Gallium Uses, Properties, & Facts Britannica
Elemental gallium is a soft, silvery metal at standard temperature and pressure. In its liquid state, it becomes silvery white. If enough force is applied, solid gallium may fracture conchoidally. Since its discovery in 1875, gallium has widely been used to make alloys with low melting points. See more Gallium is a chemical element with the symbol Ga and atomic number 31. Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, gallium is in group 13 of the periodic table and is similar to the … See more Gallium is found primarily in the +3 oxidation state. The +1 oxidation state is also found in some compounds, although it is less common … See more In 1871, the existence of gallium was first predicted by Russian chemist Dmitri Mendeleev, who named it "eka-aluminium" from its position in his periodic table. He also predicted several properties of eka-aluminium that correspond closely to the real properties of … See more 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). … See more Elemental gallium is not found in nature, but it is easily obtained by smelting. Very pure gallium is a silvery blue metal that fractures conchoidally like glass. Gallium liquid expands by 3.10% when it solidifies; therefore, it should not be stored in glass or metal containers … See more Gallium does not exist as a free element in the Earth's crust, and the few high-content minerals, such as gallite (CuGaS2), are too rare to serve as a primary source. The abundance See more Semiconductor applications dominate the commercial demand for gallium, accounting for 98% of the total. The next major application is … See more WebDec 19, 2024 · Gallium is one of four non-radioactive metals that are liquid at or near room temperature.

WebGallium readily alloys with most metals. It is particularly used in low-melting alloys. It has a high boiling point, which makes it ideal for recording temperatures that would vaporise a thermometer. Biological role Gallium has no known biological role. … WebGallium, you see, melts at 30 o C, which means that on a hot day, you hold it in your pocket at your peril. Surprisingly however it's not very volatile. In fact Gallium has the largest … WebLithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure. The chemical symbol for Lithium is Li.. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element.
