Samarium Metal
Samarium is a silvery-yellow lustrous metal that tarnishes in air. Samarium will ignite in air at about 150 °C. The metal is relatively hard and brittle. It has a rhombohedra structure, a density of 7.536 gm/cm3, a melting point of 1072 °C, and a boiling point of 1900 °C.Samarium oxide, or samaria, occurs as a sesquioxide with the formula Sm2O3. The trivalent oxide is a light-yellowish powder with a specific gravity of 7.1gm/cm3 and a formula weight of 348.70. The bivalent oxide is red-brown.Samarium has 16 isotopes. Natural occurring samarium contains 7 isotopes, with 3 being unstable with long half-lives. The major commercial application of samarium is in samarium-cobalt magnets which have permanent magnetization second only to neodymium magnets; however,samarium compounds can withstand significantly higher temperatures, above 700°C, without losing their magnetic properties. Radioactive isotope samarium-153 is the major component of the drug samarium (153Sm) lexidronam (Quadramet)which kills cancer cells in the treatment of lung cancer, prostate cancer,breast cancer and osteosarcoma. Purity: Sm/TREM ≥ 99.99% Packing: In iron drums with inner double PVC bags of 100kg net each, or packed according to customers' specifications.
