Description
Iron Oxide (Fe₃O₄) Nanopowder (99.5+%, 100 nm, Black, Spherical)
Iron Oxide (Fe₃O₄) Nanopowder/Nanoparticles with a purity of 99.5+% and an average particle size of 100 nm is a high-performance magnetic nanomaterial. Exhibiting excellent superparamagnetic properties, Fe₃O₄ nanoparticles are widely applied in biomedical, electronic, and industrial fields. Their spherical morphology, black appearance, and stable chemical composition make them suitable for coatings, ferrofluids, drug delivery, and advanced magnetic applications.
With a specific surface area between 4–15 m²/g, these nanoparticles provide enhanced reactivity and stability. Fe₃O₄ (Magnetite) is particularly important in fields such as environmental remediation, advanced imaging, and high-density magnetic storage.
