Grain orientation effects of Sr-Bi-Ti-Ta system, especially Sr x Bi 4 m x Ti 3 m x Ta x O 12 ( m = 3, x = 0-2) [SBTT3( x )] ceramics which belong to a bismuth layer-structured ferroelectric (BLSF) family, are studied using the hot-forging (HF) method on their piezoelectric properties. The grain orientation (HF) effects enhance the piezoelectric properties by a factor of two or more if compared with non-oriented ones. The electromechanical coupling factor, k 33 and the piezoelectric constant, d 33 of the grain oriented SBTT3(0.3) ceramics were relatively high values of 0.40 and 49.5 pC/N.
