General description
Gold (Au) is a yellow noble metal known for its lustrous appearance and high resistance to corrosion. With a melting point of 1,063 °C, gold is one of the most malleable and ductile metals, making it ideal for various applications. Our high-purity gold powder is characterized by its purity of 99.995% on a trace metals basis and is available in a fine powder form with particle sizes less than 45 microns. Gold is widely used in electronics, dental materials, and as a catalyst in various chemical reactions. Its exceptional conductivity and biocompatibility make it particularly valuable in electronics, catalysis, and synthesis.
Application
Applied in the synthesis of new low-dimensional, quaternary gold selenophosphate compounds, A3AuP2Se8 (a=Rb, K, Cs) and A2Au2P2Se6 (a=Rb, K).

Multifunctional phosphine based ligands, 1,1,1-tris(diphenylphosphinomethyl)ethane [CH3C(CH2 PPh2)3][P3] and 1,1,1-tris(diphenylphosphinomethyl)ethane trisulphide [CH3C(CH2P(S)Ph2)3][P3S3] have been introduced to stabilize Au(o)-nanoparticles having small core diameter and narrow size distribution. The Au(o)-nanoparticles were synthesized by the reduction of HAuCl4 precursor with NaBH4 in the presence
