Samarium Oxide Introduction

Sm2O3 to slightly yellowish white powder, body-centered cubic or monoclinic two kinds of crystal. Similar chemical properties of rare earth oxide, samarium oxide is no exception, but has its moments and other oxides different, as 1.45M · B. Density 8.347g / cm3. Melting point 2262 ℃. Insoluble in water, soluble in acid. Absorb carbon dioxide and water in the air. It can be used to absorb infrared light-emitting glass additive, the photosensitive material in the paint, and made SmCo permanent magnetic materials and the production of metal samarium. By the processing monazite or mixed rare earth ore from the rare earth chloride solution by extraction, stripping, zinc reduction, plus oxalic acid precipitation, separation, burning derived.
