Samarium oxide is an inorganic metal compound with a molecular formula of Sm2O3, which can be used to prepare other organic materials and catalysts. It is a white, slightly yellowish powder, insoluble in water but soluble in acid.
Samarium oxide production method
The rare earth chloride solution obtained from monazite or mixed rare earth ore is extracted by extraction method, and extracted with the P2O4-kerosene-HCl-RCl system. HCl is used for back extraction of heavy rare earths. After the heavy rare earth samarium-gadolinium enrichment obtained by grouping is reduced by zinc powder, europium is extracted by alkalinity method, the mixed rare earth grouping method is used to separate samarium and gadolinium. After dissolution, precipitation with oxalic acid, separation, drying, and burning, samarium oxide is prepared.

Samarium oxide Sm2O3 powder overview
Samarium oxide (chemical formula is Sm2O3) is a pale yellowish white powder, in a body-centered cubic or monoclinic system. Rare earth oxides have similar chemical properties, and samarium oxide is no exception, but its magnetic moment is 1.45M·B, which is different from other oxides. The density is 8.347 g/cm3. The melting point is 2262°C. Samarium oxide is insoluble in water but soluble in acid. Samarium oxide absorbs carbon dioxide and water in the air. Under humid conditions or in dry air above 150°C, samarium oxide is easily formed on the surface of samarium metal. Similar to metallic iron, the oxide layer is peeled from the metal surface, exposing more metal to continue the reaction. It can be used as an additive for luminescent glass that absorbs infrared light, as a coating for photosensitive materials, as well as for manufacturing samarium permanent magnet materials and metal samarium. Monazite or mixed rare earth chloride solution ore is obtained by refining, steam stripping, zinc powder reduction, oxalic acid precipitation, separation, and combustion.
Samarium oxide sm2O3 powder application
Samarium oxide can be used as an additive for infrared light-emitting glass, photosensitive material coating, samarium permanent magnet material and metal samarium production.
Samarium oxide is used in optical and infrared absorbing glass to absorb infrared radiation.
Samarium oxide is used as a neutron absorber in the control rods of nuclear power reactors.
Samarium oxide can catalyze the dehydration and dehydrogenation of primary and secondary alcohols
Prepare other salt.
