Description
Antimony Oxide (Sb₂O₃) Nanopowder / Nanoparticles (99.8+%, 400 nm)
Antimony Oxide (Sb₂O₃) Nanopowder is a high-purity white nanomaterial with a purity of 99.8+% and an average particle size of 400 nm. Known for its orthorhombic crystal structure, relatively low melting point (660 °C), and stable chemical properties, Sb₂O₃ nanoparticles are valued in multiple industries. The material features a specific surface area greater than 10 m²/g and excellent dispersibility, making it suitable for advanced optical, electronic, catalytic, and flame-retardant applications.
Antimony oxide nanoparticles are especially significant in the electronics sector as a doped material, while also serving as a reliable flame retardant and filler in polymers, coatings, and composites. Their high refractive index also makes them useful in optical and ceramic applications.
