The (h00) textured Ba(Zr0.085Ti0.915)O3 (BZT) ceramics were fabricated by templated grain growth using anisotropically shaped BaTiO3 (BT) templates. A high orientation degree (Lotgering's factor) of 85% calculated from X-ray diffraction (XRD) patterns was obtained. The dielectric, ferroelectric, piezoelectric properties of the random and textured BZT ceramics have been studied. The Curie temperature of the textured BZT ceramics was 94 °C, which was higher than that of the random BZT ceramics. The textured BZT ceramics exhibited excellent piezoelectric performance with the piezoelectric coefficient d_{33} = 234 pC/N, strain levels of 0.22% at 40 kV/cm, normalized strain (S_{\text{max}}/E_{\text{max}}) level of 550 pm/V calculated from the unipolar strain--electric field (S--E) hysteresis loops and remnant polarization P_{\text{r}} = 11.46 μC/cm2 sintered at 1450 °C for 4 h with 85% of Lotgering's factor.
