| Abstract;The (1-x)MgTiO3-xBaTiO3 (x=0.02-0.1) ceramics were fabricated by the conventional mixed oxide method. The structural and microwave dielectric properties were investigated by the XRD, SEM, EDS and network analyzer. The sintering temperature and time were 1275.DEG.C.-1350.DEG.C., 2 hours, respectively. In the XRD results of (1-x)MgTiO3-xBaTiO3 ceramics, the hexagonal BaMg6Ti6O19 and ilmenite MgTiO3 structures were coexisted. In the case of the 0.9MgTiO3-0.1BaTiO3 ceramics sintered at 1325.DEG.C., dielectric constant, quality factor and temperature coefficient of resonant frequency were 32.67, 32665, -84.5ppm/.DEG.C., respectively.
