Abstract

A lead-free high-Curie-point Aurivillius-phase ferroelectric ceramic, CaBi2Nb2O9, has been fabricated by spark plasma sintering (SPS). It has a Curie point (943 °C) that is much higher than previously reported (650 °C). The piezoelectric constant d33 of the SPS textured material was nearly three times that of ordinary-fired (OF) materials and was stable up to 800 °C. These textured ceramics are promising candidates for high- temperature piezoelectric applications.
