【Abstract】 The equilibrium solubility of NaCl-ZnCl₂-HCl（～9%）-H₂O quaternary system at 25℃was determined and the phase diagram was constructed.This system is complicated with one compound 5NaCl·ZnCl₂·0.5H₂O which has been obtained from the system and has been characterized by XRD.The result shows that compound 5NaCl·ZnCl₂·0.5H₂O is the new one which has not been reported before.For compound 5NaCl·ZnCl₂·0.5H₂O parameter of unit cell is a =14.900nm;c=25.160 and it belongs to quadratic system.更多还原
