Tin(II) Selenideis a crystalline solid used as a semiconductor and in photo optic applications.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Tin is a Block P, Group 14, Period 5 element. The number of electrons in each of Tin's shells is 2, 8, 18, 18, 4 and its electronic configuration is [Kr] 4d10 5s2 5p2. In its elemental form tin's CAS number is 7440-31-5. The tin atom has a radius of 140.5.pm and it's Van der Waals radius is 217.pm. Organometallic compounds of tin are very toxic and tin salts are also considered to be toxic. Tin as single atoms or molecules are not toxic. Tin compounds sprayed onto glass are used to produce electrically conductive coatings. These have been used for panel lighting and for frost-free windshields. Most window glass is now made by floating molten glass on molten tin (float glass) to produce a flat surface. Crystalline tin-niobium alloy is superconductive at very low temperatures. This promises to be important in the construction of superconductive magnets that generate enormous field strengths but use practically no power. Tin is the basis for many eutectic alloys and the discovery by early man that copper could be better formed and crafted if tin were added producing the first bronze and launching what we refer to as the "Bronze Age" and the first Neolithic metal tools, cooking utensils, and jewelry produced from rudimentary bronze. An important tin compound is the chloride, which is used as a reducing agent and as a mordant in calico printing. Tin is also used in various metal alloys (See AE Alloys). Tin was first discovered by Early Man.The origin of the word tin comes from the Latin word Stannum which translates to the Anglo-Saxon word tin.

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.
