    • Abstract

       

      Textured (K$_{0.44}$Na$_{0.52}$Li$_{0.04}$) (Nb$_{0.86}$Ta$_{0.10}$Sb$_{0.04}$)O$_3$ thick film was fabricated by the screen printing method with plate-like NaNbO3 particles as template. Thick film with 75% grain orientation was prepared. Remnant polarization and coercive field observed from the P–E loops of textured thick film were 3.6 $\mu$C cm$^{−2}$ and 21 kV cm$^{−1}$, respectively. Textured (K$_{0.44}$Na$_{0.52}$Li$_{0.04}$) (Nb$_{0.86}$Ta$_{0.10}$Sb$_{0.04}$)O$_{3}$ thick film exhibited diffusion behaviour by analysing the temperature dependence of permittivity and loss tangent. The result of leakage current density showed a conduction mechanism of Schottky emission. Piezoelectric (PZT) properties of the thick film were characterized by the relationship of unipolar strain and applied electric field and the PZT constant $d^∗_{33}$ of textured thick film reached to 150 pm V$^{−1}$. Nonlinear PZT property of the thick film was investigated by Rayleigh law.
