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 d(33) of the SPS textured material was nearly three times that of ordinary-fired (OF) materials and was stable up to 800° C (see Figure). These textured ceramics are promising candidates for high-temperature piezoelectric applications.
