Abstract:

Fatigue studies showed that a material degrades due to change in temperature. Thermal shocking is one of the most severe phenomenon in degradation of piezoelectric ceramics. A lead zirconate titanate thin piezoelectric ceramics disc has been experimentally analyzed to observe its thermal shocking effects. Disc was shocked from 100oC from a thermal chamber environment to deionized water at 200C. Dielectric constant and coupling factors at frequency of maximum and minimum impedance have been measured for thirty five shocks. A noticeable change in values has been observed by using reliable instrumentations and appropriate equations. The study will be useful in modeling, development and the reliability of sensitive piezoelectric instruments facing such conditions.
