How to making Sm2O3

Sm2O3 is a slightly yellowish white powder, body centred cubic or monoclinic. The chemical properties of rare earth oxides are similar, and samarium oxide is no exception, but its magnetic moments are different from other oxides, 1.45 M · B. The density of 8.347 g/cm3. Melting point is 2262 ℃. Insoluble in water, soluble in acid. It absorbs carbon dioxide and water in the air. It can absorb infrared ray glass additives, coating in photosensitive materials, and make samarium drill permanent magnet material and make metal samarium. The extraction of chlorinated rare earth solution obtained from the treatment of solitary stone or mixed rare earth minerals is obtained by extraction, anti-extraction, zinc powder reduction, and oxalic acid precipitation, separation and burning.
