Description

压电陶瓷组成物
本发明涉及滤波器和电致伸缩元件用的一种电压陶瓷组成物。
Pb(Mg1/3 Nb2/3)03-PbZrO3-PbTiO3系压电陶瓷(PMN-PZ-PT)，由Pb(Mg1/3 Nb2/3)O3溶解在(Zr，Ti)O3中制取，机电耦合系数大，温度稳定性高，是具代表性的压电陶瓷，广泛用作滤波器和电致伸缩元件(日本专利，特公昭42-9716)。
然而，PMN-PZ-PT系压电陶瓷，其机械强度未必会令人满意，例如机械加工成压电元件时可能断裂或碎裂。
本发明目的在于提供一种压电陶瓷组成物，其机电耦合系数大，温度稳定性高，且改善了机械强度从而解决了上述问题。
为达到上述目的，本发明压电陶瓷是个三成分系压电陶瓷，由xPb(Mgw/3 Nb1-w/3)O3-yPb ZrO3-zPbTiO3组成，表示组成比的各点x、y、z(x+y+z＝1)基本上处在下列各点的连线上：A：(x＝0.70，y＝0.01，z＝0.29)，B：(x＝0.50，y＝0.01，z＝0.49)，C：(x＝0.05，y＝0.40，z＝0.55)，和D：(x＝0.05，y＝0.65，z＝0.30)，且处在图1的三成分组成图中为上述连线所包围的组成领域中，且w的值最好取大约0.8至1的范围。
换句话说，本发明的PMN-PZ-PT系压电陶瓷组成物的特点是，其MN/Pb比值基本上小于化学计量比1/2。
此外，本发明的压电陶瓷组成物还有这样的特点：基本上高达15％克分子比的Pb原子为选自Ca、Sr和Ba元素群的起码一种元素所取代。
Mb/Nb比减小到大约1/2的化学计算比值，这促使构成陶瓷的粒子的直径减小，而且提高陶瓷的机械强度。
此外，机械强度的提高并没有给机电耦合系数带来不利的影响。
图1的三成分组成图示出了本发明压电陶瓷(PMW-PZ-PT)组成物各成分的比例。
现在参看较佳的实施例具体说明本发明的优点如下。
量取压电陶瓷组成物预定量的各成分，例如PbO、TiO2、ZrO2、SrCO3、MgCO3和Nb2O3，往量取好的物料上加水，用球磨机将它们混合起来。
干燥得出的混合料，在大约700℃至900℃下焙烧两小时左右，使其不致完全烧结，再用球磨机湿磨，得出经调整的粉料。
往得出的经调整的粉料中加诸如水和聚乙烯醇之类的粘结剂，将混合料压实，再在大约1100℃至1300℃下焙烧约两小时，得出预定组成的压电陶瓷。
为进行三点弯曲试验和测定电气性能，将压电陶瓷加工，制备成试样。例如，将某些压电陶瓷制成30毫米×5毫米×0.3毫米的矩形试样，准备供三点弯曲强度试验用，再将其余的压电陶瓷制成直径10毫米厚一毫米的圆盘，磨光，通过烘焙在圆盘两面淀积一银电报之后，在大约80℃的绝缘油中，在绝缘油上加有2至3千伏/毫米场强的电场的情况下对圆盘进行极化处理，历时30分钟，制取电性能测定用的试样。
为对比起见，按制造实施例试样同样的方式法制取本发明范围之外的压电陶瓷组成物试样。
对实施例的上述试样和对比试样进行三点弯曲强度试验，并在半径方向上振动的情况下测定其机电耦合系数，结果如表1所示。
                                              表1

  *13   0.20   0.40   0.40   0.95   Sr   0.20     1100     28.3
表1中，符号x、z和w表示xPb(Mgw/3 Nb1-w/3)O3-yPbZrO3-zPbTiO3各成分的克分子比，符号A和a分别表示取代Pb的元素(即Sr、Ba或Ca)及其克分子百分比。
表中带星号的试样号表示本发明范围外的压电陶瓷(对比试样)。
从表1中可以看出，w值基本上等于或大于1的压电陶瓷(7号试样)，其三点弯曲强度低，w值基本上等于或小于0.8的压电陶瓷试样(8号试样)，其机电耦合系数Kp小。
若Pb原子为Ca、Sr和Ba所取代的百分比基本上超过15％(13号试样)，则机电耦合系数减小。
若PMN-PZ-PT的组成不在本发明的范围内(1，3，5，6和10号试样)，机电耦合系数Kp大幅度减小。
w取小于1的值，特别是当PMN的组成比x基本上小于0.05(6号和10号试样)时，机械强度提高得不能令人满意。
不言而喻，本发明并不局限于上述实施例，在不脱离本发明精神实质的前提下是可以就x、y、z和w的值以及Pb原子拟为Ca、Sr和/或Ba所取代的百分比进行种种修改的。
如上所述，本发明的压电陶瓷组成物，机电耦合系数Kp大，机械强度高，因而在机械加工过程中可以避免产生象断裂和碎裂之类的缺陷，从而可以使这种具有滤波器和电致伸缩元件所需要的优点的压电元件高产。
