| Abstract: | The thermotropic phase transitions in the perovskite type-layer compound and (n-C12H25NH3)2ZnCl4 were synthesized and a series of their mixtures were prepared from ethanol solutions. Nonisothermal kinetics of solid-solid phase transitions in C10Zn, C18Zn and their binary system was investigated by DSC. Kissinger and Ozawa methods were applied to determine the activation energy and reaction order of the solid-solid transitions. The results of two methods are in agreement. |
| Keywords: | dodecylammonium tetrachlorozincate decylammonium tetrachlorozincate solid-solid phase transition activation energy |
