Abstract :
The authors discuss the physical background of the possible diversity of modified lead-containing perovskite ceramic compositions with field-induced first order and diffused phase transitions, a number of particular model devices being considered. Specific changes of structure and properties of the PLZT (La-doped lead titanium zirconate) ceramics doped with 3D-elements and with radiation effects in some of the compositions are examined. In the applications considered the modified lead-containing perovskite compounds are used in the form of plates (thick films) about 0.3-mm thick cut from bulk ceramic bulbs
