Lithium is a Block S, Group 1, Period 2 element. The electronic configuration is [He] 2s1. In its elemental form lithium's CAS number is 7439-93-2. The lithium atom has a radius of 152.pm and it's Van der Waals radius is 182.pm. Lithium is a member of the alkali group of metals. It has the highest specific heat of any material and the highest electrochemical potential. This makes it important in applications involving heat transfer and as the anode in batteries. Lithium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Lithium is a dopant in advanced optical glass. It is used as an alloy in light weight metals.
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.
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. See a discussion of American Elements Ultra High Purity and Analytical capabilities. See Crystal Growth for processes used to fabricate semiconductor materials, which include:
-
Crystal "pulling" by the Czochaiski method for production of semiconductor materials
-
Flux growth and gradient freeze
-
Directional solidification of fluorites using both the Bridgman-Stockbarger and float zoning techniques
