Abstract: Ag(Nb_0.8Ta_0.2)O₃(ANT) powders were synthesized by using different solid-state reaction methods. The samples were characterized by XRD and SEM. In addition, the dielectric
properties of some good ceramic samples were tested. The results showed that different methods almost had no influence on the perovskite structure, but
affected the microstructure greatly. The ceramics obtained by the method, in which Nb₂O₅ and Ta₂O₅ were firstly sintered at 1200℃
and then reacted with Ag₂O, showed a uniform particle distribution and higher density. Compared with the other methods, the dielectric properties
of the samples prepared by this method were improved, the dielectric constant (ε) was increased and the dissipation factor (tgδ) was decreased.
