  • In this study, the dielectric properties of (Sr$\sub$1-x/Ca$\sub$x/)TiO$_3$+yNb$_2$O$\sub$5/(0.1 x 0.3, 0.004 y 0.008) ceramic capacitor were investigated. The specimen was sintered for 3hr at 1350$^{\circ}C$ in gas(N$_2$) atmosphere. The reduced specimen fared at 1200$^{\circ}C$ in air. The used specimens had the apparent permittivity of 3${\times}$10$^4$∼4${\times}$10$\^$5/, tan$\delta$ of 0.05 -0.2, and insulating resistance of 10$\sub$9/∼10$\^$12/ $\Omega$.cm. The specimens had the stable temperature coefficient of capacitance.
