Abstract
The effects of additive sintering aids on the microstructures and microwave dielectric properties of 0.85MgTiO3–0.15Ca0.6La0.8/3TiO3 ceramics were investigated. CuO was selected as a liquid phase sintering aid to lower the sintering temperature of 0.85MgTiO3–0.15Ca0.6La0.8/3TiO3 ceramics. With added CuO, the densification temperature of 0.85MgTiO3–0.15Ca0.6La0.8/3TiO3 can be effectively reduced from 1450 to 1160–1300°C. Low-level doping of CuO (0.5–5 wt %) significantly improves the density and dielectric properties of 0.85MgTiO3–0.15Ca0.6La0.8/3TiO3 ceramics. The quality factor Q×f was strongly dependent upon the amount of additives. Q×f values of 60000 and 20000 GHz could be obtained at 1160–1300°C with 0.5 and 5 wt % CuO added, respectively. Over all ranges of addition, the relative dielectric constants differed significantly and ranged from 23.2 to 26.1. The temperature coefficient varied from 0 to -3.7 ppm/°C.
