摘要
The thermotropic phase transitions layer compound in the perovskite type （n-C）10)H)21)NH3)2ZnCl4 and （n-C）18)H)37)NH3)2ZnCl4 were synthesized and, at the same time, a series of mixtures C10Zn/C18Zn were prepared. The experimental binary phase diagram of C10Zn/C18Zn was established by means of differential scanning calorimetry （DSC） and X-ray diffraction. In the phase diagram, compound （n-C）10)H)21)NH3)（n-C）21)H)37)NH3)ZnCl4 and two eutectoid invariants were observed; two eutectoid temperatures are about 53 ℃ and 58 ℃. Contrasting with other similar systems, there are three noticeable solid solution ranges at the left and right boundary and middle of the phase diagram.
