Abstract

$BaO-TiO_2$ ceramics ($BaO:TiO_2$=18.2:81.8[mol.%]) were fabricated by mixed-oxide method. Microwave dielectric properties were investigated with sintering temperature and annealing time. Increasing the sintering temperature, the sintered density was decreased. At the sintering temperature of 1400$[^{\circ}C]$, dielectric constant, quality factor and temperature coefficient of resonant frequency had a good values of 35.03, 5690, -4.433$[ppm/^{\circ}C]$, respectively. Increasing the annealing time, dielectric constant and quality factor were increased and temperature coefficient of resonant frequency was decreased.
