Manganese Selenide (MnSe) 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.
Manganese is a Block D, Group 7, Period 4 element. The number of electrons in each of Manganese's shells is 2, 8, 13, 2 and its electronic configuration is [Ar] 3d5 4s2. In its elemental form manganese's CAS number is 7439-96-5. The manganese atom has a radius of 136.7.pm and it's Van der Waals radius is 200.pm. Manganese in excess is toxic, in particular the inhalation of manganese in powder or dust form. Manganese metal is a key component of aluminumalloys. Manganese oxide is used in dry cell batteries. Manganese is used in steel production to remove sulfur and oxygen. Manganese is the colorant in natural amethyst stones and is used in glass and ceramics to also create the amethyst color. It is used like the element cerium to "decolorize" glass by offsetting the green from impurities of ferric ions. Permanganate is a powerful oxidizing agent and is used in medicine. It is added as a nutritional supplement for both human and animal consumption. Recently, the oxide in the form of various perovskite structures have demonstrated applications in oxygen generation and solid oxide fuel cells. Manganese was first discovered by Johann Gahn in 1774. The name Manganese originates from the Latin word mangnes meaning magnet. See Manganese 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:
