摘要:
采用传统固相法制备了(Na0.5Bi0.5)0.6(Bi1-ySry)0.4TiO3压电陶瓷(记为NBBST-y),利用复阻抗谱分析了电性能,探究了陶瓷中微观组成与电性能的关联。对于NBBST-y压电陶瓷,其晶粒电阻具有典型负温度系数的电阻-温度特性,根据Arrhenius Law拟合计算得到激活能0.574 eV <Ea<0.980 eV,表现为电子导电特征。
Abstract:
(Na0.5Bi0.5)0.6(Bi1-ySry)0.4TiO3(NBBST-y for short)piezoelectric ceramics were prepared by a traditional solid-state synthesis method, the electrical properties were analyzed through complex impedance spectroscopy, and the relationship between microscopic composition and electrical properties was investigated. For NBBST-y piezoelectric ceramics, resistance characteristic for grain shows a typical negative temperature coefficient of the resistance-temperature characteristics. The activation energy(0.574 eV<Ea <0.980 eV)for NBBST-y piezoelectric ceramics calculated according to the Arrhenius Law, it has the characteristic of electron conduction.
