Abstract

BaTi₄O₉ (BT4) calcined at 1150°C and Ba(Mg_1⁄3Ta_2⁄3)O₃ (BMT) calcined at 1200°C are mixed, the sintering and the microwave dielectric characteristics of 0.18 mol BT4 and 0.82 mol BMT ceramics are determined (BT4-BMT). The required sintering temperature of BT4-BMT ceramics is decreased to approximately 1320°C. As the sintering temperatures increase from 1240 to 1360°C, the microwave dielectric properties of BT4-BMT ceramics change as follows: The ε_r values increase from 23.5 to 28.0, the Q*f values increase from 25200 to 64700 and the τ_f values linearly change from 2.0 ppm/°C to 4.3 ppm/°C. The ε_r values, the Q*f values and the τ_f values are saturated in 1320°C-sintered ceramics.
