Tailoring particle alignment and grain orientation during tape casting and templated grain growth

Journal of the American Ceramic Society, 2018
Abstract The quality of crystallographic alignment in textured ceramics produced by tape casting and templated grain growth (TGG) has been little studied despite its demonstrated impact on magnetic, piezoelectric, and optical properties.

Development of a Templated Grain Growth System for Texturing Piezoelectric Ceramics [PDF]

Adaptive Structures and Material Systems, 2001
Abstract High strain actuation can be obtained by engineering the crystallographic texture of piezoelectric ceramics. Single crystal piezoelectrics have significantly improved strain performance because crystal orientation can be controlled during use — their highly perfect lattice greatly simplifies the crystal orientation.
