居里点(Curie point)又作居里温度(Curie temperature,Tc)或磁性转变点。是指磁性材料中自发磁化强度降到零时的温度,是铁磁性或亚铁磁性物质转变成顺磁性物质的临界点。低于居里点温度时该物质成为铁磁体,此时和材料有关的磁场很难改变。当温度高于居里点时,该物质成为顺磁体,磁体的磁场很容易随周围磁场的改变而改变。这时的磁敏感度约为10的负6次方。居里点由物质的化学成分和晶体结构决定。
...中都具有优良的性能.所以使用压电陶瓷时必须要 注意其使用的工作范围和使用的工作条件: (1)居里点(the Curie temperature):居里点也称居里温度,是在电场中.当 压电陶瓷加热到某一温度时.压电陶瓷才会显现其压电特性。

It is calculated by XRD analysis that the volume of crystal cell was decreased, and the c/a ratio was decreased resulted in the Curie temperature movement to lower temperature.
由XRD计算可知四方率(c/a比)减小,晶胞体积减小。 居里点随四方率(c/a比)减小,向低温移动。
