摘要：

CaBi2Nb2O9 ceramic is a promising candidate for high-temperature piezoelectric applications due to its high Curie temperature. However, extremely low piezoelectric properties hinder its application. A combination of Sm3+ donor doping and texturing was applied to address this problem. Piezoelectric coefficient, T-c, and resistivity of textured Ca0.95Sm0.05Bi2Nb2O9 ceramics (d(33)=23pC/N, T-c=941 degrees C, =4.1x10(5)cm at 600 degrees C) were obviously higher than those of pure random CaBi2Nb2O9 ceramics (d(33)=6, T-c=930 degrees C, =0.6x10(5)cm at 600 degrees C). Furthermore, it had excellent resistance to depolarization property, with k(p) of about 5.9% until 600 degrees C.
