Gadolinium(Ⅲ) oxide - Preparation Method
Open Data Verified Data
extraction method: the rare earth chloride solution obtained by processing monazite or mixed rare earth ore is extracted with Pz 04-kerosene-HCI-RCl3 system, first Nd-samarium grouping is carried out, and the raffinate is used to further extract light rare earth, samarium and heavy rare earth were extracted into the organic phase and then used 2. The heavy rare earth was back-extracted with Omol/L HC1 to obtain the medium rare earth samarium gadolinium enrichment, which was reduced by zinc powder. After The europium was extracted by alkalinity method, the mixed rare earth grouping method was used to dissolve the samarium mixed rare earth, gadolinium oxide was prepared by oxalic acid precipitation, separation, drying and burning.
