Abstract

The 0.96$MgTiO_3$-0.04$BaTiO_3$ ceramics were prepared by the conventional mixed oxide method. The structural properties were investigated with sintering temperature and composition ratio by XRD, SEM and EDS. According to the X-ray diffraction patterns of the 0.96$MgTiO_3$-0.04$BaTiO_3$ ceramics, the hexagonal $BaMg_6Ti_6O_{19}$ and ilmenite $MgTiO_3$ structures were coexisted. In the case of the 0.96$MgTiO_3$-0.04$BaTiO_3$ ceramics sintered at 1325$^{\circ}C$, dielectric constant, quality factor and temperature coefficient of resonant frequency were 23.95, 70,200, -55.8ppm/$^{\circ}C$, respectively.
