Vanadium Selenide is a crystal grown product generally immediately available in most volumes. Technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Vanadium is a Block D, Group 5, Period 4 element. The number of electrons in each of Vanadium's shells is 2, 8, 11, 2 and its electronic configuration is [Ar] 3d3 4s2. In its elemental form vanadium's CAS number is 7440-62-2. The vanadium atom has a radius of 131.1.pm and it's Van der Waals radius is 200.pm. Several vanadium compounds are toxic to some creatures despite the fact that it is an essential trace element. Vanadium is highly resistant to corrosion, so it is commonly used to alloy stainless steel grades. Vanadium compounds are used in advanced ceramics. Vanadium is a petrochemical cracking catalyst. Vanadium 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. Vanadium information, including Technical Data, Safety Data and its high purity properties , research , applications and other useful facts are discussed here . Scientific facts such as the atomic structure, ionization energy , abundance on Earth , conductivity and thermal properties are included. Vanadium was first discovered in Mexico City by Andres Manuel del Rio, a Spanish born and European educated Mexican mineralogist, in 1801. In honor of its beautiful multi-colored compounds, Vanadium was named after the word "Vanadis" meaning goddess of beauty in Scandinavian mythology. See Vanadium research below.
Selenium is a Block P, Group 16, Period 4 element. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its 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. The EPA does not classify selenium as carcinogenic, although selenium sulfide is a probable carcinogen. Selenates and selenites which are compounds of selenium, are highly toxic. Hydrogen selenide gas (SeH2) is the most acutely toxic compound of selenium. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. 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. Selenium was first discovered by Jons Berzelius in 1817. The origin of the name Selenium comes from the Greek word "Selênê" meaning moon. See selenium research below.
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
