Abstract

MgO addition Ba(Zr0.15Ti0.85)O3 (BZT) ceramics was prepared using conventional solid state reaction method and effect the MgO content in BZT ceramics on their sintering temperature, microscopic appearance, dielectric properties and ferroelectric properties was investigated. The result is that the addition of MgO can greatly reduce the sintering temperature of BZT ceramics. The average grain size can be gradually reduced as the concentration of MgO increases. The lattice constant is reduced by Mg2+ entering the crystal structure instead of Ti4+ or Zr4+. BZT ceramics exhibit excellent dielectric properties when a small amount of MgO was added. The maximum dielectric constant moves to the low temperature region when MgO content was increases. The hysteresis loop becomes thinner and the coercive field was significantly reduced.
