Lead-free textured piezoceramics using tape casting: A review

In this review, the evolution of textured lead-free piezoceramics has been explored, primarily focusing on the technique of templated grain growth (TGG) and reactive-templated grain growth (RTGG), as an alternative to single crystals. The mechanics and properties of using template in guiding and orienting the ceramic grains into the same crystal orientation allow for piezoelectric properties approaching those of their single-crystal...
