3. Product description
Selenium (Se) is a versatile chemical element from the group of chalcogens. The gray metallic form of Se is the most stable, exhibiting semi-metallic properties. Red selenium, non-metallic in nature, transitions into gray metallic Se at temperatures above 80°C. A third form, black selenium, also converts to gray metallic above 80°C. Selenium has six naturally occurring isotopes, five of which are stable.

Selenium holds significant economic value and is vital for all forms of life. Medically, selenium-based preparations are utilized to treat skin ailments. In anti-dandruff shampoos, selenium sulfide (SeS2) is used at a concentration of 1%. In the glass industry, selenium is employed in the production of selenium ruby glass, integral to signal and traffic lights. Additionally, selenium is in high demand within the semiconductor industry.

RongSin excels in producing high purity selenium granules, essential for analytical standards in health and safety research, as well as 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, including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD),Metallic-Organicand Chemical Vapor Deposition (MOCVD). Our standard granules are amorphous and uniformly sized, ranging from < 1 mm, 1-2 mm, and 3-5 mm. We produce these materials through crystallization, solid state, and otherultra high purification processessuch as sublimation. American Elements is proficient in creatingcustom compositionsfor commercial and research applications and pioneering technologies. We also cast rare earth metals and most advanced materials into rods, bars, plates, and other machined shapes, utilizing processes such asnanoparticlesand various other forms.innovative solutionsandhigh-grade organometallics. We also produce Selenium (Se)in various forms such asrod,pellets,powder,pieces,disc,ingot,wire, and in compound forms, such asoxide. Other shapes are available by request.
