Abstract

Ba_1-xAl_xTi_1-ySi_yO_3-xN_x(BA_xTS₄N) piezoceramics were prepared by solid-state reaction sintering. The effects of AlN and SiO₂ co-doping on the phase structure and electrical properties of BaTiO₃ ceramics were investigated and analyzed. The ceramics adopt a tetragonal crystal symmetry accompanied by the appearance of secondary phases Ba₂TiSi₂O₈ and Ba₄Ti₂O₂₇. The results of temperature dependence of dielectric constant indicate that the Curie temperature of BA_xTS₄N ceramics is independent of doping content. The BA_xTS₄N ceramic for the composition of x = 3% obtains the optimum ferroelectric properties with the remnant polarization (2_Pr) of 14.69 C/cm² and the maximum piezoelectric coefficient (d₃₃) of 230 pC/N.
