In this study, to develop low temperature sintering capacitor composition ceramics with the good dielectric properties, (Ba0.86Ca0.14)(Ti0.85Zr0.12Sn0.03)O3 (BCTZ) ceramics were prepared by the conventional solid-state reaction method. The effects of B2O3 addition on the dielectric properties and microstructure was investigated. The XRD patterns demonstrated that all the specimens showed Perovskite phase, and secondary phases are indicated in the measurement range of XRD. And also, temperature coefficient of capacitance(TCC) of all the specimen sintered at 1,180℃ showed +3∼-56% except for x=0.006. For all the specimens, observed one peak was tetragonal cubic difuse phase transition temperature(Tc), which is located in the vicinity of room temperature.
