3. Product description
Se, a chemical element from the chalcohol group, exhibits various modifications. Gray metallic Se, the most stable form, possesses semi-metallic properties. Red Se, non-metallic, transitions to gray above 80°C. Another form, black Se, also converts to gray at similar temperatures. Se metal has six naturally occurring isotopes, five of which are stable.

Se holds significant economic value and is vital for all life forms. Medically, Se-based preparations treat skin diseases and Se sulfide (1% in shampoos) combats dandruff. In the glass industry, Se is used to produce Se ruby glass for signal and traffic lights. The semiconductor industry also demands Se extensively.

RongSin excels in providing high purity Se granules for analytical standards in health and safety research, among other commercial applications. These granules boast the highest density and smallest average grain sizes, making them perfect for Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes, including Thermal, Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, and Atomic Layer Deposition (ALD).Metallic-Organicand Chemical Vapor Deposition (MOCVD). Our granules, available in sizes < 1 mm, 1-2 mm, and 3-5 mm, are produced using crystallization, solid state, and otherultra high purification processeslike sublimation. American Elements is adept at producingcustom compositionsfor commercial and research purposes and pioneering new technologies. We also cast rare earth metals and other advanced materials into rods, bars, or plates, and offer custom machined shapes through processes such asnanoparticlesand in the form ofcutting-edge solutionsandhigh-quality organometallics. We also produce Seasrods,,pellets,,powder,,pieces,,discs,,ingots,,wires, and in compound forms, such as, and in compound forms, such asoxide. Other shapes are available by request.. Other shapes are available by request.
