USES :
Samariumcarbonate (2:3) hydrateis a water insoluble Samarium source that can easily be converted to other Samarium compounds, such as the oxide by heating (calcination).Carbonate compoundsalso give off carbon dioxide when treated with dilute acids. Samarium is used in laser applications and for its dielectric properties and in filter glass on Nd:YAG solid state lasers. It forms stable titanate compounds with useful dielectric properties. Samarium Carbonate is generally immediately available in most volumes.Ultra high purity and high puritycompositions improve both optical quality and usefulness as scientific standards.Nanoscale(See alsoNanotechnologyInformation andQuantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered.Titan produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade,USPandEP/BP(European Pharmacopoeia/British Pharmacopoeia)and follows applicableASTMtesting standards.Typical and custompackagingis available. Additional technical,researchand safety (MSDS) information is available as is aReference Calculatorfor converting relevant units of measurement.
