American Elements: Manganese Selenide Supplier & Tech Info

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 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 metal is a key component of aluminum alloys. 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.

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.
