Thallium 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.
Thallium is a Block P, Group 13, Period 6 element. The number of electrons in each of Thallium's shells is 2, 8, 18, 32, 18, 3 and its electronic configuration is [Xe] 4f14 5d10 6s2 6p1. In its elemental form thallium's CAS number is 7440-28-0. The thallium atom has a radius of 170.pm and it's Van der Waals radius is 196.pm. Thallium and its compounds are highly toxic. Thallium is primarily used for its electrical conductivity as thallium sulfide which changes with exposure to infrared light. This ability makes the compound useful in photocells. Thallium bromide-iodide crystals have been used as infrared optical materials. Thallium has been used, with sulfur or selenium and arsenic, to produce low melting glasses which
becomes fluid between 125 and 150 C. These glasses have properties at room temperatures similar to ordinary glasses and are said to be durable and
insoluble in water. Thallium oxide has been used to produce glasses with a high index of refraction, and is also used in the manufacture of photo cells.
Thallium 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. Thallium was first discovered by Sir William Crookes in 1861.
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.
