Abstract
Fiber textured 0.68PMN-0.32PT was fabricated using the Templated Grain Growth (TGG) process. Isostructural template materials (BaTiO3, SrTiO3) were [001] oriented in a fine matrix during tape casting. A high degree of [001] texture (Lotgering factor > 0.8) was obtained by heteroepitaxial growth of oriented single crystal PMN-PT on the template particles. The effect of matrix chemistry, time, and temperature on the texture evolution was investigated for both a reactive matrix and a perovskite powder matrix. [001] textured PMN-PT has a piezoelectric coefficient of 1300 pC/N up to 10 kV/cm and 0.32% strain at 50 kV/cm.
