Ferric oxide (Fe3O4)

Ferric oxide (Fe3O4) is an inorganic compound, also known as magnetic iron oxide or black iron oxide. It is a black crystalline substance with magnetic properties, insoluble in water, alkaline solutions, and organic solvents such as ethanol and ether, but soluble in acidic solutions. In a humid state, ferric oxide easily oxidizes to iron oxide (Fe2O3) in the air. Ferric oxide occurs naturally in the form of magnetite, with a high melting point (1594°C) and density (5.18 g/cm³). It has important applications in fields such as electronics, magnetism, and materials science, and can be used to prepare magnetic materials, electronic devices, and energy storage materials.

    Product Features:

    1. Ferric oxide materials have significant magneto-optical effects, which give them important application potential in magneto-optical storage and other areas. In optical coatings, by reasonably designing the microstructure and distribution of ferric oxide, the optical performance of the film can be further enhanced, such as increasing transmittance and reducing reflection loss.

    2. When metal (such as gold or silver) nanoparticles combine with ferric oxide, surface plasmon resonance effects can occur. This effect can significantly enhance the local electric field, thereby enhancing the optical properties of ferric oxide. Therefore, introducing gold and silver nanoparticles into ferric oxide composites in optical coatings can further optimize the optical performance of the film. 3. Ferric oxide composite coatings can serve as a new type of protective coating, providing corrosion and oxidation resistance. This characteristic gives it potential application value in optical coatings, especially in scenarios where both optical performance and protective performance need to be considered.

    4. The magnetic properties of ferric oxide also increase its applications in environmental pollution control. For example, it can be used to adsorb and clean heavy metal pollutants and organic pollutants. This characteristic suggests that ferric oxide may have the potential to purify the surface environment of the film layer and improve the stability of the film layer in optical coatings.
