Abstract

The behavior of dielectric properties for the system Ba1-3x/2Laxx/2(Ti0.95 Zr0.05)O3 obtained by the conventional ceramic method was studied. The permittivity and dielectric losses were measured dynamically from 77 up to 500 K using the Thermoelectric Analysis (ATE), noticing that the fusion of the permittivity peaks reveals the possible existence of a phase mixture. Low lanthanum impurification percents can induce a relaxor behavior, a fact rarely approached by the literature on BZT ceramics. The resulting compounds (0.001 ≤x ≤0.010) exhibit marked decreases in the values of Curie temperature as well as increases of the dielectric constant.
