Abstract
In this study, in order to develop the capacitor composition ceramics with the good dielectric properties, $(Ba_{1-x}Ca_x)(Ti_{0.85}Zr_{0.12}Sn_{0.03})O_3$ (abbreviated as BCTZ) ceramics were prepared by the conventional solid-state reaction method. The effects of Ca substitution on the microstructure and dielectric properties was investigated. The X-ray diffraction patterns demonstrated that all the specimens showed perovskite phase, and secondary phases are indicated in the measurement range of X-ray diffraction. Also, all the specimens indicated an rhombohedron phase structure. It was identified from the X-ray diffraction patterns that the secondary phase formed in grain boundaries and then decreased the dielectric properties. For all the specimens, observed one peak was tetragonal cubic phase transition temperature($T_c$), which is located in the vicinity of room temperature.
