Abstract A series of crystals of BaxSr1-x(NO3)2 (x = 0 - 0.98) were grown from aqueous solutions by the evaporation method and characterized by x-ray powder diffraction and high resolution x-ray diffraction. All diffraction data are well indexed according to simple cubic structure. The variation of lattice constants with the concentrations of Ba2+ in the crystals accorded quite well to the Vegard's Law. The results of high-resolution x-ray diffraction show that the crystalline quality of BaxSr1-x(NO3)2 decreases with x increasing. The distribution of Ba2+ between the solution and solid phase indicated that Ba2+ is enriched in the solid phase. It could be attributed to the solubility of Ba(NO3)2 in water being less than that of Sr(NO3)2.
