Nickel Selenite 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.
Nickel is a Block D, Group 4, Period 4 element. The number of electrons in each of Nickel's shells is 2, 8, 16, 2 and its electronic configuration is [Ar]3d8 4s2. In its elemental form nickel's CAS number is 7440-02-0. Nickel is sometimes found free in nature but is more commonly found in ores. The nickel atom has a radius of 149.pm and it's Van der Waals radius is 163.pm. Nickel and its compounds are considered to be carcinogenic. Nickel carbonyl is a very toxic gas. It is extensively alloyed with iron, chromium, molybdenum, tungsten and other metals produce stainless and other anti-corrosive steel and other corrosion-resistant alloys. It is highly electronically conductive and has many applications as a result. It is the basis of the nickel hydride battery. Most recently, its conductive properties have made it an ideal component for ceramic anode formulations used in oxygen generation and solid oxide fuel cell applications. Catalytic nickel is used to hydrogenate vegetable oils. Nickel additions to glass and ceramic glazes impart a bright green. It is also used in pigments for this purpose. Nickel information, including Technical Data, Safety Data and its high purityproperties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Nickel was first discovered by Alex Constedt in 1751.
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.
