Abstract :
The effects of reactor radiation [1015–1018 neutrons/cm2 (per square centimeter)] on the dielectric properties of BaTiO3, 96% BaTiO3 +4% PbTiO3, 95% BaTiO3 +5% CaTiO3, and lead zirco-titanate were studied. Complex permittivity and large-signal hysteresis properties were measured before and after irradiation, after room temperature aging, and after 500 C (degrees centigrade) heat treatment. Effects on the hysteresis properties and the small-signal permittivity were small except for exposures of 1018 neutrons/cm.2 All of the measured properties were affected in some degree by aging and heat treatment.
