Paul-Émile Lecoq de Boisbaudran/Discovered
Paul-Émile Lecoq de Boisbaudran, (born April 18, 1838, Cognac, Fr. —died May 28, 1912, Paris), French chemist who developed improved spectroscopic techniques for chemical analysis and discovered the elements gallium (1875), samarium (1880), and dysprosium (1886).
How did Paul Emile Lecoq de Boisbaudran discovered gallium?
The French chemist Paul-Emile Lecoq de Boisbaudran discovered gallium in sphalerite (a zinc-sulfide mineral) in 1875 using spectroscopy. Because of these properties, the earliest uses of gallium were in high-temperature thermometers and in designing metal alloys that melt easily.
How did Lecoq discover gallium?
A significant achievement of Lecoq de Boisbaudran was his discovery of the element gallium in 1875. Beginning in 1874, Lecoq de Boisbaudran investigated a sample of 52 kg of the mineral ore sphalerite obtained from the Pierrefitte mine in the Pyrenees. From it, he extracted several milligrams of gallium chloride.
What is dysprosium found in?
1886
Dysprosium/Discovered
What are uses of gallium?
Gallium is a soft, silvery metal used primarily in electronic circuits, semiconductors and light-emitting diodes (LEDs). It is also useful in high-temperature thermometers, barometers, pharmaceuticals and nuclear medicine tests. The element has no known biological value.
What is eka aluminium?
Eka aluminum is the element Gallium. Eka silicon – It is the element Germanium.
What is gallium used for in everyday life?
Gallium is a soft, silvery metal used primarily in electronic circuits, semiconductors and light-emitting diodes (LEDs). It is also useful in high-temperature thermometers, barometers, pharmaceuticals and nuclear medicine tests.
Is dysprosium man made?
Dysprosium is never found in nature as a free element, though it is found in various minerals, such as xenotime. Naturally occurring dysprosium is composed of seven isotopes, the most abundant of which is 164Dy.
