Gallium has a similar dissolved profile similar to that of aluminium, due to this gallium can be used as a tracer for aluminium. [110] Gallium can also be used as a tracer of aeolian inputs of iron. [111] Gallium is used as a tracer for iron in the northwest Pacific, south and central Atlantic Oceans. [111]
It was apparently discovered by the fictional Thomas Kyle, who was awarded an Ig Nobel Prize for physics for his discovery, [10] and it is a parody on bureaucracy of scientific establishments and on descriptions of newly discovered chemical elements. Administrontium Scientific in-joke: Similar to Administratium and a variation of the joke. It ...
The chemical elements were discovered in identified minerals and with the help of the identified elements the mineral crystal structure could be described. One milestone was the discovery of the geometrical law of crystallization by René Just Haüy , a further development of the work by Nicolas Steno and Jean-Baptiste L. Romé de l'Isle (the ...
Thallium, the heaviest stable element in the boron group, was discovered by William Crookes and Claude-Auguste Lamy in 1861. Unlike gallium and indium, thallium had not been predicted by Dmitri Mendeleev, having been discovered before Mendeleev invented the periodic table. As a result, no one was really looking for it until the 1850s when ...
Bauxite is the main source of the rare metal gallium. [17] During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin. [18]
Also called TEGa, it is a metalorganic source of gallium for metalorganic vapour phase epitaxy (MOVPE) of compound semiconductors. It is a colorless pyrophoric liquid, [2] typically handled with air-free techniques. It was discovered by Cornell University chemists L. M. Dennis and Winton Patnode in 1931. [3]
Thulium is from the Ancient Greek word for the remote Arctic land that the Romans called ultima Thule. [24] [28] A number of other elements are named after classical words for various places. Ruthenium is from the Latin name for the region including Belarus, Ukraine, and Russia. [29] Lutetium is named after Lutetia, the Latin name for Paris.
However, due to its variable trace element content, sphalerite is also an important source of several other metals such as cadmium, [43] gallium, [44] germanium, [45] and indium [46] which replace zinc. The ore was originally called blende by miners (from German blind or deceiving) because it resembles galena but yields no lead. [21]
