Abstract

Fiber textured Sr_0.53Ba_0.47Nb₂O₆ ceramics were reactively sintered to ≥95% of the theoretical density from a mixture of SrNb₂O₆ and BaNb₂O₆ powders. Texture in <001> was obtained by templated grain growth on <001>-oriented acicular KSr₂Nb₅O₁₅ template particles. The most highly textured ceramics had a peak dielectric constant of 23, 600 (at T_c = 128°C), a remanent polarization (P_r) of 20.3 μC/cm², a saturation polarization (P_sat) of 24 μC/cm² (69-96% of single crystal), and a piezoelectric charge coefficient (d₃₃) of 84 pC/N (76-93% of single crystal). A model, correlating polarization with grain orientation, predicts that P_r increases sharply when a percolating grain network forms to transfer charge between elongated grains.
