研究了Ｎａ０．５Ｂｉ０．５ＴｉＯ３和（Ｎａ０．５Ｂｉ０．５）０．９４Ｂａ０．０６ＴｉＯ３陶瓷的电滞回线、压电性能和热滞现象·得到（Ｎａ０．５Ｂｉ０．５）０．９４ Ｂａ０．０６ＴｉＯ３陶瓷的剩余极化Ｐｒ＝１９ｕＣ／ｃｍ２、矫顽场Ｅｃ＝４．７ｋＶ／ｍｍ．发现用适量的Ｂａ２＋取代（Ｎａ０．５Ｂｉ０．５）２＋尽管压电性能有所提高，但同时使得材料的温度稳定性大大降低．
D-E hysteresis, piezoelectric properties and temperature hysteresis phenomena of (Na0.5Bi0.5)TiO3 and (Na0.5Bi0.5)0.94Ba0.06TiO3 ceramics were investigated. Remnant polariza- tion (Pr=19uC/cm2) and coercive field (Ec =4.7kV/mm) of (Na0.5Bi0.5)0.94Ba0.06TiO3 ceramic were obtained in the experiment. Although the substitution of Ba2+ for (Na0.5Bi0.5)2+ can im- prove the piezoelectric properties, it can also induce the deterioration of temperature stability.
