Abstract
Bismuth Sodium Titanate (BNT) has been investigated widely in terms of phase transitions, dielectric, piezoelectric and pyroelectric properties. The first transition temperature of this material is about 220°C. However, doped with Pb this material gives a higher dielectric constant and a lower phase transition temperature. The dielectric properties and structure of xPbTiO3-(1-x) Bi0.5Na0.5TiO3 solid solution are investigated. The phase boundary of this system is between 15-17%Pb. Pb also decreases the broadness of BNT dielectric response. Modifications with cations such as K+ and La3+ in 10%Pb doped BNT were studied in terms of dielectric properties and broadened phase transitions
