Cesium Selenate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.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.
Cesium is a Block S, Group 1, Period 6 element. The number of electrons in each of Cesium's shells is 2, 8, 18, 18, 8, 1 and its electronic configuration is [Xe] 6s1. In its elemental form cesium's CAS number is 7440-46-2. The cesium atom has a radius of 265.5.pm and it's Van der Waals radius is 200.pm. Cesium compounds are slightly toxic. Cesium is a member of the alkali group of metals. It is one of three metals that occur as a liquid at room temperature - the others are mercury and gallium. Cesium 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. Cesium is used as an oxygen "getter" in vacuum and electronic tubes and as a component of photoelectric cells. Cesium compounds are considered to be slightly toxic. Atomic clocks use the microwave spectral line emitted by Cesium Isotope 133 for reference. Cesium chloride is an unproven treatment for cancer. Radioactive Cesium 137 is an artificial isotope produced that is an approved radiation source for cancer radiotherapy. Under pressure, Cesium hydride is stiffer than diamond. Laboratories use various cesium compounds for their ability to hydrogenate organic compounds. Cesium was first discovered by Fustov Kirchhoff in 1860.
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.
