Cerium Iodide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Iodide compounds are used in internal medicine. Treating an iodide with manganese dioxide and sulfuric acid sublimes the iodine.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.
Iodine is a Block P, Group 17, Period 5 element. The number of electrons in each of Iodine's shells is 2, 8, 18, 18, 7 and its electronic configuration is [Kr] 4d10 5s2 5p5. In its elemental form iodine's CAS number is 7553-56-2. The iodine atom has a radius of 133.1.pm and it's Van der Waals radius is 198.pm. Iodine in large amounts is poisonous but in small doses is only slightly toxic. Iodine forms compounds with many elements, but is less active than the other halogens, which displace it from iodides. Iodine exhibits some metallic-like properties. It dissolves readily in chloroform, carbon tetrachloride, or carbon disulfide to form purple solutions. It is only slightly soluble in water. Iodine compounds are important in organic chemistry and very useful in medicine. Potassium iodide finds use in photography. The deep blue color with starch solution is characteristic of the free element.Iodine is available in compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity).
