2. Technical Capability

 

3. Product Description
Se, a chemical element from the group of chalcogens, exhibits various modifications. Gray metallic Se, the most stable form, showcases semi-metallic properties. Non-metallic red Se transitions to gray metallic Se above 80°C. Black Se, another modification, also converts to the gray metallic form above 80°C. Se boasts six naturally occurring isotopes, five of which are stable, underscoring its versatility.

Economically significant, Se is vital for all life forms and finds diverse applications. In medicine, Se-based preparations treat skin diseases, and 1% Se sulfide (SeS2) is a common ingredient in anti-dandruff shampoos. The glass industry utilizes Se to produce Se ruby glass for signal and traffic light systems. Se is also crucial in the semiconductor industry.

RongSin specializes in producing ultra high purity Se granules, ideal for analytical standards in health and safety research, as well as various commercial applications. Our granules, exhibiting the highest density and smallest average grain sizes, are perfect 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, available in sizes < 1 mm, 1-2 mm, and 3-5 mm, are amorphous and uniform. We produce materials using crystallization, solid-state, and otherultra high purification processeslike sublimation. Specializing in custom compositionsfor both commercial and research applications, we pioneer new proprietary technologies. Additionally, we cast rare earth metals and other advanced materials into various forms such as rod, bar, or plate, alongside other machined shapes, through processes likenanoparticlesand offer them in various forms.innovative solutionsandhigh-quality organometallics. Additionally, we produce Seasrods,pellets,powders,pieces,discs,ingots,wires, and in various compound forms, such asoxides. Custom shapes are also available upon request.
