Abstract

The effect of aging on Sr2+ modified Lead Zirconate Titanate (PSZT) ceramics have been studied. Aging was assessed by the measurement of dielectric constant and dielectric loss tangent as a function of time and temperature. Dielectric constant and dielectric loss tangent measured at different temperature range. Absolute rate of aging and relative rate of aging was determined. The PSZT ceramic showed sharp dielectric peak at temperature 300oC. The result showed that with increased temperature both the dielectric constant and rate of aging increased.
