Single-phase bismuth tungstate (Bi2WO6) ceramics with high relative density (> 99%) were fabricated by spark plasma sintering. Ferroelectric, dielectric, and piezoelectric properties of Bi2WO6 ceramics were investigated. Almost saturated polarization-electric field (P-E) hysteresis loops with a remanent polarization (P-r) of similar to 16.1 mu C/cm2 and a coercive field (E-c) of similar to 3.7 kV/mm were obtained. Curie point and second phase transition temperatures were observed at 937 degrees +/- 5 degrees and 665 degrees +/- 5 degrees C, respectively. The average piezoelectric constant (d(33)) of this high Curie point ceramic is 15 +/- 0.2 pCN-1.
