A perovskite-like layer-structured compound, Ce2Ti2O7, was prepared in the argon atmosphere using solid reaction process. Single phase and dense Ce2Ti2O7 ceramic was fabricated by high-pressure sintering at 4 GPa and 1100 degrees C. This compound is unstable in oxygen/air when temperature is above 400 degrees C, but it is stable under argon/vacuum. Differential scanning calorimetry result shown Ce2Ti2O7 has a phase transition at 1073 degrees C, which might be the Curie point. The ferroelectricity of Ce2Ti2O7 was confirmed by the piezoelectric activity after poling (d(33) = 0.4 +/- 0.2 pC/N) for the first time.
