Description
Summary:This research employed a conventional solid-state technique to synthesize a novel AgMoVO 6 ceramic material and conducted an analysis of its microwave dielectric properties. The analysis revealed that the sample synthesized at 520 °C possessed a monoclinic structure and belonged to the C2/m (12) space group, indicating a pure AgMoVO 6 phase. The dielectric constant of the ceramic was primarily influenced by its density, porosity, and ionic polarizability. Moreover, an increase in the packing fraction and lattice energy significantly enhanced the Q  ×  f values of the ceramic. The correlation between the bond valence of the specimen and its τ f value was found to be strong. Furthermore, the study demonstrated that the dielectric characteristics of the specimens were highly dependent on their unit-cell volume, which critically affected their microwave dielectric properties. Notably, the phase-pure AgMoVO 6 ceramic exhibited exceptional dielectric properties at microwave frequencies, with an ε r of ~ 12.4, Q  ×  f of ~ 21,300 GHz, and τ f of ~ –46.9 ppm/°C. Additionally, the ceramic material has been successfully employed in the design of a dual-band filter, showcasing its potential for utilization in 5G systems.
