on the crystal plane of metal by physical vapour deposition, and the formation of oxide at the interface between metal and Fe3O4 was studied. Although Fe3O4 thin films with high purity and crystallinity can be prepared, this method requires high equipment and strict control of experimental conditions. Therefore, the method seldom prepares ferroferric oxide unless there is a special need. Mechanical ball milling method. Mechanical ball milling is the most primitive physical method to prepare nanoparticles. Fine Fe3O4 particles can be obtained through an extrusion and grinding by a ball mill. The ferroferric oxide precursor powder was ball-milled under vacuum, and liquid nitrogen cooling conditions, and the left and right ferroferric oxide nanoparticles were obtained. With an equal solid-liquid mixing ball milling method, under the protection of argon gas, micron-sized ferroferric oxide was mixed with a certain amount of methanol and then ball-milled for different times to obtain nanometer-sized ferroferric oxide particles with controllable size. Mechanical ball milling is often used in large-scale industrial production because of its large output, simple operation and low requirements for equipment. However, the purity of the sample prepared by this method is not high, which takes a long time and consumes a lot of energy. 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.
