3. Product Description
Se is a fascinating chemical element from the group of chalcohols. The most stable form, gray metallic Se, exhibits semi-metallic properties. Red Se, non-metallic, transitions to gray metallic Se above 80°C. Another variant, black Se, also converts to gray metallic at over 80°C. Se metal comprises six naturally occurring isotopes, five of which are stable.

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

RongSin excels in producing high purity Se granules, especially for analytical standards in health and safety research and various commercial applications. Our granules boast the highest possible density and the smallest average grain sizes, making them ideal for Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes like Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD),Metallic-Organicand Chemical Vapor Deposition (MOCVD). Our standard granules come in amorphous uniform pieces, available in sizes < 1 mm, 1-2 mm, and 3-5 mm. These materials are produced through crystallization, solid state methods, and otherultra high purification processessuch as sublimation. American Elements specializes in creatingcustom compositionsfor both commercial and research applications, as well as for innovative proprietary technologies. We also cast rare earth metals and other advanced materials into rod, bar, or plate forms, and other machined shapes using processes likenanoparticlesand even in the form ofOffering state-of-the-art solutionsandorganometallics. We also produce Seasrods,pellets,powder,pieces,discs,ingots,wire, and in compound forms, such asoxide. Other shapes are available by request.
