| 英文摘要 | Calcium bismuth niobate CaBi2Nb2O9 (CBN) ceramic is a promising candidate for high-temperature piezoelectric applications due to its high Curie temperature. However, the extremely low piezoelectric properties hinder its application. A combination method with element doping and texturing was used to improve the electric properties of CBN ceramic. First of all, the Mn element was chosen to be doped to improve the piezoelectric and resistance properties of CBN ceramic. Then, an optimal composition was subsequently textured by templated grain growth (TGG) method to further improve the piezoelectric properties. The piezoelectric properties, Curie temperature (Tc), and resistivity of textured Ca0.95Mn0.05Bi2Nb2O9 ceramics (d (33) = 21, k (p) = 10.9 %, Tc = 942 A degrees C, rho = 2.1 x 10(5)Omega A center dot cm at 600 A degrees C) were improved obviously compared to pure random CBN ceramics (d (33) = 6, k (p) = 4.6 %, Tc = 930 A degrees C, rho = 0.6 x 10(5)Omega A center dot cm at 600 A degrees C). Furthermore, it has excellent resistance to thermal depoling and keep about 5.7 % kp until the temperature up to 600 A degrees C. This combination method makes the textured Ca0.95Mn0.05Bi2Nb2O9 ceramics to be a promising candidate for high-temperature piezoelectric applications. |
