Crystallographic texturing of ferroelectric ceramics is an established method of inducing single crystal-like properties in a ceramic material via epitaxial grain growth according to the template used, otherwise known as Templated Grain Growth (TGG). The piezoelectric enhancement is dependent on the degree of TGG throughout the ceramic, which is closely linked to the tape casting parameters and sintering conditions. Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) perovskite ferroelectrics with morphotropic pha...

Relaxor-PbTiO3-based ternary ferroelectric solid-solution ceramics with high Curie temperature end members are effective to achieve broader usage temperature range and drive field stability, meanwhile with comparable piezoelectric responses to binary Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT). Templated grain growth is viable alternative to crystal growth that uses templates to induce crystal orientation along a specific direction, thus enhancing the piezoelectric response. In this research, perovskite Pb...
