摘要: The piezoelectric properties of Nd and V cosubstituted bismuth titanate ceramics, (Bi4-y,Ndy)1-(x/12)(Ti3-x,Vx)O12 [BNTV-y (x=0.01, y=0.00~1.00)] , are investigated. Furthermore, the grain orientation effects BNTV-y ceramics on their studied by hot forging (HF) method. electromechanical coupling factor, k33, ordinarily fired (OF) BNTV-y0.75 ceramic was 0.21, which is one highest k33 values for layer-structured ferroelectrics (BLSFs). On other hand, oriented BNTV-y0.25 0.30.
