Abstract Full text About this article

Dense microwave dielectric ceramics of Ce2[Zr1-x(Al1/2Ta1/2)x]3(MoO4)9 (CZMAT) (x = 0.02-0.10) were prepared by the conventional solid-state route. The effects of (Al1/2Ta1/2)4+ on their microstructures, sintering behaviors, and microwave dielectric properties were systematically investigated. On the basis of the X-ray diffraction (XRD) results, all the samples were matched well with Pr2Zr3(MoO4)9 structures, which belonged to the space group R3¯c. The lattice parameters were obtained using the Rietveld refinement method. The correlations between the chemical bond parameters and microwave dielectric properties were calculated and analyzed by using the Phillips-Van Vechten-Levine (P-V-L) theory. Excellent dielectric properties of Ce2[Zr0.94(Al1/2Ta1/2)0.06]3(MoO4)9 with a relative permittivity (ɛr) of 10.46, quality factor (Q × f ) of 83,796 GHz, and temperature coefficient of resonant frequency (τf) of -11.50 ppm/℃ were achieved at 850 ℃.

Abstract

Dense microwave dielectric ceramics of Ce2[Zr1-x(Al1/2Ta1/2)x]3(MoO4)9 (CZMAT) (x = 0.02-0.10) were prepared by the conventional solid-state route. The effects of (Al1/2Ta1/2)4+ on their microstructures, sintering behaviors, and microwave dielectric properties were systematically investigated. On the basis of the X-ray diffraction (XRD) results, all the samples were matched well with Pr2Zr3(MoO4)9 structures, which belonged to the space group R3¯c. The lattice parameters were obtained using the Rietveld refinement method. The correlations between the chemical bond parameters and microwave dielectric properties were calculated and analyzed by using the Phillips-Van Vechten-Levine (P-V-L) theory. Excellent dielectric properties of Ce2[Zr0.94(Al1/2Ta1/2)0.06]3(MoO4)9 with a relative permittivity (ɛr) of 10.46, quality factor (Q × f ) of 83,796 GHz, and temperature coefficient of resonant frequency (τf) of -11.50 ppm/℃ were achieved at 850 ℃.
