The optimization of dielectric properties for high dielectric perovskite-like ceramics is a research hotspot. (NaLn)Cu3Ti4O12 (Ln=Ce; Nd) dielectric ceramicswere prepared by ahigh-temperature solid-state methodat different sintering temperatures. The phase characteristics, microstructure and dielectric properties of the dielectric ceramics were investigated. The results show that (NaLn)Cu3Ti4O12 (Ln=Ce; Nd) ceramics are single-phase ceramics. The dielectric constant of (NaLn)Cu3Ti4O12 ceramics increasesand the dielectric loss changeswith the increase of sintering temperature. Different doping ions caninduce the corresponding polarization mechanism, further causingdifferent dielectric properties. (Na1/3Ce2/3)Cu3Ti4O12 ceramics prepared at 1 000 ℃ havethe higher dielectric properties, i.e., ε=50 552 at 10 Hz. However, the dielectric loss of (Na1/2Nd1/2)Cu3Ti4O12 ceramics prepared at 950 ℃ is smaller, i.e., tanδ=0.09 at 10 Hz.
