Abstract:

In this study, ceramic composites of the Zn2Te3O8–TiTe3O8 system were adopted to improve the dielectric properties of the ultra-low-fire single-phase Zn2Te3O8. The ceramic composites were densified at 600°C. The X-ray diffraction results show no interaction between Zn2Te3O8 and TiTe3O8 during sintering. Granular grains in the range of 1–5 m were observed, and the microstructural evolution was nearly independent of the TiTe3O8 content. Owing to the inertness between Zn2Te3O8 and TiTe3O8 ceramics, the dielectric constant (r) and the temperature coefficient of resonant frequency (f) increased nearly linearly, while the quality factor (Q×f) decreased with the content of TiTe3O8 in the Zn2Te3O8 ceramic. The Zn2Te3O8–30 wt% TiTe3O8 ceramic composite sintered at 600°C reported the best dielectric properties with an r of 19.8, a Q×f of 50 042 GHz (at a measurement frequency of 11.8 GHz), and a f of 3.0 ppm/°C, qualifying the ultra-low-fire composites for use in ceramic resonators.
