Fields of Application of Gallium

Gallium arsenide in LED

Electric cars, flat screens, displays, room lighting, traffic light systems; the range of applications of light-emitting diodes is impressive. Gallium nitride (GaN) is processed in each layer of an LED. The raw material makes it possible for the diodes to glow in all colours.

Photovoltaics and Gallium Arsenide

The gallium-arsenide semiconductor compound is used for thin-film solar cells as a replacement for the more common silicon. Gallium makes the solar cells more heat-resistant and light-sensitive. However, due to the high costs, it is mainly used in special projects; such as space travel.

Gallium in Computer Electronics

Gallium arsenide wafers make computer chips more heat-resistant, faster and save power. Due to its special chemical properties, gallium is also used in liquid metal thermal pastes for cooling electronic components.


Gallium was discovered in 1875 by the French chemist Paul-Emile Lecoq de Boisbaudran. Boisbaudran had been active in the family wine trade since 1858. In his spare time, however, he devoted himself to the search for new elements, which he hoped to find by means of spectroscopic analysis. In the year 1869 Dmitry Ivanovich Mendeleyev published the periodic table. On it he had left some places vacant, but had nevertheless made assumptions about the properties of the elements he suspected to be there. One of the elements whose existence Mendeleyev had logically developed was Eka aluminium.

Six years later Boisbaudran notices the spectral lines of another element during the analysis of zinc sulphite. It has, as the chemist notes after the insulation, the same properties that Mendeleyev had already predicted for the Eka aluminium. Boisbaudran’s discovery cements the belief in the correctness of the periodic table.

Paul-Emile Lecoq de Boisbaudran

The Frenchman calls his discovery Gallium, after his native France, which is called Gaul in Latin. Boisbaudran may however also have placed a monument to his last name in the element, because Lecoq means rooster, and this in Latin is called Gallus.
