Abstract
研究了Bi（0.5）Na（0.5）TiO3（BNT）掺杂对BaTiO3（BT）-Nb2O5-ZnO三元系统介电性能与微结构的影响.BaTiO3陶瓷在低温端（-55℃）的电容量变化率随BNT含量的增大而单调降低,而高温端（150℃）的变化率持续增大,且居里温度单调递增.掺杂1.0wt%与2.5wt%BNT的BT陶瓷满足EIA X8R特性.SEM观察表明,BaTiO3陶瓷内部由细小的基质晶粒和第二相晶粒组成,且第二相比例随BNT含量的增加而增大.XRD分析表明,基质晶粒为BaTiO3,第二相晶粒为CaB2Si2O8和NaBiTi6O（14）.条状第二相CaB2Si2O8和NaBiTi6O（14）的产生改变了BT系统的内应力结构是钛酸钡陶瓷居里温度升高以及电容量温度特性改善的原因.
