STEM-X-EDS analysis of morphotropic PZT ceramics

A TEM-EDS analysis technique is applied to estimate dopant incorporation and Zr/Zr+Ti fluctuation in morphotropic PZT ceramics starting from powders synthesized by two routes. A solid-state synthesis route leads to less reactive powders requiring severe conditions to reach full densification. The hydrothermal route leads to more reactive powders that can be fully densified at lower temperature. In addition, the influence of Ni addition was analyzed.
