Samarium 154 Oxide (Samarium-154) is a stable (non-radioactive) isotope of Samarium. See below table for ENSDF Citation and Half Life. It is both naturally occurring and produced by fission. Samarium 154 Oxide is one of over 250 stable isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications. Samarium Oxide is also available in ultra high purity and as nanoparticles. For thin film applications it is available as rod, pellets, pieces, granules and sputtering targets and as either an ingot or powder. Samarium Oxide 154 isotopic material is generally immediately available.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.
Samarium is a Block F, Group 3, Period 6 element. The number of electrons in each of Samarium's shells is 2, 8, 18, 24, 8, 2 and its electronic configuration is [Xe]4f6 6s2. In its elemental form samarium's CAS number is 7440-19-9. The samarium atom has a radius of 180.4.pm and it's Van der Waals radius is unknown. Samarium is somewhat toxic. Samarium is primarily utilized in the production of samarium-cobalt (Sm2Co17) permanent magnets. Samarium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is also used in laser applications and for its dielectric properties. Samarium-cobalt magnets replaced the more expensive platinum-cobalt magnets in the early 1970s. While now overshadowed by the less expensive neodymium-iron-boron magnet, they are still valued for their ability to function at high temperatures. They are utilized in lightweight electronic equipment where size or space is a limiting factor and where functionality at high temperature is a concern. Applications include electronic watches, aeospace equipment, microwave technology and servomotors. Because of its weak spectral absorption band samarium is used in the filter glass on Nd:YAG solid state lasers to surround the laser rod to improve efficiency by absorbing stray emissions. Samarium was first discovered by Paul Emile Lecoq de Boisbaudran in 1879. Samarium is named after the mineral samarskite. See Samarium research below.
