Description
Chromium (Cr) Nanopowder / Nanoparticles – 99.9% Purity, 35–45 nm, Metal Basis
Chromium (Cr) Nanopowder is a high-purity (99.9% metal basis) ultra-fine metallic powder produced by the electrical explosion method, ensuring very low oxygen content and high reactivity. With an average particle size (APS) of 35–45 nm and a specific surface area of 20–30 m²/g, these spherical black nanoparticles exhibit excellent dispersion and chemical stability.
Due to their hardness, corrosion resistance, and wear resistance, Chromium Nanoparticles are widely used in metal-ceramic production, hard alloys, diamond tools, and advanced coating technologies. Their unique nanoscale properties enable superior performance in both industrial and research applications.
