Description

Description générale

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).
