Description

Iron Oxide (Fe₂O₃) Micron Powder, Gamma, Purity: 99.9+%, Size: -325 mesh

Product Description:
Iron Oxide (Fe₂O₃) Micron Powder in its gamma crystalline phase is a high-purity, fine-grained material with unique magnetic and electronic properties. With a particle size of -325 mesh and purity greater than 99.9%, this form of iron oxide is widely used in advanced material science, electronics, catalysis, and magnetic applications.

Unlike the more stable alpha phase (hematite), gamma-phase Fe₂O₃ (also known as maghemite) possesses ferrimagnetic properties, making it ideal for use in magnetic storage media, data recording devices, and ferrofluids. Its high surface area and reactive surface chemistry also make it an effective catalyst and catalyst support in chemical synthesis and gas-phase reactions.

Due to its non-toxic and environmentally benign nature, gamma iron oxide is commonly used in biomedical applications such as magnetic resonance imaging (MRI) contrast agents, targeted drug delivery systems, and hyperthermia treatment for cancer. Its fine particle size and consistent distribution enhance performance in pigments for coatings, ceramics, and polishing agents.

Gamma Fe₂O₃ exhibits strong UV absorption and infrared reflectivity, making it suitable for UV-blocking and thermal shielding materials. It also finds application in electromagnetic shielding, battery electrodes, and sensor fabrication.
