合成了具有层状结构的热致相变材料四氯合锌酸十六铵( n-C16H33NH3)2ZnCl4,C16Zn)和四氯合锌酸十八铵( n-C18H37NH3)2ZnCl4,C18Zn)(在340～370 K的温度范围内存在着焓值较大的可逆固-固相变).并将此2种材料在乙醇溶液中结晶出一系列二元体系.对二元体系利用差热分析(DTA)和X射线衍射技术进行测定,构筑了C16Zn-C18Zn二元体系亚固相相图.根据相图,确定了w(C16Zn) =41.11％处有中间化合物( n-C16H33 NH3) (n-C18H37NH3) ZnCl4的存在,并测定在w(C16Zn)=16.19％和w(C16Zn) =63.07％2处存在着2个不变的共析点,2个共析点温度分别约为356和353 K.与同类体系的其它相图相比,在此相图的左右边界存在端际固溶体(α和β)和中间区域存在非化学计量相(γ).
