摘要：

The (001) textured (Ba0.85Ca0.15)(Zr0.1Ti0.9)O-3 (BCZT) thick films were fabricated via screen printing using anisotropically shaped BaTiO3 templates on platinum substrate. The dielectric, ferroelectric, and piezoelectric properties of the random and textured BCZT thick films have been investigated. The orientation degree (Lotgering's factor) of 81% calculated from X-ray diffraction patterns was obtained. The Curie temperature of the textured BCZT thick film shifted to a high temperature in comparison with the random BCZT thick film. The textured BCZT thick film exhibited excellent electric properties with the piezoelectric constant d(33)* = 427 pm/V and remnant polarization P-r=15.8 mu C/cm(2) sintered at 1300 degrees C for 4 h with 81% of Lotgering's factor.
