Zinc Selenide is a crystalline solid used as a semiconductor and in photo optic applications. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement. Zinc is a Block D, Group 12, Period 4 element. The electronic configuration is [Ar] 3d10 4s2. In its elemental form zinc's CAS number is 7440-66-6. The zinc atom has a radius of 133.5.pm and it's Van der Waals radius is 139.pm. Zinc is a bluish-white, lustrous metal. It is brittle at ordinary temperatures but malleable at 100 to 150 o C. It is a fair conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide. It has unusual electrical, thermal, optical, and solid-state properties that have not been fully investigated. The metal is employed to form numerous alloys with other metals. Brass, nickel, silver, commercial bronze, soft solder, and aluminum solder are some of the more important alloys. Selenium is a Block P, Group 16, Period 4 element. The electronic configuration is [Ar] 3d10 4s2 4p4. In its elemental form selenium's CAS number is 7782-49-2. The selenium atom has a radius of 116.pm and it's Van der Waals radius is 190.pm. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. These properties make selenium useful in the production of photocells and exposure meters for photographic use, as well as solar cells. Below its melting point, selenium is a p-type semiconductor and has many uses in electronic and solid-state applications. Selenium is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. American Elements semi conducting materials are crystal structures produced from ultra high purity starting materials synthesized by our high purity production facility which includes several large electric muffle furnaces, a tube furnace for hydrogen reduction, 50 gallon glass-lined Pfaudler reactors supported by our analytical laboratory containing X-ray diffraction, SEM, AA, BET surface area, and ICP Spectrometry for trace metals analysis.
