- Abstract
Mixture of zinc metatitanate and rutile (ZnTiO3 + 0.2TiO2), had been prepared via the conventional solid-state reaction method. The sintering behavior and microwave dielectric properties of ZnO–TiO2 system were investigated. The composition and microstructure of ceramics were discussed with XRD and SEM. It was found that ZnO–TiO2 ceramics, which was sintered at 900°C using 1.0 wt% B2O3 as sintering additive, had homogeneously fine microstructures and high densification. Samples possessed excellent microwave dielectric properties: εr = 26, Q × f = 34,890 GHz, and τf = −11 ppm/°C. The above- mentioned material was suitable for the tape casting process and compatible with Ag electrodes, therefore, was an excellent candidate for multilayer ceramic capacitor applications.
