摘要： 测定了NZP陶瓷中CZP、CM、CMS三种组成的导热系数随温度的变化，计算了三种组成的声子平均自由程，认为复杂的结构与组成是NZP陶瓷导热系数小的主要原因．

关键词: NZP陶瓷, 导热系数, 声子平均自由程

Abstract: The changes of the thermal conductivity of CZP 、CM and CMS composition in NZP familyceramics with temperature were studied. The phonon mean free path of CZP, CM and CMScomposition was calculated. It was found that complex structure and composition of NZP familyceramics are the main reason of resulting in their small thermal conductivity.

Key words: NZP family ceramics, thermal conductivity, phonon mean free path
