研究了B2O3添加剂对固相法制备的ixolite结构ZnTiNb2O8陶瓷烧结性能、微观结构和微波介电性能的影响。B2O3添加剂作为助烧剂，由于液相的形成，可以有效地将ZnTiNb2O8陶瓷的烧结温度降低到1050℃。在整个实验过程中，XRD结果几乎没有观察到第二相。系统地研究了ixiolite-structure ZnTiNb2O8陶瓷介电常数（epsilon(r)）和品质因子（Q.f）随B2O3用量和烧结温度的变化。随着B2O3添加量的增加，epsilon(r)和Q.f减小，谐振频率温度系数（tau(f)）在-20 ppm/℃附近略有波动。高epsilon(r)近似于35.04，Q.f近似于50,100 GHz时的最佳微波介电性能。ZnTiNb2O8陶瓷在1050℃下烧结得到了接近于零的τ (f)，接近于20.21 ppm/℃。相对较低的烧结温度和微波范围内较高的介电性能使ZnTiNb2O8陶瓷在电子领域具有广阔的应用前景。(C) 2016 Elsevier B.V.版权所有
The effects of B2O3 additives on the sintering behavior, microstructure and microwave dielectric properties of ixiolite-structure ZnTiNb2O8 ceramics prepared by conventional solid-state route were investigated. The B2O3 additives, acting as a sintering aid, can effectively decrease the sintering temperature of ZnTiNb2O8 ceramics to 1050 degrees C, due to the formation of liquid phase. Little second phase from XRD results was observed throughout the entire experiments. The variations in the dielectric constant (epsilon(r)) and quality factor (Q.f) of the ixiolite-structure ZnTiNb2O8 ceramics were studied systematically depending on the adopting of B2O3 and the sintering temperatures. With the increase of the B2O3 addition, epsilon(r) and Q.f decreased and the temperature coefficient of resonant frequency (tau(f)) slightly fluctuated around -20 ppm/degrees C. The optimal microwave dielectric properties with high epsilon(r) similar to 35.04, Q.f similar to 50,100 GHz, and a near-zero tau(f) similar to-20.21 ppm/degrees C were obtained at 1 wt%-B2O3-doped samples sintered at 1050 degrees C. The relatively low sintering temperature and high dielectric properties in microwave range would make ZnTiNb2O8 ceramics promising for application in electronics. (C) 2016 Elsevier B.V.
