About this deal

are actually adducts of gallium(I) halides with the respective gallium(III) halides, having the structure Ga + Gallium reacts with the chalcogens only at relatively high temperatures. At room temperature, gallium metal is not reactive with air and water because it forms a passive, protective oxide layer. At higher temperatures, however, it reacts with atmospheric oxygen to form gallium(III) oxide, Ga

They also produce less noise than silicon devices, especially at high operating frequencies, making them useful in radars and radio communication devices, satellites and LEDs, Wafer World says.

The metal and its oxides are used in military applications like night-vision devices as well as satellite imagery sensors. Scerri, Eric (2020). The Periodic Table: Its Story and Its Significance. Oxford University Press. p.149. ISBN 978-0-19-091436-3.

The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z. Gallium has no known natural role in biology. Gallium(III) behaves in a similar manner to ferric salts in biological systems and has been used in some medical applications, including pharmaceuticals and radiopharmaceuticals. Preston–Thomas, H.

Electronegativity of Gallium

Extremely high-purity (>99.9999%) gallium is commercially available to serve the semiconductor industry. Gallium arsenide (GaAs) and gallium nitride (GaN) used in electronic components represented about 98% of the gallium consumption in the United States in 2007. About 66% of semiconductor gallium is used in the U.S. in integrated circuits (mostly gallium arsenide), such as the manufacture of ultra-high-speed logic chips and MESFETs for low-noise microwave preamplifiers in cell phones. About 20% of this gallium is used in optoelectronics. [52] During the last few years, specifically 2019 and 2020, a combination of the effects of Covid-19 and delays in mining operations and inspections led to a shortage of bauxite in China. This shortage led to a spike in the price of gallium. The Price of Gallium

Ion source: Gallium is also used as a liquid metal ion source for a focused ion beam. For example, a focused gallium-ion beam was used to create the world's smallest book, Teeny Ted from Turnip Town.

Gallium is produced exclusively as a by-product during the processing of the ores of other metals. Its main source material is bauxite, the chief ore of aluminium, but minor amounts are also extracted from sulfidic zinc ores ( sphalerite being the main host mineral). [58] [59] In the past, certain coals were an important source. GaCl can also be produced by reacting Ga with HCl at 950°C; the product can be condensed as a red solid. [29] :1036 The United States Geological Survey (USGS) estimates that more than 1million tons of gallium is contained in known reserves of bauxite and zinc ores. [52] [53] Some coal flue dusts contain small quantities of gallium, typically less than 1% by weight. [54] [55] [56] [57] However, these amounts are not extractable without mining of the host materials (see below). Thus, the availability of gallium is fundamentally determined by the rate at which bauxite, zinc ores, and coal are extracted.
