METHOD FOR SYNTHESIS OF MONOPHASE BARIUM FLUORIDE NANOPOWDER DOPED WITH FLUORIDE OF RARE-EARTH METAL

摘要

FIELD: chemistry.;SUBSTANCE: invention can be used in photonics an inorganic synthesis as a catalytically active phase. A fluorinating compound is mixed with a solution containing barium salt and a salt of a rare-earth element to obtain a precipitate which is washed and dried. The solution mixed with the fluorinating compound contains barium ions and ions of a rare-earth element in molar ratio between 0.74:0.26 and 030:0.70, respectively.;EFFECT: invention enables to obtain phase-clean crystalline nanopowder with high concentration of rare-earth elements.;6 cl, 12 ex
