2017年12月1日 · Gallium (Ga) is extensively employed in integrated circuits and advanced electronic devices as it provides the benefits of low energy consumption and high computation speeds. However, the Ga-bearing host minerals are scarce in nature.

2021年9月10日 · Gallium exhibits weak metallic properties owing to its proximity to non-metals in the periodic table, yet is volatile in extra-terrestrial bodies and fairly reactive in nature. It has been used extensively to elucidate the Solar System evolution, planet interior differentiation, and terrestrial processes.

2018年1月1日 · Gallium is a moderately volatile element during gas to solid or gas to liquid condensation or evaporation processes occurring in the solar nebula. While pure Ga metal has a high boiling point (2,400 °C), Ga forms volatile chlorides in a gas of solar composition.

Gallium has stronger acidic properties, so that Ga (OH) 3 precipitates at pH 3.4 compared to Al (OH) 3 at pH 4.1. The stronger Ga–S bond enables the formation of stable sulfides. Gallium also tends to form organometallic complexes, unlike aluminum. The geochemical coherency of gallium and aluminum is very high.

About 79% of gallium consumed in the United States is in the form of gallium arsenide (GaAs), gallium nitride (GaN), and gallium phosphide (GaP) wafers. Gallium consumed in the epitaxial layering process to fabricate epiwafers accounted for most of the remainder.

Gallium (Ga) concentrations for bauxite deposits worldwide have been compiled from the literature to provide a basis for research regarding the occurrence and distribution of Ga worldwide, as well as between types of bauxite deposits.

2006年1月1日 · Solubilities of α-GaOOH (s) and GeO 2 (tetragonal) have been estimated up to 300 °C and both increase with increasing temperature. The solubility of pure α-GaOOH (s) at 25 °C (< 10 −6 m) is quite low from pH 3 to pH 8, consistent with the general immobility of Ga in the weathering environment and its concentration in bauxites. 1. Introduction.

Gallium nitride (GaN) is used as a semiconductor in the manufacture of LED electroluminescent diodes for lighting vehicles, buses, trains, airplanes, traffic lights, buildings, and homes across entire cities, with significant savings in energy consumption without sacrificing the quality and intensity of incandescent or fluorescent lamps.

2013年7月14日 · What is Gallium? Gallium is a soft, silvery white metal with a melting point similar to chocolate; it melts in your hand. Gallium is used in low-melting-point alloys, but its’ main use is in gallium nitride semiconductors, key components of many high-tech devices such as cell phones, LEDs, switches, fiber optic cables, solar panels, and many ...

2013年3月26日 · Gallium is a soft, silvery metallic element with an atomic number of 31 and the chemical symbol Ga. The French chemist Paul-Emile Lecoq de Boisbaudran discovered gallium in sphalerite (a zinc-sulfide mineral) in 1875 using spectroscopy. He named the element "gallia" after his native land of France (formerly Gaul; in Latin, Gallia).
