Microwave Dielectric Properties of the Binary System BiNbO₄–FeNbO₄

Abstract

The microwave dielectric properties of BiNbO4–FeNbO4 ceramics prepared by the conventional solid-state reaction method, and co-fired at low temperature, had been investigated. The structure, phase composition and surface morphology were studied by X-ray diffraction and scanning electron microscopy techniques, respectively. The dielectric properties of the prepared samples were determined at ≈2.8 GHz, using the modified resonant cavity perturbation method, which accuracy was previously studied using typical cylindrical samples of polytetrafluorethylene. The experimental dielectric constant values of the samples were then fitted to the theoretical curves of different mixture laws.

“…And lastly also in 2020, Devesa et al 15 described the dielectric properties of the BiNbO 4 -FeNbO 4 ceramic at 2.8 GHz microwave band using the resonance cavity model, Furthermore, they used scanning electron microscopy and X ray diffraction to obtain the phase composition and morphology of the structure, thus enabling possible applications in microwave devices such as antennas, filters and others.…”
