Nickel Oxide (NiO) Nanopowder Main Feature
Enhanced Reactivity: The nanoscale size of NiO particles results in a high surface area-to-volume ratio, significantly enhancing its reactivity and interaction with other substances. This property is crucial for catalysis, sensor development, and other applications requiring high surface activity.Antiferromagnetic Nature: NiO nanopowder exhibits antiferromagnetic properties at temperatures below its Néel temperature (approximately 523 K). This feature is of interest for magnetic storage media, spintronic devices, and magnetic sensors.Broad Absorption Spectrum: NiO nanopowder has a broad absorption spectrum in the visible to the near-infrared range. This characteristic makes it suitable for photovoltaic applications, photocatalysis, and as a pigment in ceramics and glasses.Corrosion Resistance: NiO is chemically stable and exhibits excellent corrosion resistance against various chemicals, making it suitable for use as a protective layer in corrosion-sensitive applications.P-type Semiconductor: NiO is a p-type semiconductor with a wide bandgap, which is useful in electronic devices, such as transistors and diodes. The nanopowder form can be particularly advantageous for developing thin-film transistors and transparent conducting films.
