How rizal overcome frustrations in his romances? Home. 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. Platinum is also used in the petroleum industry as a catalyst in a number of separate processes, but especially in catalytic reforming of straight-run naphthas into higher-octane gasoline that becomes rich in aromatic compounds. See the popularity of the girl's name Platinum over time, plus its meaning, origin, common sibling names, and more in BabyCenter's Baby Names tool. It was often simply thrown away, and there was an official decree forbidding the adulteration of gold with platinum impurities. Sometimes the metal was entirely incombustible, but when alloyed with osmium, it would volatilize.

Platinum-cobalt, an alloy of roughly three parts platinum and one part cobalt, is used to make relatively strong permanent magnets. Metal impurities can be removed by stirring the mixture in either of the two acids and recovering the remaining platinum. [32], Treatment of hexachloroplatinic acid with an ammonium salt, such as ammonium chloride, gives ammonium hexachloroplatinate,[16] which is relatively insoluble in ammonium solutions. platinum sur l’encyclopédie Wikipédia (en anglais) Mannois [modifier le wikicode] Étymologie [modifier le wikicode] (Date à préciser) De l'espagnol platina et du suffixe nominal latin -um.

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]. [36], Several barium platinides have been synthesized in which platinum exhibits negative oxidation states ranging from −1 to −2. PtBiTe), antimonides (PdSb), and arsenides (e.g. The Latin name for silver, ‘argentum’, is thought to derive originally from an Indo-European language, likely referring to the metal’s shininess. [9] Platinum is more ductile than gold, silver or copper, thus being the most ductile of pure metals, but it is less malleable than gold. Back to Top. Its name is derived from the Spanish term platino, meaning "little silver". In 1752, Henrik Scheffer published a detailed scientific description of the metal, which he referred to as "white gold", including an account of how he succeeded in fusing platinum ore with the aid of arsenic. \ Platine. Platinum arsenide, sperrylite (PtAs2), is a major source of platinum associated with nickel ores in the Sudbury Basin deposit in Ontario, Canada.

Most often the native platinum is found in secondary deposits in alluvial deposits. [52], Because the other platinum-family members were not discovered yet (platinum was the first in the list), Scheffer and Sickingen made the false assumption that due to its hardness—which is slightly more than for pure iron—platinum would be a relatively non-pliable material, even brittle at times, when in fact its ductility and malleability are close to that of gold. metallic element, 1812, Modern Latin, altered from earlier platina, from Spanish platina "platinum," diminutive of plata "silver," from Old French plate or Old Provençal plata "sheet of metal" (see plate (n.)).

What are the Latin Names of Chemical Elements? Where is the name Platinum popular? Pt. In the 18th century, platinum's rarity made King Louis XV of France declare it the only metal fit for a king. Parcourir mots et des phrases milions dans toutes les langues. The standard hydrogen electrode also uses a platinized platinum electrode due to its corrosion resistance, and other attributes. An atom of an element is denoted by this symbol. The most common oxidation states of platinum are +2 and +4. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. 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. Platinum is often found chemically uncombined as native platinum and as alloy with the other platinum-group metals and iron mostly. These include BaPt, Ba3Pt2, and Ba2Pt. 2.1. platinum colour: 3.

Ammonium chloroplatinate can be converted to platinum by heating. aurum. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. [15] Its resistance to wear and tarnish is well suited to use in fine jewellery. This started what is known as the "platinum age" in Spain. In 1741, Charles Wood,[53] a British metallurgist, found various samples of Colombian platinum in Jamaica, which he sent to William Brownrigg for further investigation. Each element has a chemical symbol that is unique to it. 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. [9] Platinum(II,IV) oxide, Pt3O4, is formed in the following reaction: Unlike palladium acetate, platinum(II) acetate is not commercially available. 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. [39] Platinum also exhibits negative oxidation states at surfaces reduced electrochemically. Alloying this impure platinum residue called "plyoxen" with gold was the only solution at the time to obtain a pliable compound, but nowadays, very pure platinum is available and extremely long wires can be drawn from pure platinum, very easily, due to its crystalline structure, which is similar to that of many soft metals.
