Asked by Wiki User. Gallium can form a number of compounds. [2] Gallium first became recognized as a critical mineral resource during World War II and was used in the core of the first atomic bomb to help stabilize the plutonium crystal structure of a gallium-plutonium alloy developed as part of the Manhattan Project. Isotopes: There are 27 known isotopes of gallium ranging from Ga-60 to Ga-86. 22 Adorable and Funny Animal Pets … Gallium when painted on to glass forms a brilliant mirror. The Concise Oxford Dictionary of English Etymology. A Dictionary of Nursing. In fact, about 95 percent of all gallium produced is used to make gallium arsenide (GaAs), a compound used in microwave and infrared circuits, semiconductors and blue and violet LEDs, according to Chemistry Explained. In May 2018, the U.S. Department of the Interior, in coordination with other executive branch agencies, published a list of 35 critical minerals (83 FR 23295), including gallium. Gallium does not conduct electricity well, and is known as a semiconductor.That means gallium can be used in computers to make them work. Retrieved October 18, 2020 from Chief among them in economic importance are: Gallium(III) arsenide (GaAs), Gallium(III) hydroxide (Ga(OH)3), Gallium(III) nitride (GaN), and Gallium(III) phosphide (GaP). Gallium's boiling point is more than eight times higher than its melting point on the absolute scale — the greatest ratio between melting point and boiling point of any element. With a boiling point of 2477 K (2204 C or 3999 F), gallium has one of the largest liquid ranges of any element. Then if you set it back down, it would solidify again. Actinium is the third elemen…, Indium (revised) Etched gallium arsenide wafer. Sources: Gallium may be found as a trace element in sphalerite, diaspore, bauxite, coal, and germanite. Gallium was discovered spectroscopically in 1875 by the French chemist Paul-Émile Lecoq de Boisbaudran. In 2018, Integrated Circuits accounted for 68% of U.S. gallium consumption, optoelectronic devices accounted for 30%, and research and development accounted for 2%. . Zinc, which has an atomic number of 30, sits next to gallium on the periodic table. When painted on glass, gallium turns into a lustrous mirror. For webinar sponsorship information, visit or email n. the chemical element of atomic number 31, a soft, silvery-white metal that melts at about 30°C, just above room temperature. Here are some interesting facts about gallium. Copyright ©2020. Gallium is a bright blue-silver metal with a melting point low enough you can melt a chunk in your hand. Note: This article, originally published in 1998, was updated in 2006 for the eBook edition. We continue to review some of the most important materials in heat treatment and metallurgy. To one of these gaps, at atomic number 31, Mendeleev assigned the element the provisional name of ekaaluminum. Note: This article, originally published in 1998, was updated in 2006 for the eBook edition.
