摘要

The (1-x)(0.7ZnNb₂O₆-0.3Zn₃Nb₂O₈)-xZnAl₂O₄ (x=0~10%, ZZZ) microwave dielectric ceramics were prepared by the conventional solid-state reaction process. The phase composition, microstructure and microwave dielectric properties of the ZZZ ceramics were investigated. The results show that the ZZZ ceramics can be sintered into porcelain at 1 150 ℃, forming a multiphase structure in which ZnNb₂O₆, Zn₃Nb₂O₈ and ZnAl₂O₄ coexist without appearance of new phases. At microwave frequency, the dielectric constant of ZZZ ceramics is 21 to 24, and the product of quality factor and frequency (Q×f) is 30 000 GHz to 85 000 GHz. With the increase of ZnAl₂O₄ content, the microwave dielectric constant, Q×f value, and temperature coefficient of resonance frequency of ZZZ ceramics decrease, and the temperature stability improves.
