Jan 1, 2013 · The aging degradation of the piezoelectric properties of lead zirconate titanate (PZT) was investigated at different heat treatment temperatures (30 to 80% of Curie temperature (TC)).

Feb 1, 2015 · Experiments on aging and fatigue of bulk ferroelectrics are thoroughly reviewed. Lead-based PZT and lead-free BNT–BT and KNN materials are covered. Various fatigue regimes and factors are classified. Defect associate formation and alignment are analyzed by density functional theory.

Screen printed lead zirconate titanate (PZT) layers offer possibilities for both sensing and actuation applications. PZT materials are known to suffer a long-term ageing process that can affect their performance as functional materials.

Jul 8, 2009 · PZT-SKN showed low-field aging rates that were intermediate between hard and soft material. This aging was affected by potassium and oxygen vacancy concentration. High-field aging of PZT-SKN showed it to act like a soft material.

Sep 1, 2017 · This paper aims to study the effects of heat treatment temperatures on the aging degradation of piezoelectric properties, i.e. piezoelectric coefficient (d 33) and planar electromechanical coupling factor (k p), in soft and hard PZT ceramics. Aging degradations of d 33 and k p of the samples were measured for 192 h prior to heat treatments. The ...

Dec 7, 2013 · The aging degradation was more pronounced when the heat treatment temperature was greater than 50% of T C. These results can be applied to predict the aging rate of electronic devices containing a PZT component.

Jul 17, 2021 · In our study, hard PZT-based piezoelectric ceramics of the 0–1.5 mol.% (Ca, Fe) co-doped PSZT were selected to investigate the domain structure, dielectric loss, and aging effects under AC electric fields.

Sep 1, 2014 · In this work, lead zirconate titanate (PZT) was mixed with normal Portland cement at 30–50% by volume to produce 0–3 connectivity composites and the effect of age up to 1 year on the piezoelectric coefficient (d 33) of PZT–cement composite after poling was investigated.

Electrical aging in lead zirconate titanate (PbZr x Ti 1−x O 3) thin films has been intensively studied from a macroscopic perspective. However, structural origins and consequences of such degradation are less documented.

Many studies have been performed on aging of lead zirconate titanate (PZT), but a single model has not been universally accepted. An aim of this research was to determine whether harmonic analysis could distinguish among the models for the aging of PZTs.
