Dielectric Properties of Pb0.75Ba0.25(Zr0.65Ti0.35)(1-z)SnzO3 Ceramics

In this work, the ceramics with the general formula of Pb0.75Ba0.25(Zr0.65Ti0.35)(1-z)SnzO3 (PBZST) for a constant x = 0.25, constant y = 0.35 and variable z = 0, 0.02, 0.04, 0.06, 0.08, 0.10 were obtained and examined. Powders synthesis was carried out using calcination method in conditions of: T-calc = 850 degrees C/t(calc) = 3 h, and densification using free sintering method in conditions of: T-s = 1250 degrees C/t(s) = 4h. For the obtained samples of PBZT and PBZTS ceramics, the microstructure and basic dielectric properties in the frequency function tests were performed. The PBZTS ceramics with relaxor properties is an interesting material to use in the modern electrical engineering, for instance as electrostriction transducers, sensors, or pulse capacitors.
