Gallium is a chemical element; it has the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, [13] ...
Gallium trichloride is a common starting reagent for the formation of organogallium compounds, such as in carbogallation reactions. [15] Gallium trichloride reacts with lithium cyclopentadienide in diethyl ether to form the trigonal planar gallium cyclopentadienyl complex GaCp 3. Gallium(I) forms complexes with arene ligands such as ...
Chinese customs data show there have been no shipments of wrought and unwrought germanium or gallium to the U.S. this year through October, although it was the fourth and fifth-largest market for ...
China's abrupt announcement on Monday of controls from Aug. 1 on exports of some gallium and germanium products, also used in electric vehicles (EVs) and fibre optic cables, has sent companies ...
China is the biggest global source of gallium and germanium, which are produced in small amounts but are needed to make computer chips for mobile phones, cars and other products, as well as solar ...
Gallium arsenide (GaAs) is a III-V direct band gap semiconductor with a zinc blende crystal structure. Gallium arsenide is used in the manufacture of devices such as microwave frequency integrated circuits , monolithic microwave integrated circuits , infrared light-emitting diodes , laser diodes , solar cells and optical windows.
The dihalides are unstable in the presence of water disproportionating to gallium metal and gallium(III) entities. They are soluble in aromatic solvents, where arene complexes have been isolated and the arene is η 6 coordinated to the Ga + ion. With some ligands, L, e.g. dioxane, a neutral complex, Ga 2 X 2 L 2, with a gallium-gallium bond is ...
The spot price of gallium metal reached 1,975 yuan ($269.95) per kg on Oct. 18, up 18% since the start of July and up 8% since Aug. 1, d Chinese gallium prices hit 7-month high as demand improves ...
