Abstract
Microwave dielectric properties of ZnO–MgO–TiO2–CaO (ZMTC) ceramics were investigated as a function of sintering temperatures by the conventional solid-state method. Sintering characteristics, microstructures, and microwave dielectric properties of ZMTC ceramics were studied as a function of sintering temperature from 1210 to 1290 °C. The variation trend of εr and Qƒ value was in accordance with variation trend of relative density. With increasing sintering temperature, the density, εr and Qƒ values increased, saturating at 1230 °C with excellent microwave properties of εr = 22.5, Qƒ = 22.1 × 104 GHz, and TCF = 23.1 ppm/°C.
