摘要 | Microwave dielectric ceramics of Ba[Zn(1-x)/3Ni x/3Nb2/3]O3 (BZNN, x = 0.0, 0.5, 0.6, 0.7, 0.8) were sintered at 1773 K (1500 C) for 3 hours by the conventional solid-state reaction method. To clarify the relationship between dielectric properties and crystal structures, vibration spectra (Raman spectroscopy and Fourier transform far-infrared reflection spectroscopy (FTIR)) and X-ray diffraction (XRD) were employed to study Ba[Zn(1-x)/3Nix/3Nb2/3]O 3 solid solutions. Crystal structures were determined as cubic perovskite structures, and no phase transition appears in substitution of Ni2+ to Zn2+ ions. Raman spectroscopy was used to discuss the correlation of dielectric properties with Raman shifts and full-width at half-maximum (FWHM) values, which indicate that dielectric properties are closely related to both FWHM values and A1g(Nb) mode shifts. FTIR spectra and imaginary parts of dielectric constants were calculated to obtain the correlation between polar phonon modes and dielectric properties with Ni2+ concentration. © 2012 The Minerals, Metals & Materials Society and ASM International. |
