The effect of sintering atmosphere on the structure and dielectric properties of Bi₂O₃–ZnO–Ta₂O₅ (BZT) system material has been investigated. The study shows that the sintering atmosphere has little effect on the phase structure for Bi₂O₃–ZnO–Ta₂O₅ system; the dielectric constants of the samples sintered in N₂ are larger than those sintering in air; the dielectric loss at low frequency increases and the microwave quality factor (Qf) decreases when sintered in N₂. Furthermore, the temperature dependence of dielectric constant decreases subtly when sintered in N₂.
