Abstract

The structure and dielectric properties of CaCu₃Ti ₄O₁₂ ceramics have been investigated. The starting CaCu₃Ti₄O₁₂ powers were synthesized by a modified glycine nitrate process. The ceramics obtained exhibit a cubic perovskite structure. Dielectric constant up to 57,200 and dielectric loss of 4.4% at 1 kHz have been observed at room temperature. The dielectric properties have been investigated using an impedance spectroscopy technique. The effect of processing and microstructure on the dielectric properties has been discussed.
