Iron Oxide (Fe3O4) Nanopowder/Nanoparticles

High Purity: 99.5+%, Size: 30 nm 

Iron Oxide (Fe3O4) Nanoparticles are high-purity crystalline materials engineered for precision at the nanoscale. These particles exhibit a consistent spherical morphology, which provides a uniform surface area-to-volume ratio and predictable magnetic behavior. A defining characteristic of this nanopowder is its superparamagnetic nature, allowing the particles to become strongly magnetized under an external field while retaining no residual magnetism once the field is removed. This unique behavior, combined with their distinct brown color, makes them highly effective for applications requiring magnetic manipulation and recovery. Furthermore, their high purity ensures chemical stability and prevents interference in sensitive catalytic or biological environments.
