| 英文摘要 | (1-x)CoTiNb2O8-xZnNb(2)O(6) microwave dielectric ceramics were prepared via the conventional solid-state reaction route with the aim of reducing the (f) value and improving the thermal stability. The phase composition and the microstructure were investigated using X-ray diffraction, Raman spectra, and scanning electron microscopy. A set of phase transitions which were induced by composition had been confirmed via the sequence: rutile structurecoexistence of rutile and columbite phasecolumbite phase. For (1-x)CoTiNb2O8-xZnNb(2)O(6) microwave dielectric ceramics, the addition of ZnNb2O6 content (x = 0-1) led to the decrease of epsilon(r) from 62.98 to 23.94. As a result of the high Q x f of ZnNb2O6 ceramics, the increase of ZnNb2O6 content also led to the lower sintering temperatures and the higher Q x f values. The (f) value was reduced from +108.04 (x = 0) to - 49.31 ppm/degrees C (x = 1). Among them, high density 0.5CoTiNb(2)O(8)-0.5ZnNb(2)O(6) ceramics were obtained at 1175 degrees C with excellent microwave dielectric properties of epsilon(r) 39.2, Q x f 40013 GHz, and (f)+3.57 ppm/degrees C. |
