[001]-textured Pb(Mg 1/3Nb 2/3)O 3-PbTiO 3 (PMN-PT) ceramics were synthesized by using templated grain growth method. Significantly high [001] texture degree corresponding to 0.98 Lotgering factor was achieved at 1 vol. BaTiO 3 template. Electromechanical properties for [001]-textured PMN-PT ceramics with 1 vol. BaTiO 3 were found to be d 33 1000 pC/N, d 31 371 pC/N, ε r 2591, and tanδ = ∼0.6. Elastoelectric composite based modeling results showed that higher volume fraction of template reduces the overall dielectric constant and thus has adverse effect on the piezoelectric response. Clamping effect was modeled by deriving the changes in free energy as a function of applied electric field and microstructural boundary condition.
