| Abstract |
Sn4+ doped CaCu3Ti4.1−xSnxO12 (x = 0.00, 0.05, and 0.10) ceramics were prepared using a one-step polymer pyrolysis method. Variation of Δε′ < ± 15% over a temperature range of − 60 to 210 °C, very low tanδ ~ 0.009–0.012 and giant-ε′ ~ 6685–14,194 at 30 °C and 1 kHz were achieved in ceramics with x = 0.05 and 0.10 sintered at 1080 °C for 7 h. Furthermore, tanδ values of less than 0.03 and Δε′ < ± 10% over wide temperatures range of − 60 to 150 °C and − 60 to 200 °C were obtained in each of the ceramics. Both ceramics are promising candidate materials for X9R capacitor and X-P capacitor applications. The increase of grain boundary resistance (Rgb) with increasing Sn4+ content in the presence of a TiO2 phase are suggested to play an important role in extending Δε′ < ± 15% and tanδ < 0.05 over a wider temperature range. |
