The effect of 9Bi_2O_3-CuO mixed oxides as sintering agent on sintering behaviors and dielectric properties of Ba_(0.6)Sr_(0.4)TiO_3 (BST) ceramics were investigated. It was found that 9Bi_2O_3-CuO mixed oxides lowered the sintering temperature about 300℃ and that highly denser BST ceramic pellets were obtained by sintering at 975℃ with addition of 5,0-10.0wt% mixed oxides. For BST ceramics with 5.0wt% CB content sintered at 975℃, had a moderate dielectric constant (ε=1315), low dielectric loss (0.0067) and high tunability (36%) at dc electric field of 20kV/cm and at room temperature and at 10kHz.
