Осаждение фосфатов редкоземельных элементов из расплавов на основе эквимольной смеси LiCl–KCl

Abstract

Formation of rare earth phosphates was studied in the melts based on LiCl–KCl eutectic mixture at 550 оC and various initial phosphate to rare earth mole ratios. The effect of melt stirring on the rate and completeness of the reaction was investigated. For the analysis of the phase composition a full-profile Rietveld analysis of the X-ray diffraction patterns of the precipitates obtained was applied, and the phases were identified using the PDF-2 powder diffraction file database.
