Abstract

(1 - x) NiZrNb2O8 - x ZnTa2O6 microwave dielectric ceramics were prepared via the conventional solid-state reaction route. Structural and lattice parameters of the (1 - x) NiZrNb2O8 - x ZnTa2O6 ceramics were analyzed through X-ray diffraction, Raman spectra, and scanning electron microscopy. The results showed that there were serious ionic diffusion and solid solution reaction in the composite ceramics. The substitution of Ni2+, Zr4+, and Zn2+ at A-sites and the substitution of Nb5+ and Ta5+ at B-sites led to the change of the lattice parameters. There was a gradual transformation in crystal structure from monoclinic phase into Tri-alpha PbO2 phase with the increasing ZnTa2O6 content. With the increase of x value from 0 to 1, the epsilon (r) value increased from 23.76 to 35.71 and the Q x AE' value increased from 32107 to 46709 GHz. The temperature frequency resonance coefficient near zero could be obtained at x = 0.8. The 0.2NiZrNb(2)O(8) - 0.8ZnTa(2)O(6) ceramics were obtained at 1275 A degrees C with excellent microwave dielectric properties: epsilon (r) similar to 33.69, Q x AE' similar to 37,529 GHz and tau(AE') similar to + 2.56 ppm/A degrees C.
