摘要:
采用溶胶- 凝胶制备工艺制备了( Na015 Bi015 ) 0.935 Ba01065 ( Ti 1- x H fx ) O3 ( x= 0.002、0.005、0.01、0.02) 无铅压电陶 瓷。研究了陶瓷的铁电、压电性能和显微结构。结果表明, 随着铪掺杂量的增加, 陶瓷晶相转变为4 方相, 电滞回线发生畸 变。对电滞回线的拟合分析表明, 有两种铁电畴存在, 随温度的升高, 电滞回线呈现部分类似于反铁电的特征。该陶瓷体系在 x= 0.005 时, 其压电应变常数, 径向机电耦合系数, 厚度耦合系数, 介电常数, 介电损耗分别为210 pC/ N, 0.252, 0.446, 1 293, 0.055。
Abstract:
Lead- f ree ( Na01 5 Bi01 5 ) 01 935 Ba01 065 ( T i1- x Hfx ) O3 ( x = 0.002, 0.005, 0.01, 0.02) ceramics w ere fabricated via a sol- gel method. T he fer roelect ric, piezoelect ric proper ties and micro st ructure of the ceramics w ere invest igated. It w as found that incr easing Hf do pants w ould result in a tetr ag onal crystalline phase and the hysteresis loop w as distor ted. T he simulat ion of the loop at dif ferent temperature hint s that tw o species of domains may be ex isted. Analog ous ant i- fer roelect ric char acter part ially appeared in the loop as the temperature increased.
