Abstract |
CaCu3Ti4O12 (CCTO) powders were prepared by sol-gel process using acetic acid as a solvent and also as cross-linking agent by varying the sintering temperature (1000-1150oC) for 3 h. The dried gels were characterized by TG-DTA and FT-IR techniques. The sintered samples were characterized by XRD, SEM techniques and impedance analyzer for dielectric properties measurement. All samples showed CCTO perovskite structure with small amounts of TiO2 and CuO phases. The best dielectric properties (εr = 1.38 104 and tanδ = 0.13 at 10 kHz and room temperature) were observed in the CCTO pellets samples calcined at 800ºC for 3 h and sintered at 1100ºC for 3 h. |
