  • The solid-solid phase transitions in the perovskite type layer materials (n-C12H25NH3)2ZnCl4 (C12Zn) and (n-C18H37NH3)2ZnCl4 (C18Zn) that are one kind of potential thermal storage material, were synthesized and, at the same time, a series of their mixtures C12Zn/C18Zn were prepared. The experimental binary phase diagram of C12Zn/C18Zn was established by means of differential scanning calorimetry (DSC) and X-ray diffraction. In the phase diagram a stable solid compound (n-C12H25NH3)(n-C18H37NH3)ZnCl4 (C12C18Zn) and two eutectoid invariants were observed. It is noticeable that the phase diagram contains solid solution ranges.
