Abstract

Presentation describes the ferroelectric domain structure of Lanthanum-modified lead titanate ceramics, as deduced by transmission electron microscopy, including the ferroelectric to paraelectric phase transformation. A significant result was the observation of a minimum grain size for ferroelectric (twin) formation.
