Overview of SM2O3
SM2O3 is a slightly yellowish white powder, intimately cubic or monopolite. The chemical nature of rare earth oxides is similar, and oxidation is no exception, but its magnetic moment is different from other oxides, which is 1.45 m · b. The density is 8.347 g / cm3. Melting point 2262 ° C. Insoluble in water, soluble in acid. Absorb carbon dioxide and water in the air. It can be used as a luminescent glass additive, and the coating in the photosensitive material, as well as the preparation of the diamond permanent magnet material and the production of metal. The chlorinated rare earth solution obtained by treating a residential stone or mixed rare earth mine is reduced by extraction, anti-extract, zinc powder, gave sedimentation, separation, and burning.
