Poling PZT Ceramics | International
Therefore the apparent stability of the PZT material seems to increase with increasing time. For example, after poling, a property such as dielectric constant (K) may age -3% in the first day, -3% over the following ten days, -3% over the following 100 days, etc. Aging rates are not consistent from PZT material to material, with hard PZT ...

Processing and piezoelectric properties of porous PZT ceramics
Porous PZT piezoelectric ceramics have been manufactured by using different pore formers (PMMA, dextrin) and sintered at 1200 °C over a range of porosity (5–45%). The porosity increased with an increase in the content of pore formers and the increased porosity led to a decrease in the Young's modulus. For the PMMA and dextrin …
