Samarium Metal Is A Silvery Yellow Lustrous That Tarnishes In Air Will Ignite At About 150 C - Chinaprice: contact company for price
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.
