【Abstract】 The influence of formula on the dielectric properties of Ba (Ti, Zr)O 3(BTZ) series capacitor ceramics has been investigated by means of orthogonal design experiments. The major、secondary influencing factors and the influencing tendency of various factors’ levels for the dielectric properties of BTZ ceramics have been obtained. The order of major and secondary influencing factors is Nb 2O 5、BaZrO 3/BaTiO 3、ZnO、CeO 2 for permittivity values( ε ),and Nb 2O 5、 BaZrO 3/BaTiO 3、 ZnO、CeO 2 for dielectric losses (tan δ ). At the same time, the optimum formulae for ε and for tan δ have been obtained in the experimental conditions. The BTZ ceramics having optimum comprehensive properties has been obtained by means of orthogonal design experiments, which have high ε (≥13200),low tan δ (< 60×10 -4 )and high breakdown voltage(>5MV/m).The influencing mechanism of various components on the dielectric properties of BTZ ceramics is studied,thus providing the basis for preparation of capacitor ceramics with high ε , low tan δ and high breakdown voltage.更多还原
