Ca{sub 2}Ce{sub 2}Ti{sub 5}O{sub 16} ceramics processed via mix oxide route was investigated. Phase composition and microwave dielectric properties were measured using X-ray diffraction and a cavity method, respectively. CeO{sub 2} and another unidentified phase (that vanishes at ≥1400°C) existed as secondary phases along with the parent Ca{sub 2}Ce{sub 2}Ti{sub 5}O{sub 16} phase. The amount of the parent Ca{sub 2}Ce{sub 2}Ti{sub 5}O{sub 16} phase increased with increasing sintering temperature from 1350°C to 1450 °C accompanied by a decrease in the apparent density. The density decreased but ε{sub r} and Qufo increased with sintering temperature. An ε{sub r} ∼87.2, Qufo ∼5915 GHz and τ{sub f} ∼219 GHz was achieved for the sample sintered at 1450°C.
