Abstract

Ceramics corresponding to the lead titanate zirconate (PZT) ceramic system modified with strontium in different regions of phase diagram (Zr/Ti = 20/80, 40/60, 53/47, 60/40), were sinterized at 1290 ºC for 70 minutes, the optimal sintering regimen according to previous studies. Tetragonal and rombohedral phases were obtained (mixed rombohedral and tetragonal were obtained for Zr/Ti = 53/47). As the Zr/Ti ratio increases, tetragonality and Curie temperature decreases, while the grain size did not show a noticeable variation. Our samples showed normal ferroelectric/paraelectric transitions and a Curie-Weiss behaviour above transition temperature.
