Where is the good samarium oxide
Where is the good samarium oxide? For many people, the samarium oxides may be rarely heard, and here's the introduction to it:
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.
