Samarium Sulfate Solutions are moderate to highly concentrated liquid solutions of Samarium Sulfate. They are an excellent source of Samarium Sulfate for applications requiring solubabilzed materials. American Elements can prepare dissolved homogenous solutions at customer specified concentrations or to the maximum stoichiometric concentration. Packaging is available in 55 gallon drums, smaller units and larger liquid totes. American Elements maintains solution production facilities in the United States, Northern Europe (Liverpool, UK), Southern Europe (Milan, Italy), Australia and China to allow for lower freight costs and quicker delivery to our customers. .American Elements metal and rare earth compound solutions have numerous applications, but are commonly used in petrochemical cracking and automotive catalysts, water treatment, plating, textiles, research and in optic, laser, crystal and glass applications. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered. We also produce Samarium Sulfate Powder. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and deposited utilizing sputtering targets and evaporation materials for uses such as solar energy materials and fuel cells.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.
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. See Sulfur research below.
