Abstract

The CaCu3Ti4O12 (CCTO) and (1−x) CaCu2.9Zn0.1Ti4O12–xAl2O3 (0 ≤ x ≤ 0.02) ceramics were prepared via a conventional solid-state method. X-ray diffraction shows that (1−x) CaCu2.9Zn0.1Ti4O12–xAl2O3 ceramics sintered at 1110 °C for 6 h has a CCTO single phase. For the SEM studies of (1−x) CaCu2.9Zn0.1Ti4O12–xAl2O3 ceramics, the 0.985 CaCu2.9Zn0.1Ti4O12–0.015 Al2O3 ceramics has the largest average grain size, followed by CaCu2.9Zn0.1Ti4O12, 0.99 CaCu2.9Zn0.1Ti4O12–0.01 Al2O3, 0.98 CaCu2.9Zn0.1Ti4O12–0.02 Al2O3, CCTO, finally 0.995 CaCu2.9Zn0.1Ti4O12–0.005 Al2O3. When x = 0.015, the dielectric constant is 54,774, the dielectric loss is 0.18 at 1 kHz at room temperature, the grain boundary resistance (Rgb) is 4.7 × 104 Ω and the grain resistance (Rg) is 5.42 Ω. The variation of the loss tangent (tanδ) value of all the samples is consistent with the change of grain boundaries resistance. The results indicate that the nano-Al2O3 doping, which can increase the dielectric constant, has a promising application in enhancing dielectric properties of CCTO.
