Description
Summary:In this work, the ceramics with the general formula of Pb 0.75 Ba 0.25 (Zr 0.65 Ti 0.35 ) 1-z Sn z O 3 (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°C/t calc = 3 h, and densification using free sintering method in conditions of: T s = 1250°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.
