Platinum

- 46 percent of the platinum sold in 2010 was used for vehicle emissions control devices such as catalytic converters. - Platinum’s resistance to wear and tarnish is great for making jewelry. - Platinum resistance wires are used in high temperature electric furnaces. - Platinum is used to coat jet engine fuel nozzles and other devices that must operate reliably for long periods of time at high temperatures. - Platinum is used in protection systems to prevent ships and pipelines from corroding in salt water. - Some platinum based agents are used in chemotherapy, and show good activity against some tumors.

Fun Facts

- Platinum was first referenced in 1557 but wasn’t noticed by western scientists until 1735. It was used by pre-Columbian Indians in South America to produce artifacts of a white gold-platinum blend. - In 1741 a British scientist named Charles Wood found samples of platinum in Jamaica, which he sent to scientist William Brownrigg for further investigation. After studying the platinum that was sent to him, in 1750, Brownrigg came out with a detailed account of Platinum. Antonio de Ulloa was also credited with the discovery of platinum and he published a report about platinum in 1748 after an expedition he took to Ecuador, which encouraged many other chemists to study platinum.

-Platinum is a transition metal in group 10 of the periodic table.-Platinum is a soft, dense, malleable metal and it is very resistant to corrosion. It is generally unreactive and considered stable. It is usually silver-white in color.-Platinum can be found free in nature and is sometimes found in deposits of gold bearing sands. It is also still being mined in some places such as the Ural Mountains in Russia. Even though it can be found in nature it is still an extremely rare metal.

Uses

-Platinum is the rarest and heaviest precious metal. All of the platinum ever mined would fit in the average size living room.-When World War 2 began, the U.S. government declared platinum a strategic metal and its use in non-military applications, including jewelry, was not allowed.
