摘要：

The effects of Dy2O3 doping on the dielectric properties of (Ba, Sr) TiO3 series capacitor ceramics prepared using solid-state reaction method were studied. With the increasing of Dy2O3 additive, the dielectric constant (epsilon) of materials increases to a maximum when w(Dy2O3) is about 0.5% while the dielectric loss(tandelta) decreases. The BST ceramics with highepsilon ( = 5245), low tandelta( = 0.0026) and high DC breakdown voltage ( = 5.5 mV .m(-1)) were obtained. The influencing mechanism of Dy2O3 on the dielectric properties of (Ba, Sr) TiO3 ceramics was studied, thus providing the basis for preparation of capacitor ceramics.
