摘要：
The electric fatigue of (BaPb)TiO3 ferroelectric ceramics was studied in present experiments. The results show that the resistance of the ferroelectric ceramics increases with the fatigue cycles, and the resistivity change increases with the Curie temperature. The SEM observations reveal that microcracks occurred inside the ceramics; electrode ions were transported into the ceramics; segregation of the ceramic element took place and sometimes new phases occurred near the electrode during electric fatigue.
