Abstract: Phase chemical relation of quaternary system CsBr-DyBr3-HBr(13%)-H2O at 25℃ for CsBr and DyBr3 reaction in HBr was studied for the first time,a new kind of compound 5CsBr·3DyBr3·24H2O was found in the system.X-ray powder diffraction, thermal analysis(TG and DTA) and polarization-character of new compound obtained from the system were investigated.Meanwhile,the synthetic mechanism of compound Cs3DY2Br9 was suggested here on the basis of phase chemical relation of the system.
