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.
