Platinum is widely used as a catalyst. In past several years platinum has become a very precious metal. Platinum is also used in autocatalysts. Most popular in China, platinum jewellery is generally purer than its gold counterpart, because the metal is denser (21.5 grams per cubic centimetre versus 19.3 g/cm3) and more hard-wearing. Platinum is used extensively for jewelry, manufactured into metal gauzes for nitric acid production and as a catalyst to improve the efficiency of fuel cells. In 1780, it was being used in France to make crucibles for glass production, a use that, to this day, consumes tens of thousands of ounces of platinum each year. It is also used in coins and to make jewelry such as rings, earrings, and watches. Palladium is not tarnished by the atmosphere at ordinary temperatures. Being a precious metal, platinum is often used as currency and as an investment. It is more precious than gold and silver. The use of platinum for the manufacture of crucibles was established some time before the end of the eighteenth century, and such crucibles, together with other apparatus fabricated in platinum, became an essential requirement for accurate chemical analysis. Platinum is also used in a device called a catalytic converter, a device found in the exhaust systems of most cars. Platinum is widely considered the most practical of the precious metals, and it has been used industrially since the time of the ancient Egyptians for fashioning fine items. These and other main usage areas are … Investments. 5 Common Uses Jewelery. I would be delighted to receive corrections as well as additional referenced uses..

Some of these include catalysts for automotive and chemical applications, glass manufacture and electronics. This effect is used to make small hand warmers. It is used as a catalyst for the automobile and petroleum industries. Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.
Platinum is an expensive metal, even more so than gold, and this does limit its use. Some examples of end-use applications include: as catalysts for the petroleum industry (palladium and platinum), in pacemakers and other medical implants (iridium and platinum), as a stain for fingerprints and DNA (osmium), in the production of nitric acid (rhodium), and in chemicals, such as cleaning liquids, adhesives, and paints (ruthenium).
