Abstract

This research employed a conventional solid-state technique to synthesize a novel AgMoVO6 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 AgMoVO6 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 τf 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 AgMoVO6 ceramic exhibited exceptional dielectric properties at microwave frequencies, with an εr of ~ 12.4, Q × f of ~ 21,300 GHz, and τf 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.
