RESEARCH ON ANTIFERROELECTRIC MATERIALS

Abstract

Research was conducted on antiferroelectric materials to develop a capacitor material superior to existing ceramic and film materials in energy storage per unit volume. Experiments are described on ceramic compositions that have fieldenforced antiferroelectric to ferroelectric transformations resulting in double hysteresis loops with a linear central region. Several examples are shown of compositions that have this type of loop over a wide temperature range. Experiments with very low PbSnO3 contents improved the morphotropy of the phase boundary but the resulting compositions showed large threshold field at and below room temperature. Work will continue to employ compositional variation to try to improve further the character and temperature dependence of the hysteresis loops. (Author)
