The most important use of platinum is in vehicles, as a catalytic converter, facilitating the complete combustion of unburned hydrocarbon passing through the exhaust. Platinum is also used as a catalyst to make chemicals like silicone, nitric acid and benzene. ; Silicones – Adding platinum compounds controls curing, helping to achieve the properties required for the numerous uses they have in everyday life. Coronary stents, heart valve splices, and pacemaker components are all made with platinum. Because of its stable physical and chemical properties, platinum metal is a very useful metal. Platinum is an important catalyst in many chemical processes and nitric acid, fertilizers and synthetic fibers all require platinum to be produced. It is more precious than gold and silver. Platinum is used as an alloying agent for various metal products, including fine wires, noncorrosive laboratory containers, medical instruments, dental prostheses, electrical contacts, and thermocouples. Research into the use of platinum shows that technological advances are needed before it can match the performance of existing palladium-based catalytic converters, according to … Platinum-cobalt, an alloy of roughly three parts platinum and one part cobalt, is used to make relatively strong permanent magnets. Platinum is also used in autocatalysts. Nitric Acid – Platinum-based catalysts have now been used in the commercial manufacture of nitric acid for a century. Because of its high stability, platinum is used extensively as … Platinum is a dense, stable and rare metal that is often used in jewelry for its attractive, silver-like appearance, as well as in medical, electronic, and chemical applications due to its various and unique chemical and physical properties. The platinum coats the autocatalysts which is designed to chemically control the harmful emissons that your vehicle makes. Platinum engagement rings, wedding bands, necklaces and bracelets account for over a third of the metal's use each year, almost as much as in autocats. Platinum guidewires are used to maneuver catheters to treatment sites.
