Ag(Nb0.6Ta0.4)O-3 (ANT) ceramics were synthesized by conventional solid-state method and wet chemical method (sol-gel method). The effects of preparation methods on synthesis temperature, phase structure, morphology, Raman spectra, and dielectric properties of ANT ceramics were investigated. For sol-gel method, K2CO3 was used to dissolve Nb2O5 and Ta2O5, avoiding use of strong corrosive hydrofluoric acid. The results showed that the synthesis temperature of ANT phase obtained by sol-gel method was 700 A degrees C, while that by solid-state method was 950 A degrees C. The nanopowders around 40 nm were obtained by sol-gel method, while the micro-powders around 1.5 mu m by solid-state method. In addition, the decrease of vibration frequency of A(1g)(O) stretch mode indicated that the Nb-O or Ta-O bonds became weak, which lead to high permittivity. The dielectric properties of the ceramics prepared by the two methods were different. Notably, the dielectric loss (6.6 x 10(-4)) of ANT ceramic synthesized by sol-gel method was much lower than that (22.8 x 10(-4)) by solid-state method.
