Abstract: Three pseudo-side-binary systems, LiCl-(2ZnCl2•KCl); LiCl-(ZnCl2•2KCl) and (2ZnCl2•KCl)-(ZnCl2•2KCl) in the pseudo-ternary LiCl-(2ZnCl2•KCl)-(ZnCl2•2KCl), have been investigated by visual-polythermal, DTA and XRD methods. Three new compounds were found in these systems. The ternary compound Li3K2Zn4Cl13 congruently melts at 245 ℃. The incongruent ternary compound Li12K2ZnCl16 and the binary incongruent compound K5Zn4Cl13 peritecticly melt at 432 ℃ and 249 ℃ respectively.
