Description
Tungsten Oxide (WO₃) Nanopowder / Nanoparticles (99.99%, 55 nm, Tetragonal)
Tungsten Oxide (WO₃) Nanoparticles are advanced functional nanomaterials with a high purity of 99.99% and an average particle size of ~55 nm. With a tetragonal crystalline structure and nearly spherical morphology, WO₃ nanomaterials are valued for their unique optical, catalytic, electronic, and sensing properties.
These nanoparticles are widely applied in gas sensors, smart windows, infrared devices, and energy systems, as well as in ceramic pigments and catalysts. Their stability, fine particle distribution, and exceptional purity make them ideal for both industrial and research applications.
