Enhanced electrical properties of new lead-free 0.995Bi0.5(Na0.80K0.20)0.5TiO3-0.005LiNbO3 ceramics by (Ba0.98Nd0.02)TiO3 doping

Journal of Asian Ceramic Societies, 2021
It is well known that the Bi0.5(Na0.80K0.20)0.5TiO3 or BNKT ceramic possesses quite high piezoelectric coefficient (i.e., d33 ~ 151 pC/N). This research attempted to prepare (1-y)[0.995Bi0.5(Na0.80K0.20)0.5TiO3-0.005LiNbO3]-y(Ba0.98Nd0.02)TiO3 or (1-y)[0.
