The Dielectric Properties of CaCu₃Ti₄O₁₂at Various Calcination Temperatures

Abstract:

High dielectric constant of CaCu₃Ti₄O₁₂ (CCTO) has drawn a great deal of intention these past years as potential material for capacitor and even micro-electronic applications. In this research, an attempt has been made to investigate the relationship between the calcination temperature and the dielectric properties of CCTO. The calcination of CCTO at lower temperature (below 1000^○C) provides incomplete reaction process, where the secondary phase is detected on the sample. Calcination at 1040^○C provides a single phase as just same with the control sample (sample which had gone through both phase calcine and sinter). It is also found that calcination at 1040^○C provides the dielectric properties that almost the same with the calcine-sinter sample.
