Platinum is sometimes used in applications like jewelry and in the laboratory for chemical resistance, but along with palladium and rhodium is most often used industrially in catalysts. It is acommon ingredient in catalytic converters used to reduce emissions from cars and trucks. It also finds utility in hydrogenation processes, a common procedure in processing fats and vegetable oils, as well as petroleum and some synthetic chemicals.
Platinum is a commodity traded on world markets.
