Magnetic materials: Magnetic iron oxide particles, due to their special superparamagnetism, have broad application prospects in giant magnetoresistance, magnetic liquids and magnetic recording, soft magnetism, permanent magnetism, magnetic refrigeration, extensive magnetoimpedance materials, magneto-optical devices, magnetic detectors, and other fields. Videotapes generally use needle-shaped iron or iron oxide magnetic ultrafine particles, and nano iron oxide is a new magnetic recording material. Soft magnetic ferrite has been widely used in radio communication, broadcasting and television, automatic control, space navigation, radar navigation, measurement instruments, computers, printing, household appliances, and biomedical fields. Biomedical and other fields: Nano iron oxide is vital in pharmaceutical capsules, drug synthesis, and biomedical technology. α- Fe2O3 has applications in magnetic materials, pigments, catalysis, and biomedical fields and broad application prospects in other fields. For example, nanoscale iron oxide has a good adsorption effect on Cr (VI), high adsorption efficiency, short adsorption time, and can be recycled and reused. It has particular application value for treating Cr (VI) in environmental wastewater; Using nanometers α- The gas-sensitive material made of Fe2O3 has the characteristics of fast response speed, strong selectivity, high sensitivity, and good stability; When preparing transparent iron oxide, if the content of arsenic and heavy metals is strictly controlled, it can be used in industries such as food and cosmetics; Due to its transparent colouring, acid and alkali resistance, as well as non-toxic properties, transparent iron oxide can also be used as a coating for the inner wall of can lids, and has a large number of applications in the United States.
