Notes:
The effects of CuO-MoO3 addition on the sintering behavior and microwave dielectricproperties of ZnO-TiO2 ceramics were investigated. ZnO-TiO2 ceramics were prepared with conventionalsolid-state method and sintered at temperatures from 850 to 1050 °C. The sintering temperature ofZnO-TiO2 ceramics with CuO-MoO3 addition could be effectively reduced to 950 °C due to the liquidphase effects resulting from the additives. A proper amount of CuO-MoO3 addition could effectivelyimprove the densification and microwave dielectric properties of ZnO-TiO2 ceramics. ZnO-TiO2ceramics with 3 wt% addition sintered at 950 °C for 4 h exhibited better microwave dielectric propertiesas follows: εr of 26.8, a Q×f value of 16780 GHz at 5.42 GHz, and a τf value of +34.7 ppm/°C
