Abstract
The synthesis of CaCu3Mn4O12 (CCMO) has been accomplished via solid-state reaction. The mixture was calcined at 850 C-0 for 12 hours. Temperature of 1090 degrees C has been chosen with 6 differ soaking time ranging from 1 hour to 24 hours. The CCMO formation was confirmed using X-ray diffraction (XRD). The microstructure analysis was carried out using field emission scanning electron microscopy (FESEM), while electrical properties have been studied using AutoLab PGSTAT 30 Frequency Analyser. Results shows that differ soaking time for sintering introduce unique properties for CCMO. Microstructural analysis reveal that soaking time more than 12 hours produce grains with almost uniform shape. The physical densification of the sintered pellets promotes the creation of new conduction channels and increase of intergrain effective area for transport current under conductivity properties. Results for bulk conductivity vary from 0.2148 x 10(-4) to 0.5825 x 10(-4) S/cm.
