Scandium Selenide (ScSe) 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.
Scandium is a Block D, Group 3, Period 4 element. The number of electrons in each of Scandium's shells is 2, 8, 9, 2 and its electronic configuration is [Ar] 3d1 4s2. In its elemental form scandium's CAS number is 7440-20-2. The scandium atom has a radius of 160.6.pm and it's Van der Waals radius is 200.pm. Scandium is mildly toxic. Scandium is a metal that has many of the characteristics of the rare earth elements, particularly yttrium. It is a light material with a higher melting point than aluminum giving uses in aerospace and most recently, in racing bicycles and golf clubs. Doping zirconium oxide with scandium oxide produces a low temperature electrolyte in solid oxide fuel cells. Scandium information, including Technical Data, Safety Data and its high purityproperties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Scandium was first discovered by Lars Nilson in 1879. The origin of the name, Scandium, comes from the Latin word 'Scandia' meaning Scandinavia. See Scandium 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.
