Brown iron oxide
CAS:1317-61-9
Brown nano-sized iron (III) oxide is a mixed valence oxide of iron. Its chemical composition can be expressed as a mixture of Fe₂O₃, FeOOH, and Fe₃O₄. It has a melting point of 1597℃, is insoluble in water, and soluble in acid solutions. It has anti-corrosion effects and forms a layer of Fe3O4 film on the surface of steel parts to enhance corrosion resistance, luster and aesthetics. It has excellent safety and environmental friendliness.
Application of brown iron oxide
1. It is used as an analytical reagent, for pigment preparation and in the electronics industry.
2. It is used as a pigment for watercolor, oil paint and ink. In the coating industry, it is used to produce anti-rust paint and other primers. In the construction industry, it is used to color artificial marble and cement floors. In the electronics and telecommunications industry, it is used to make magnetic steel and also serves as the cathode plate of alkaline dry batteries. In the machinery manufacturing industry, it is used for flaw detection of steel.
3. It is used in pigments and polishes, etc., for coloring coatings, plastics and building surfaces.
4. Metallurgy, electronics, textiles and other industries, as well as pigments for use as catalysts, polishing agents, paints and ceramics, glass colorants, etc.
5. Ceramic, nano-ceramic, composite ceramic substrates, ferrite materials.
6. Anti-ultraviolet materials, microwave absorbing materials.
7. Magnetic sealing: By taking advantage of the magnetic property and deep black color of nano-Fe3O4 powder, it can be used to produce magnetic recording materials, high-gradient magnetic separators, microwave absorbing materials, special coatings, and electrostatic copying toners.
