Descripción general

Gold(Au) is a yellow noble metal known for its lustrous appearance and highresistance to corrosion. With a melting point of 1,063 °C, gold is one of themost malleable and ductile metals, making it ideal for various applications.Our high-purity gold powder is characterized by its purity of 99.9% on a tracemetals basis and is available in a fine powder form with particle sizes <10μm. Gold is widely used in electronics, dental materials, and as a catalyst invarious chemical reactions. Gold powder is a key material in the synthesisof gold nanoparticles, which have applications in sensors, imaging, and ascomponents in nanocomposites. The unique optical properties of goldnanoparticles are exploited in various nanotechnology applications.[1][2][3]
