Platinum (Lat. Platinum) is an element in the group of rare metals. It has an atomic number of 78 and an atomic mass of 195.09. This metal is malleable, ductile, and can be easily stamped and rolled. Platinum has a melting temperature of 1769°C and a boiling point of 4300°C. Platinum typically contains up to 35% impurities of palladium, iron, iridium, osmium, copper, nickel, radium, and gold.
Electrically conductive, chemically inert, and corrosion-resistant, platinum metal is widely used in various areas of industrial production. Relatively large amounts of platinum are found in automotive catalytic converters. The amount of platinum in these parts ranges from about 3-7 grams per catalyst. Although platinum is often used in the manufacture of various electronic devices, the amount of precious metal contained in these devices is so small that the retail extraction of platinum from these devices is considered to be a completely economically unviable process.
Platinum and its alloys are used to make tableware, various appliances, electrodes and electronic contacts, thermometers and thermocouples, and surgical instruments that are resistant to corrosion and chemical reactions. In medicine, platinum is also used as an alloy in the manufacture of dental materials and biomedical devices (such as stents and pacemakers). In the glass industry, platinum-rhodium alloys are used to coat glass-making equipment to protect it from highly corrosive molten glass. This process is widely used in the production of fibreglass and high-quality flat glass used in television and telephone screens. Because of its exceptional appearance and rarity, platinum is also extensively used in the manufacture of jewellery and investment bars.
