Physicochemical Property of Gadolinium oxide powder

White amorphous powder. Relative density 7.407, melting point (2330±20)℃. Insoluble in water, soluble in acid. Easily absorb moisture and carbon dioxide in the air.Gadolinium oxide CAS 12064-62-9 When interacting with ammonia, gadolinium hydrate is precipitated.

Production methodprocess of Gadolinium oxide powder

The rare earth chloride solution obtained from monazite or mixed rare earth ores was extracted by P2O4-kerosene-HC1-R system, firstly Nd-Samarium grouping, and the extraction residue was used to further extract the light rare earths, and the samarium and heavy rare earths were extracted into the organic phase, and then the medium and heavy rare earths were back-extracted by 2.0mol/LHCl to obtain the medium rare earth samarium and gadolinium enriched material, and then the europium was extracted by the alkalinity method by the reduction of zinc powder. After the extraction of europium by alkalinity method, the mixed rare earths of samarium gadolinium were dissolved by the method of rare earth grouping, and the Gadolinium oxide Raw Materials were obtained by precipitation with oxalic acid, separation, drying and burning.
