Gold is one of the more beautiful precious metals with a lustrous, yellow sheen. It has a melting point of 1,064°C, a density of 19.3 g/cc, and a vapor pressure of 10-4 Torr at 1,132°C with its ideal evaporation temperature being around 1,400°C. It is soft, dense, malleable, ductile, and an excellent conductor of heat and electricity. Deposited films of gold are used as layers in the production of semiconductors, sensors, batteries, and data storage.
Stanford Advanced Materials (SAM) is a leading manufacturer and supplier of high purity Gold Evaporation Materials and a wide variety of evaporation materials. We offer our evaporation materials in powder and granule form. Customized forms are also available upon request.
High purity evaporation materials play a huge role in deposition processes to ensure high quality deposited film. Stanford Advanced Materials (SAM) specializes in producing up to 99.99% purity gold evaporation materials using quality assurance processes to guarantee product reliability.
• Used in deposition processes including semiconductor deposition, chemical vapor deposition (CVD) and physical vapor deposition (PVD)
• Used for optics including wear protection, decorative coatings, and displays.
Our evaporation materials are carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
