“…Feng et al [24] improved the Q•f value by the partial replacement of Zr 4+ by (Al 1/2 Ta 1/2 ) 4+ ions in Ce 2 Zr 3 (MoO 4 ) 9 ceramics. In addition, Ce 2 (Zr 1−x (Mn 1/3 Sb 2/3 ) x ) 3 (MoO 4 ) 9 ceramics [25] and Ce 2 (Zr 1−x (Al 1/2 Nb 1/2 ) x ) 3 (MoO 4 ) 9 ceramics [26] also exhibited good dielectric properties. Therefore, the Zr-site was selected as the site for ion doping instead of choosing Nd-site and Mo-site.…”

Microwave dielectric ceramics (MWDCs) with low dielectric constant and low dielectric loss are desired in contemporary society, where the communication frequency is developing to high frequency (sub-6G). Herein, Nd 2 (Zr 1−x Ti x ) 3 (MoO 4 ) 9 (NZ 1−x T x M, x = 0.02-0.10) ceramics were prepared through a solid-phase process. According to X-ray diffraction (XRD) patterns, the ceramics could form a pure crystal structure with the R3 ¯c (167) space group. The internal parameters affecting the properties of the ceramics were calculated and analyzed by employing Clausius-Mossotti relationship, Shannon's rule, and Phillips-van Vechten-Levine (P-V-L) theory. Furthermore, theoretical dielectric loss of the ceramics was measured and analyzed by a Fourier transform infrared (IR) radiation spectrometer. Notably, when x = 0.08 and sintered at 700 ℃, optimal microwave dielectric properties of the ceramics were obtained, including a dielectric constant (ε r ) = 10.94, Q•f = 82,525 GHz (at 9.62 GHz), and near-zero resonant frequency temperature coefficient (τ f ) = −12.99 ppm/℃. This study not only obtained an MWDC with excellent properties but also deeply analyzed the effects of Ti 4+ on the microwave dielectric properties and chemical bond characteristics of Nd 2 Zr 3 (MoO 4 ) 9 (NZM), which laid a solid foundation for the development of rare-earth molybdate MWDC system. Keywords: microwave dielectric ceramics (MWDCs); Nd 2 (Zr 1−x Ti x ) 3 (MoO 4 ) 9 (NZ 1−x T x M); Phillips-van Vechten-Levine (P-V-L) theory; theoretical dielectric loss
