Effect of Neutron Irradiation on the Ferroelectric Properties of Barium Titanate Ceramics

Abstract

The changes in ferroelectric properties of barium titanate ceramics caused by irradiation with reactor neutrons were investigated. The temperature dependence of the dielectric permittivity and the temperature hysteresis of barium titanate ceramics nonirradiated and irradiated with an integrated neutron flux from 10/sup 14/ to 10/sup 19/ n/cm/sup 2/ were measured. Moreover, the changes in the dielectric hysteresis loop of barium titanate ceramics caused by neutron irradiation were investigated. (auth)
