The Element Gallium

In 1871, Dmitri Mendeleyev first proposed the existence of gallium based on his newly created periodic table gap, and in 1875 France chemist Paul - Emile Lecoqde Boisbaudran found gallium. In the second half of that year, Lecoq got a solution of pure gallium by electrolysis of gallium hydroxide (Ga (OH) 3) in potassium hydroxide (KOH).

Gallium melted at around room temperature and has one of the largest liquid ranges among all metals, so it has been used for high temperature thermometers. Gallium is easily alloyed with most metals and has been used for the manufacture of low melting point alloys. Gallium is used as a semiconductor doping material and has been used to manufacture solid products such as transistors and light emitting diodes. Gallium arsenide (GaAs) produces laser light directly from electricity. A large amount of gallium trichloride (GaCl 3) is collected to form a gallium neutrino observatory, an Italian observatory that studies particles called neutrinos generated inside the sun during nuclear fusion.

Gallium element is not found naturally, but it is easily obtained by smelting. Very pure gallium metal has a silver color and its solid metal cracks are like glass. After solidification, the gallium solution expands 1%, so do not store in a glass or metal container as it may rupture when the state of gallium changes. Gallium shares a denser liquid with a short list of other materials including water, silicon, germanium, germanium, germanium and germanium.

In nature, gallium has never been discovered as a free element and can not exist in large quantities in any minerals. Instead, it is present in trace amounts of various compounds including zinc ore and bauxite. According to data from PeriodicTable.com, gallium accounts for about 0.0019% by weight of the Earth's crust. However, according to Chemicool, it is easily obtained by smelting and most commercially available gallium is extracted as a by-product of aluminum and zinc production. The largest gallium producing countries are Australia, Russia, France and Germany.

Lecoq de Boisbaudran wondered if element 31 could be found in a zinc mine. Zinc of atomic number 30 is next to gallium in the periodic table. With the beam splitter in August 1875, Lecoq de Boisbaudran found some gallium, but only a little. According to Chemistry Explained, he reports that the spectrum of the new element consists of narrow and easy-to-see ultraviolet rays. In the second half of that year, according to Jefferson's laboratory, Lecoq de Boisbaudran gained pure gallium by electrolyzing gallium hydroxide in potassium hydroxide. Lecoq de Boisbaudran was later provided with a large amount of zinc mine from miners for his research. According to Chemistry Explained, from this ore, he was able to produce several grams of nearly pure gallium. Lecoq de Boisbaudran proposes the name gallium as a new element. It comes from the Latin "Gallia" and means France
