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.

5. Application:
The primary uses of Se include:
1). Quality
RongSin is dedicated to supplying only the highest quality products. By selecting the best raw materials and implementing stringent manufacturing controls, we ensure that our products are reliable. We focus intensively at every level of our organization to fully meet our customers' needs. Our commitment to the highest quality control and lot-to-lot consistency is unparalleled.
2). Variety/Flexibility
RongSin offers a broad range of standard formulations, shapes, and sizes. Furthermore, we are flexible in adjusting compositions, forms, and quantities to meet your specific requirements. We listen to our customers and leverage over 20 years of expertise to provide innovative, cost-effective solutions for your toughest metallurgical challenges.
3). Custom Powder Metal for Research & Development
Many powder metal suppliers lack the capability to produce small quantities for R&D purposes. Our unique test furnaces enable RongSin New Materials to supply these needs to companies and institutions testing the properties and feasibility of various alloy families. Once a desired specification is achieved, we can scale up production to meet your larger volume demands.
4). At The Lowest Cost
We strive to certify our materials to the highest possible U.S. standards while supplying them at the lowest possible global price.
