Effects of BaWO4 additive on Raman phonon modes and structure–property relationship of Ba(Mg1/3Ta2/3)O3 microwave dielectric ceramics

Preparation, characterization, and dielectric properties of wolframite-structure MnZrNb 2 O 8 ceramics at microwave frequency

“…They were widely applied in mobile and satellite M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 2 communications such as filters, dielectric resonators and antennas due to a high Q·f, an appropriate ε r and a near-zero τ f [2,3]. Many dielectric ceramics also have been reported with excellent properties possibly used for practical application [4][5][6][7][8].…”

Microwave Dielectric Properties and Sintering Behavior of K20 Series Temperature‐Stable 0.91MgTiO3‐0.09(Ca0.8Na0.1Ce0.1)TiO3 Composite Ceramics

“…While the peaks of MgTiO 3 were too weak to be captured. Besides, Raman vibration mode is an important parameter which related to microwave dielectric properties [19] . Thus, Figure 2(d)–(i) presents the deconvoluted Raman spectra of 0.91MT‐0.09CNCT ceramics sintered at different temperatures.…”

Lattice dynamics and phonon characteristics of complex perovskite microwave ceramics

“…However, it is quite difficult to elucidate the relationship between atomic vibration and dielectric properties. The Raman spectra provide the correlation between vibration characteristics and the properties, even though the Raman phonons are of non-polarised modes [88,[95][96][97]. Based on the Raman shifts and FWHM values of the vibration modes, the relation between the phonon modes and the dielectric properties can be identified.…”
