In this paper the dielectric properties of (0.8-x)Pb(Mb$_{1}$3//Nb/2/3)O$_3$/BaTiO$_3$-CaZrO$_3$(x=0.1, 0.15, 0.2, 0.25) ceramics were investigated. Specimens were prepared by the conventional mixed oxide method and sintering temperature and time were 1000~115$0^{circ}C$ 2hr, respectively. The structural and dielectric properties with variation of sintering temperature and composition were investigated. All the specimens sintered at 115$0^{circ}C$ for 2hr showed the highest value of 1043. With increasing the contents of CZ and frequency dielectric constant was decreased and which was decreased with increasing temperature from 3$0^{circ}C$ to 15$0^{circ}C$.
