Platinum is one of nine precious metals on the periodic table. It has a melting point of 1,772°C, a density of 21.4 g/cc, and vapor pressure of 10-4 Torr at 1,747°C. It is a radiant, silvery-white metal that bears a striking resemblance to palladium. It is dense, malleable, ductile, and corrosion resistant in air. Its most prominent commercial application is as a catalytic converter in vehicles. Platinum is evaporated under vacuum for the manufacture of semiconductors, fuel cells, and batteries. It is also utilized as a layer for optical coatings. Platinum is commonly found in jewelry and laboratory instruments.

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.
