Iron Oxide (Fe3O4) Nanopowder/Nanoparticles

Purity: 99.5+%, Size: 100 nm 

Iron Oxide (Fe3O4) Nanoparticles are high-purity black crystalline oxides characterized by a mixed-valence state of iron. This material is completely insoluble in water but exhibits solubility in acidic solutions, making it a versatile agent for controlled chemical reactions. With a high melting point and robust structural integrity, these nanoparticles are engineered to maintain performance under extreme thermal conditions. The high purity level ensures minimal interference from contaminants, which is essential for maintaining precision in electronic and sensitive catalytic environments. These nanoparticles are designed for seamless integration into both solid matrices and fluid dispersions, serving as a critical component for advanced material science and protective surface engineering.
