Abstract
Lead zirconate titanate (PZT) ferroelectric materials were prepared by the traditional solid phase reaction method, and the passive capacitors of parallel slab were processed. At last the total dose radiation effect on the PZT ferroelectric material capacitors with the ELV-8 electron linear accelerator were tested. The ferroelectric performance parameters of capacitors before and after radiation were tested and compared. The results show that the encircling area of polarization-field hysteresis loop is gradually decreased, and that the parameters such as the saturation polarization, the remnant polarization and the coercive field exhibit a linear decrease with the increase of irradiation dose of high energy electron. When the irradiation dose is 1 × 108 rad (Si), the attenuation ranges of those parameters are respectively 14.1%, 15.0% and 2.7%. It is obvious that the anti-total dose radiation capability of the sample plates can reach 1 × 108 rad (Si).
