Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury Basin is one such example. Heating this ammonium salt in the presence of hydrogen reduces it to elemental platinum. [36], Several barium platinides have been synthesized in which platinum exhibits negative oxidation states ranging from −1 to −2. [70], Platinum is a precious metal commodity; its bullion has the ISO currency code of XPT. Platinum-cobalt, an alloy of roughly three parts platinum and one part cobalt, is used to make relatively strong permanent magnets. Its most important application is in automobiles as a catalytic converter, which allows the complete combustion of low concentrations of unburned hydrocarbons from the exhaust into carbon dioxide and water vapor.

Until May 2019, the kilogram was defined as the mass of the international prototype of the kilogram, a cylinder of the same platinum-iridium alloy made in 1879.[67]. The Standard Platinum Resistance Thermometer (SPRT) is one of the four types of thermometers used to define the International Temperature Scale of 1990 (ITS-90), the international calibration standard for temperature measurements. This started what is known as the "platinum age" in Spain. Silver is a popular precious metal for jewelry, but its value extends well beyond beauty. The remaining 28.9 tonnes went to various other minor applications, such as medicine and biomedicine, glassmaking equipment, investment, electrodes, anticancer drugs, oxygen sensors, spark plugs and turbine engines. [49][50] The platinum used in such objects was not the pure element, but rather a naturally occurring mixture of the platinum group metals, with small amounts of palladium, rhodium, and iridium. [10][11] The metal has excellent resistance to corrosion, is stable at high temperatures and has stable electrical properties. [73], During periods of sustained economic stability and growth, the price of platinum tends to be as much as twice the price of gold, whereas during periods of economic uncertainty,[74] the price of platinum tends to decrease due to reduced industrial demand, falling below the price of gold. Natural Platinum is fairly impure. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity.[5]. [52], Platinum, along with the rest of the platinum-group metals, is obtained commercially as a by-product from nickel and copper mining and processing. Rare Platinum by Avon is a Floral Fruity fragrance for women. Antonio de Ulloa returned to Spain and established the first mineralogy lab in Spain and was the first to systematically study platinum, which was in 1748.

Most platinum isotopes decay by some combination of beta decay and alpha decay. [56], In 1786, Charles III of Spain provided a library and laboratory to Pierre-François Chabaneau to aid in his research of platinum. Of the naturally occurring isotopes, only 190Pt is unstable, though it decays with a half-life of 6.5×1011 years, causing an activity of 15 Bq/kg of natural platinum. [32] Platinum also strongly catalyzes the decomposition of hydrogen peroxide into water and oxygen[64] and it is used in fuel cells[65] as a catalyst for the reduction of oxygen. Being a heavy metal, it leads to health problems upon exposure to its salts; but due to its corrosion resistance, metallic platinum has not been linked to adverse health effects. Platinum mining is also far less efficient than gold mining. [7], As of 2020, the value of platinum is around $32.00 per gram ($1,000 per troy ounce). It is quite possible they did not recognize there was platinum in their gold.

More precious than gold, natural platinum nuggets are extremely rare and hard to obtain. Due to its rarity and value, it is not readily available to mineral collectors and is seldom represented in in all but the highest-end mineral collections. Archeologists usually associate the tradition of platinum-working in South America with the La Tolita Culture (circa 600 BC - AD 200), but precise dates and location is difficult, as most platinum artifacts from the area were bought secondhand through the antiquities trade rather than obtained by direct archeological excavation. To put it in perspective, each year there is fifteen times more gold mined than platinum. Platinum had a major price drop at the onset of the 2008 financial crisis. It is the only stable isotope with a non-zero spin; with a spin of 1/2, 195Pt satellite peaks are often observed in 1H and 31P NMR spectroscopy (i.e., Pt-phosphine and Pt-alkyl complexes). It was often simply thrown away, and there was an official decree forbidding the adulteration of gold with platinum impurities. [41] Others include carboplatin and oxaliplatin. [15] Its resistance to wear and tarnish is well suited to use in fine jewellery. Platinum hexafluoride is a strong oxidizer capable of oxidizing oxygen. Their assumptions could not be avoided because the platinum they experimented with was highly contaminated with minute amounts of platinum-family elements such as osmium and iridium, amongst others, which embrittled the platinum alloy. Where are all the Rare Candies in Platinum? In 1758, he was sent to superintend mercury mining operations in Huancavelica.[52]. Finally, platinum is resistant to hydrochloric and sulfuric acids, whereas other substances are readily attacked by them. Although gold is also used in industrial applications, especially in electronics due to its use as a conductor, its demand is not so driven by industrial uses. It is used for this purpose for its prestige and inherent bullion value. How are Coin Designs Chosen for the America the Beautiful Coins? [52] From their first encounters with platinum, the Spanish generally saw the metal as a kind of impurity in gold, and it was treated as such. (For information about the mining, recovery, and production of platinum, see platinum processing.) It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that it began to be investigated by scientists. [51], The first European reference to platinum appears in 1557 in the writings of the Italian humanist Julius Caesar Scaliger as a description of an unknown noble metal found between Darién and Mexico, "which no fire nor any Spanish artifice has yet been able to liquefy".
