Description

Nickel Iron Oxide (NiFe₂O₄) Nanopowder / Nanoparticles (99%, 25 nm)

Nickel Iron Oxide (NiFe₂O₄) nanoparticles are spinel-type ferrite nanomaterials with strong magnetic, catalytic, and electronic properties. Produced at 99% purity, these nanoparticles have an average particle size of 25 nm, a spherical morphology, and a very high specific surface area of 70 m²/g.

NiFe₂O₄ exhibits excellent saturation magnetization (37.2 emu/g) and remanent magnetization (5.5 emu/g), making it a highly efficient material for magnetic recording, shielding, and microwave absorption applications. Combined with its catalytic potential, NiFe₂O₄ is a versatile nanomaterial for both industrial and research applications.
