Abstract

Single crystals of BaTiO₃ were grown by templatcd grain growth (TGG). TGG involves contacting a single crystal "template" to a sintered polycrystalline matrix, then heating the assemblage to a temperature that promotes the migration of the single crystal boundary through the matrix. In this investigation the properties of millimetor-sized, plate-ahaped and bar-shaped, single crystals of BaTiOu grown by TGG were examined in order to compare the results to single crystals grown by conventional methods. A dielectric constant, , of 260, polarizations of PLI ∼ 16 μC/cm² and P_sat ∼ 21.5 μC/cm², electromechanical coupling coefficients of kaa ∼ 0.51 and fcni ∼ 0.1.8, and a piezoelectric coefficient of das ∼ 140 pC/N wore achieved. Kntrappccl porosity in the crystals made fully poling the crystals difficult.
