In this paper, we have investigated the piezoelectric and ferroelectric properties of Ba(Zr0.04Ti0.96)O3 and CuO-Ba(Zr0.04Ti0.96)O3 ceramics prepared by the conventional solid solution method. Ba(Zr0.04Ti0.94)O3 ceramics were sintered at 1400, 1450, and 1500°C to optimize the sintering temperature of pure BZT. BZT ceramics with 1mol% of CuO added were sintered at 1300, 1350, 1400, 1450, and 1500°C...
In an effort for better understanding on (Bi0.5Na0.5)TiO3, donors such as Nb5+ and W6+ were doped by a conventional solid state mixing process. Their doping effects on ferroelectric and piezoelectric properties of (Bi0.5Na0.5)Ti1-xDxO3 were investigated. The solubility limit of Nb (xles0.01) and W (xles0.008) was determined by the X-ray diffraction after a typical sintering at 1150degC for 2 hours...
