Description

Iron Oxide (Fe₂O₃) Micron Powder, Gamma, Purity: 99.9+%, Size: 1 µm

Product Description:
Iron Oxide (Fe₂O₃) Micron Powder in the gamma phase is a highly pure and ultrafine material engineered for advanced technological and industrial applications. With a particle size of 1 µm and purity exceeding 99.9%, this powder exhibits exceptional surface area, magnetic response, and chemical reactivity, distinguishing it from its alpha counterpart (hematite).

Gamma-Fe₂O₃, also known as maghemite, features ferrimagnetic properties, making it a prime candidate for use in magnetic storage systems, spintronic devices, and ferrofluids. Its fine grain size and uniform morphology enhance its performance in high-resolution coatings, biomedical applications, and electronic components.

Due to its non-toxic and biocompatible nature, this iron oxide form is widely utilized in MRI contrast agents, targeted drug delivery, and magnetic hyperthermia for cancer treatment. Its excellent catalytic activity supports its role in environmental remediation, photocatalysis, and chemical vapor deposition processes.

Gamma iron oxide also demonstrates strong light absorption and thermal insulation properties, making it useful in infrared shielding, UV-resistant paints, and pigment-based formulations for plastics and ceramics.
