Description
Iron (Fe) Nanopowder / Nanoparticles (99.55%, 22 nm, Partially Passivated)
Iron (Fe) Nanopowder / Nanoparticles are high-purity metallic iron particles with an average size of 22 nm and a purity of 99.55% (metal basis). These nanoparticles are partially passivated by coating with ~0.9 wt% oxygen, ensuring safe handling and transportation without significantly affecting performance. Their ultra-fine size provides a high specific surface area (45–65 m²/g) and excellent reactivity, making them suitable for advanced technological and industrial applications.
With outstanding magnetic and electrical conductivity properties, iron nanoparticles are widely used in magnetic materials, biomedical applications, and catalysis. Their cubic crystal structure and uniform spherical morphology ensure high performance in specialized research and production processes.
