CaCu3Ti4O12 (CCTO) has a giant dielectric constant of up to 105 at room temperature and great potential for technological application. In this work, we report two wet-chemistry methods to synthesize CCTO at relatively low temperatures and short reaction times. The pure-phase sample was obtained at 800 °C for 0.5 h, and the grain size of a pellet sample sintered at 1030 °C has a homogeneous distribution in the range of 0.4–1.5 μm.
