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.

5. Application:
The main uses of Se are:
1). Quality
RongSin is dedicated to supplying only the highest quality products. Selection of the best quality raw materials combined with stringent manufacturing controls assures you of reliable products. We maintain a sharp focus throughout every level of the organization to ensure that every facet of our customer's needs are fulfilled. Our commitment to the highest possible quality control and lot-to-lot consistency is unparalleled.
2). Variety/Flexibility
RongSin offers a diverse range of standard formulations, shapes, and sizes. Moreover, we adjust compositions, forms, and quantities as necessary to meet your requirements. We listen to our customers and leverage over 20 years of accumulated expertise to provide innovative, cost-efficient solutions for your most challenging metallurgical needs.
3). Custom Powder Metal for Research & Development
Many powder metal suppliers lack the capability to produce small order quantities for R&D purposes. With our unique test furnaces, RongSin New Materials is perfectly positioned to supply companies and institutions who are testing the properties and feasibility of various alloy families. Furthermore, once the desired specification is met, we are also capable of scaling up the production of the alloys to meet your production needs.
4). At The Lowest Cost
We strive to certify to the highest possible U.S. standards while supplying materials at the lowest possible world price.
