Selenium Metal is available as disc, granules, ingot, pellets, pieces, powder , rod, wire, and sputtering target. See research below. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms. Elements can also be introduced into alloys or other systems as fluorides, oxides or chlorides or as solutions. Selenium metal is generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.
