Abstract

The dielectric and piezoelectric properties of the ceramic system, BST–xBCTZ (x = 0, 0.05, 0.1, 0.2), were investigated. The primary nanopowders were synthesized using citrate–nitrate combustion route to obtain the homogenous compounds. The results show that the addition of BCTZ has a great effect on the microstructure and electrical properties of ceramics. The dielectric and piezoelectric properties are improved with the addition of BCTZ. Transition temperature T c increases with increasing BCTZ content, which is mainly contributed to the increase in the Ba/Sr ratio. The optimal dielectric properties and piezoelectric properties for the BST–xBCTZ ceramics have been obtained at x = 0.05.
