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 ...
Galium babadaghense Yıld.; Galium baeticum (Rouy) Ehrend. & Krendl; Galium baghlanense Ehrend. & Schönb.-Tem. Galium baillonii Brandza; Galium baldense Spreng ...
Their proper names are gallium(III) fluoride, gallium(III) chloride, gallium(III) bromide and gallium(III) iodide. GaF 3 GaF 3 is a white solid which sublimes before it melts, with an estimated melting point above 1000 °C. [contradictory] It contains 6 co-ordinate gallium atoms with a three-dimensional network of GaF 6 octahedra sharing common ...
Gallium nitride (Ga N) is a binary III/V direct bandgap semiconductor commonly used in blue light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure .
China on Tuesday banned exports to the United States of the critical minerals gallium, germanium and antimony that have widespread military applications, escalating trade tensions the day after ...
Bauxite is the main source of the rare metal gallium. [17] During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin. [18]
The shorter-lived gallium-68 (half-life 68 minutes) is a positron-emitting isotope generated in very small quantities from germanium-68 in gallium-68 generators or in much greater quantities by proton bombardment of 68 Zn in low-energy medical cyclotrons, [4] [5] for use in a small minority of diagnostic PET scans.
