Silver is a soft, lustrous element that belongs to the transition group of metals on the periodic table. It has a melting point of 962°C, a density of 10.5 g/cc, and vapor pressure of 10-4 Torr at 1,105°C. Silver has been used since ancient times in countless products. It is ductile, malleable, and the most electrically conductive of all metals. It is considered a precious metal and can be found in jewelry, solders, paints, and mirrors. It is evaporated under vacuum for the production of semiconductors, sensors, fuel cells, and optical coatings.

Vacuum evaporation means the evaporation materials are evaporated to atoms or molecules in vacuum by current heating, electron beam heating and laser heating. Atoms or molecules make rectilinear motion to impact substrate surface and condense to form films.
