ABSTRACT: High strain actuation can be obtained from crystallographically textured
piezoelectric ceramics. Single crystal piezoelectrics demonstrate high strain because crystal
orientation can be controlled the perfect lattice simplifies crystal orientation. Single crystals
actuate better than typical ceramics, but are expensive. Highly textured ceramics offer
an alternative path to easily aligned crystals. The crystallites in textured ceramics are
crystallographically oriented. Textured ceramics are expected to provide improved properties,
with lower processing costs. NexTech Materials is developing textured piezoelectrics
via Templated Grain Growth. In this process, anisotropic template particles are oriented in
a fine matrix. During heat treatment, the templates grow, resulting in a textured polycrystal.
Key Words: templated grain growth, piezoelectric, texture development, single crystal,
