Detailed Product Description: | Features: CAS: 12060-58-1 MF: O3Sm2 MW: 348.72 EINECS number: 235-043-6 Melting point 2325 ° C Density 8.35 g / mL at 25 ° C (lit.) refractive index 1.97 form nanopowder Merck 14, 8347 CAS Database 12060-58-1 (CAS DataBase Reference) EPA Substance Registry Samarium oxide (Sm2O3) (12060-58-1) parameter index: Name an average particle size of purity bulk density than the surface area of ??the color price (including tax) Nano samarium oxide 40nm 99% 80m2 / g 0.20g/cm3 white 1500 yuan / kg main purposes: Chemical properties of white slightly yellowish powder. Insoluble in water, soluble in acid. Samarium metal used for manufacturing purposes, magnetic memory devices and materials available for use infrared absorption glass additives, photosensitive material coating, made samarium cobalt permanent magnet materials, as well as raw material for the production of metal samarium. Use mainly for the production of metallic samarium, samarium cobalt permanent magnet materials, electronic devices and ceramic capacitors. Extraction processing production methods or mixed rare earth ore monazite rare earth chloride solution obtained with P2O4-kerosene-HCl-RCl, Extraction System, the first grouping for neodymium samarium, samarium and heavy rare earth extraction human organic phase, then 2. 0mo1 / L HCl for stripping the heavy rare earth, and then 5.0 mol / L HCl stripping of heavy rare earths. The resulting group of rare earth samarium gadolinium enrichment by zinc reduction, alkalinity extraction of europium, the use of mixed rare earth separation of samarium and gadolinium grouping method. After dissolution, with oxalic acid precipitation, separation, drying, burning, samarium oxide was obtained. Its Sm2 (C2Od) 3 → Sm2O3 +3 CO2 +3 CO |
