Wollaston, William Hyde

Wollaston, William Hyde (1766-1828) was an English scientist who discovered Pd in 1803 and named it after the asteroid Pallas, found in 1802. The mineral wollastonite is named after him. [Pg.688]

William Hyde Wollaston (1766-1828) found rhodium in crude platinum. [Pg.57]

Rhodium (Rh, [Kr]4t/x5v1), name from the Greek po ov (rhodon rose). Discovered (1803) by the English chemist William Hyde Wollaston. [Pg.431]

Rhodium - the atomic number is 45 and the chemical symbol is Rh. The name derives from the Greek rhodon for rose because of the rose color of dilute solutions of its salts . It was discovered by the English chemist and physicist William Hyde Wollaston in 1803 in a crude platinum ore. [Pg.18]

The story became more complicated when in 1809 the Enghsh scientist William Hyde Wollaston (1766—1828) analyzed the sample mineral and declared that columbium was really the same element as tantalum ( Ta). This error is understandable given that the level of analytical equipment available to scientists in those days was fairly primitive. Also, tantalum and niobium are very similar metals that are usually found together and thus are difficult to separate for analysis. [Pg.126]

William Hyde Wollaston (1766—1828), who had also discovered palladium (4gPd) in the early 1800s, announced in 1803 his discovery of another metal that he had isolated... [Pg.136]

In 1803 William Hyde Wollaston, a British physician who became famous for his research in metallurgy, mineralogy, and optics, succeeded in extracting a white metal from platinum. He named the new element palladium, after the asteroid Pallas, which had just been discovered the previous year. In the same year the English chemist Smithson Tennant obtained two new metals, which he named iridium and osmium, from platinum. And in 1828 the Russian chemist Karl Karlovich Klaus reported that he had obtained three new metals from platinum mined in the Urals. However, the existence of only one of them, which Klaus called ruthenium, was confirmed. [Pg.80]

British scientist William Hyde Wollaston Hard, anticorrosive metal whose salts have a red color, its name is derived from the Greek word for red used in automotive catalytic converters. [Pg.237]

British scientist William Hyde Wollaston Anticorrosive, soft metal often found combined with platinum useful in dentistry, as a cancer-fighting agent easily absorbs hydrogen and used as a purifier of that gas. [Pg.237]

Sir Walter Scott, 1771-1832. Scottish novelist and poet. His writings contain many interesting allusions to his uncle, Dr. Daniel Rutherford. Scott s circle of friends included Dr William Hyde Wollaston, Sir David Brewster, Dr. John Davy, Sir Humphry Davy, and Joseph Black. [Pg.239]

William Hyde Wollaston, the son of an Episcopal clergyman, was bom as East Dereham, Norfolkshire, England, on August 6, 1766. His childhood was not a lonely one, for he had fourteen active brothers and sisters. After studying at Cambridge, he received his medical degree at... [Pg.423]

Birth of Dr. William Hyde Wollaston, the discoverer of palladium and rhodium, at East Dereham, Norfolkshire. [Pg.889]

When palladium was first discovered, no one seemed to want it. Its discoverer, William Hyde Wollaston, offered it for sale in a London shop as new silver , at six times the price of gold. Hoping to profit from his discovery, at first he chose not to disclose to the scientific... [Pg.146]

William Hyde Wollaston, On Super-Acid and Sub-Acid Salts, Phil Trans. 98 (1808) 96-102. Quoted in Henry M. Leicester and Herbert S. Klickstein, A Source Book in Chemistry 1400-ipoo (New York McGraw-Hill, 1952), 221-222. [Pg.253]

At the start of the nineteenth century, platinum was refined in a scientific manner by William Hyde Wollaston, resulting in the successful production of malleable platinum on a commercial scale. During the course of the analytical work, Wollaston discovered palladium, rhodium, iridium, and osmium. Ruthenium was not discovered until 1844, when work was conducted on the composition of platinum ores from the Ural Mountains. [Pg.162]

Although platinum was introduced to Europe in the mid-18th century, it was first made commercially available in large quantities and in malleable form in 1805 by the English chemist William Hyde Wollaston. Previous attempts at consistently producing malleable metal were hindered by chemical purification techniques that gave platinum contaminated with deleterious metallic impurities. Richard KnighPs improved process of 1800 was carried out on a suitable sample of crude ore, and analysis of the purified platinum by spark source mass spectrometry (SSMS) indicates an impurity level of about 6%. Reconstruction of Wollaston s purification procedures, coupled with SSMS analysis, indicates that his product was over 98% pure. His superior chemical purification techniques, coupled with improvements in the powder consolidation method, explain Wollastons success. [Pg.295]
