Properties, Storage and Cautions
Iron nanoparticles are highly reactive and flammable and must be handled with great care. Rapid movements and vibrations should be avoided. The nanopowder must be protected from sunlight, heat, moisture, and impacts. Because particle coagulation is a significant concern, the powder should be vacuum-sealed and stored in cool, dry conditions with minimal air exposure.
Applications
Iron nanoparticles exhibit strong electrical and magnetic properties, enabling their use in magnetic probes, magnetic data storage, vacuum seals, magnetic separators, MRI contrast agents, hard metal degradation, transistor applications, and related high-performance technologies.
