Templated grain growth of high coercive field CuO‐doped textured PYN‐PMN‐PT ceramics
Abstract
This paper explores the templated grain growth and texturing of Pb(Yb1/2Nb1/2)O3‐Pb(Mg1/3Nb2/3)O3‐PbTiO3 (PYN‐PMN‐PT) ceramics. A PbO‐CuO liquid phase was determined to substantially increase the growth of PYN‐PMN‐PT on barium titanate template particles. Texturing resulted in an 83% enhancement in strain behavior (754 pm/V) compared with random PYN‐PMN‐PT ceramics (413 pm/V). The increased Pb(Yb1/2Nb1/2)O3 (PYN) content of textured 21PYN‐41PMN‐38PT resulted in a high coercive field of 13.9 kV/cm. Residual barium titanate templates reduced the polarization from 33.7 to 26.2 µC/cm2 and slightly decreased the Curie temperature (236‐224°C). These results show that textured PYN‐PMN‐PT is a promising material for high strain and coercive field transducers.
