초록

$Ba(Zn_{1-x}Co_x)TaO_3$[BZCT] ceramics were prepared by the conventional mixed oxide method. The ceramics were sintered at the temperature of $1450{\sim}1550^{\circ}C$ for 5hr. in air. The structural properties of the BZCT ceramics as a function of composition and sintering temperature were investigated by the XRD and SEM. The crystal structure of BZCT ceramics was investigated by the XRD. The microstructure of the specimens were observed by SEM. All the BZCT ceramics sintered above the $1550^{\circ}C$ were showed as a polycrystalline complex perovskite structure without second phases and any unreacted materials. The density of BZCT (70/30) specimen sintered at $1550^{\circ}C$ was $6.31g/cm^3$.
