Abstract
Chemically induced interface migration (CIIM) in Pb[(Co 1/3Nb2/3)0.1Zr0.6Ti 0.3]O3 (PCNZT) ceramics was investigated while controlling the PbO content. After sintering, stoichiometric samples were heat-treated in a PbO atmosphere allowing diffusion of PbO into grain boundaries (alloying), while the samples with excess PbO were heat-treated in air in order to promote PbO evaporation (dealloying). In both cases, an interface moving against their curvature was observed. Because of the zigzag structure of the grain boundaries, the mechanical properties improved.
