Scandium also interrupts melted aluminum crystalizing at a molecular level when the metal cools. Scandium is not particularly rare and can be found in small concentrations in the Earth’s crust. Specific Hazards Arising from the Material: Flammable in the form of dust when exposed to heat, sparks or flame. Specific Hazards Arising from the Material: Flammable in the form of dust when exposed to heat, sparks or flame. The maximum bond length is the M–N 2 (4) bond of scandium. Melting point: 2,804 degrees Fahrenheit (1,540 degrees Celsius) 7. Its low density and high melting point suggest applications as an alloying agent for lightweight metals for military and high-performance applications. Omissions? It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc2O3 oxide on the surface. When alloyed with aluminum and aluminum-based alloys, scandium limits high-temperature grain growth. Scandium is considered as flammable. May emit fumes of scandium oxide under fire conditions. The β-phase is body-centred cubic with an estimated a = 3.73 Å at 1,337 °C (2,439 °F). considered as flammable. Tris(methylcyclopentadienyl)scandium | C18H21Sc | CID 129688582 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. You may be familiar with the chemical symbols for hydrogen and oxygen, but can you match such lower-profile elements as gadolinium and erbium with their corresponding symbols? When did Elizabeth Berkley get a gap between her front teeth? Our editors will review what you’ve submitted and determine whether to revise the article. It is not known to be toxic. It is the 42nd most abundant element found in the Earths crust. Scandium is a chemical element, having the chemical symbol Sc.

May react with water under fire conditions to liberate flammable hydrogen gas. It develops a slightly yellowish or pinkish cast when exposed to air. Its atomic number (the number of protons) is 21 and its standard atomic weight is 44.9559 g•mol −1. Offer surplus and non-recyclable solutions to a licensed disposal company. Scandium is found in ores of tin, uranium and tungsten. Density: 1.734 ounces per cubic inch (3.0 grams per cubic cm) 5. Protective equipment: No special measures required. Fluoride compounds have diverse applications in current technologies and science, from oil refining and etching to synthetic organic chemistry and the manufacture of pharmaceuticals . ... Scandium has a low order of toxicity. Copyright © 2020 Multiply Media, LLC. However, it has very low density and higher melting point. Scandium tarnished in air and burn easily, once it has been ignited. Scandium is considered a flammable material. H228 (95.74%): Flammable solid [Danger Flammable solids] Information may vary between notifications depending on impurities, additives, and other factors. : Sc 3+ is enriched in Ca-Al-rich inclusions in meteorites relative to the composition of the solar system. Scandium Fluoride is a water insoluble Scandium source for use in oxygen-sensitive applications, such as metal production.
