Abstract

A phase pure Ba(Mg1/2Mo1/2)O3 (BMM) ceramic was prepared by a traditional solid-state reaction method with a double perovskite structure (Fm-3 m), which is confirmed by X-ray diffraction. The scanning electron microscope image of the BMM sample confirmed the presence of dense grains and clear grain boundaries. The Raman and far-infrared reflection spectra were measured, and the lattice vibrational modes were analyzed in detail. The intrinsic properties were fitted by the four-parameter semi-quantum model based on the far-infrared spectrum, whose values (εr = 4.728, tanδ = 4.594 × 10–4) were analogous to the theoretical values (εr = 4.290, tanδ = 5.962 × 10–4) calculated by the Clausius–Mossotti (C–M) and damping equations, as well as the measured values (εr = 4.468, tanδ = 4.439 × 10–4).
