9.Solubility: insoluble in water , soluble in inorganic acid
Applications:
1.Materials for making metal samarium, magnetic materials and memory elements;
2.It can be used as a glass additive for infrared absorption and a coating in photosensitive materials. Production of samarium cobalt permanent magnet materials and raw materials for the production of metal samarium;
3.Used in the manufacture of samarium metal, samarium cobalt permanent magnet materials, electronic devices and ceramic capacitors, samarium cobalt alloys with high coercivity and high magnetic energy product;
Specifications:
Preparation:
The extraction method treats the rare earth chloride solution obtained from monazite or mixed rare earth ore, and extracts, firstly carries out neodymium and samarium grouping, extracts samarium and heavy rare earth into the organic phase, then strips medium and heavy rare earth, and then strips heavy rare earth. The rare earth samarium-gadolinium enrichment obtained by grouping is reduced to extract europium, and the mixed rare earth grouping method is used to separate samarium and gadolinium. Samarium oxide is obtained by dissolving, precipitating, separating, drying and burning.
