About

American Elements specializes in producing high purity uniform shaped Selenium Slugs with the highest possible density High Purity Slugsand smallest possible average grain sizes for use in semiconductor, 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-Organic and Chemical Vapor Deposition (MOCVD). Our standard Slug sizes range from 1/8" x 1/8" to 1/4" x 1/4" and 3 mm diameter. We can also provide Slugs outside this range for ultra high purity thin film applications, such as fuel cells and solar energy layers. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes nanoparticles. See research below. We also produce Selenium as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.

The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electron configuration is [Ar] 3d10 4s2 4p4. The selenium atom has a radius of 120 pm and a Van der Waals radius of 190 pm. Selenium is a non-metal with several allotropes: a black, vitreous form with an irregular crystal structure three red-colored forms with monoclinic crystal structures and a gray form with a hexagonal crystal structure, the most stable and dense form of the element. One of the mose common uses for selenium is in glass production the red tint that it lends to glass neutralizes green or yellow tints from impurities in the glass materials. Selenium was discovered and first isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. The origin of the name Selenium comes from the Greek word "Selênê," meaning moon.

Free Test Sample Program

We recognize many of our customers are purchasing small quantities directly online as trial samples in anticipation of placing a larger future order or multiple orders as a raw material for production. Since our primary business is the production of industrial quantities and/or highly consistent batches which can be used for commercial production and purchased repeatedly in smaller quantity, American Elements offers trial samples at no charge on the following basis. Within 6 months of purchasing materials directly online from us, you have the option to refer back to that order and advise that it is the intention of your company, institution or lab to either purchase a larger quantity, purchase the material in regular intervals or purchase more on some other basis.

We will then evaluate your future needs and assuming the quantity or number of future purchases qualify, we will fully credit your purchase price with the next order. Because of the many variables in the quantity and number of orders you may place, it is impossible to evaluate whether your future order(s) will qualify for this program prior to your placing your next order. Please know American Elements strongly desires to make this free sample program available to you and will make every effort to do so once your next order is placed.
