white powder with light red color. The relative density was 7. 42. Melting point 2002 °c. Insoluble in water, soluble in acid. Can absorb carbon dioxide and water in the air.
extraction method: the rare earth chloride solution obtained by treating monazite or mixed rare earth ore is used as the raw material. Extraction with the P2 04-kerosene-HCl-ReCl3 system, first neodymium samarium grouping, raffinate to extract light rare earth, samarium and heavy rare earth extraction into the organic phase, and then use 2.0 mol/LHCI back extraction of heavy rare earth, the medium rare earth samarium gadolinium enrichment, after reduction by zinc powder, alkalinity method to extract europium, and then through oxalic acid precipitation, separation, drying, burning, europium oxide was prepared.
It is used as a red phosphor activator for color TV sets and as a phosphor for high-pressure mercury lamps.
