Iron oxide is an inorganic substance with a chemical formula of Fe2O3, which is a red or dark red amorphous powder. The relative density is 5~5.25, and the melting point is 1565°C (decomposes at the same time). Insoluble in water, soluble in hydrochloric acid and sulfuric acid, slightly soluble in nitric acid. It has strong hiding power and tinting power, no oil permeability and water permeability.
It has been widely used in the fields of radio communication, radio and television, automatic control, astronautics, radar navigation, measuring instruments, computers, printing, household appliances and biomedicine
Widely used in high-end automotive coatings, architectural coatings, anti-corrosion coatings, powder coatings, is a better environmentally friendly coating.
α-Fe2O3 powder particles have a huge specific surface area and significant surface effect, making it a very good catalyst.
4.Biomedicine and other fields
Nano-iron oxide plays an important role in the fields of medicinal capsules, drug synthesis, biomedical technology and so on.
