Cerium Sulfide 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.
Cerium is a Block F, Group 3, Period 6 element. The number of electrons in each of Cerium's shells is 2, 8, 18, 19, 9, 2 and its electronic configuration is [Xe]4f2 6s2. In its elemental form cerium's CAS number is 7440-45-1. The cerium atom has a radius of 182.5.pm and it's Van der Waals radius is 181.pm. Cerium is moderately toxic. Cerium is one of the products manufactured and distributed under the tradename AE Rare Earths. Cerium is the most abundant of the rare earths metals. It is characterized chemically by having two valence states , the +3 cerous and +4 ceric states. The ceric state is the only non-trivalent rare earth ion stable in aqueoussolutions.It is, therefore, strongly acidic and moderately toxic. It is also a strong oxidizer.The cerous state closely resembles the other trivalent rare earths. The numerous commercial applications for cerium include metallurgy, glass and glass polishing, ceramics, catalysts, as the electrolyte for solid oxide fuel cells when doped with yttrium, gadolinium or samarium and in phosphors. In steel manufacturing it is used to remove free oxygen and sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony. It is considered to be the most efficient glass polishing agent for precision optical polishing. It is also used to decolor glass by keeping iron in its ferrous state. The ability of cerium-doped glass to block out ultra violet light is utilized in the manufacturing of medical glassware and aerospace windows. It is also used to prevent polymers from darkening in sunlight and to suppress discoloration of television glass.
Cerium was first discovered by W. von Hisinger in 1903. The element was named after the asteroid Ceres. See Cerium research below.
Sulfur is a Block P, Group 16, Period 3 element. The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electronic configuration is [Ne]3s2 3p4. In its elemental form sulfur's CAS number is 7704-34-9. The sulfur atom has a radius of 100pm and it's Van der Waals radius is 180pm. Sulfur is a crucial element for all life and serves as both fuels and respiratory (oxygen-replacing) materials for simple organisms. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, Epsom salts, and barite. Sulfur, when organically bonded, is a component of all proteins, as the amino acids methionine and cysteine. In organic form, Sulfur is present in the vitamins thiamine and biotin. Sulfur is also a vital part of many enzymes and also in antioxidant molecules like glutathione and thioredoxin.Sulfur is available as compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity). Sulfur has been known since ancient times but was not accepted as an element until 1777. Antoine Lavoisier helped to convince the scientific commuity that sulfus is an element and not a compound.
