초록

The $(Ba_{0.5}Sr_{0.5})(Nb_{0.5}Ti_{0.5})O_3$ [BSNT] ceramics were prepared by conventional mixed oxide method. The structural properties of the BSNT ceramics with sintering temperature were investigated by XRD, SEM, EDS. Increasing the sintering temperature, diffraction intensity of the BST(110) peak was increased. The average grain size of BSNT ceramics were increased with sintering temperature. In the case of BSNT ceramics sintered at 1550$^{\circ}C$, the grain was uniform and the pore was not existed. Increasing the sintering temperature from 1400$^{\circ}C$ to 1500$^{\circ}C$, the amount of Nb and Sr were decreased. The density of BSNT ceramics sintered at 1550$^{\circ}C$ was $1.125g/cm^2$.
