About Selenium Ring

 Selenium RingSelenium Rings can be customized in width, thickness, and ring diameter. Selenium rings may have a custom shape hole and may be open or closed. American Elements specializes in producing high purity uniform shaped Selenium rings. American Elements offers custom rings with annealed or hard tempers and will meet most of the common Milspec or ASTM standards. Selenium rings are hollow, circular pieces of metal and can be produced in custom sizes. In addition to standard alloys, American Elements also specializes in corrosion resistant alloys, high temperature applications, and custom shapes and forms including custom inside and outside dimensions and threading. American Elements also produces Selenium as rod, ingot, powder, pieces, disc, granules, wire, and in compound forms, such as oxide. Selenium rings can be used as components in several applications.

Selenium Bohr ModelSee more Selenium products. Selenium (atomic symbol: Se, atomic number: 34) is a Block P, Group 16, Period 4 element with an atomic radius of 78.96. 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. Elemental SeleniumOne of the most 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.
