Study on piezoelectric, dielectric and dispersive phase transition of BaTiO_3-BaZrO_3-CaTiO_3 ceramics

摘要

The dielectric, piezoelectric properties and dispersive ferroelectric phase transitions of (0.84 - x) BaTiO3-0.16CaTiO(3)-xBaZrO(3) ternary ceramics were investigated in this manuscript. The study found that the optimum BaZrO3 doping amount was 0.1 mol%. Compared to the binary system, the ternary system has a denser microstructure and a more uniform grain size, and more excellent electrical properties. The influence mechanism of BaZrO3 doping on the system was explained in detail by lattice theory and domain theory.
