Abstract

Objectives : The analysis of present material is to reveal the effect of Fe atom by replacing the Ti atom in CCTO for chemical properties. Methods: Pure and Fe doped CaCu3Ti4-xFexO12 (x=0.05, 0.10, and 0.15) CCTO ceramics were synthesized by solid-state reaction route and calcination was done at 930°C for 12 hrs with heating rate of 4°C/min. The phase structure of samples was confirmed by X-ray Diffraction (XRD) and found single phase calcium copper titanate. Morphology of all samples was investigated by scanning electron microscopy. Absorption band have been also recorded for all samples. Findings: The structure remains cubic by doping of Fe atom in place of Ti atom. The average size of all the samples were lies between 1-1.3µm. Novelty: The bond strength becomes stronger as the doping of Fe atom takes place. The large absorption band is found in the range 380-700 cm-1. The peak of large band is shifted towards lower wave number. These higher wavelengths can be used in water pollutants. The increased volume size of samples shows lower energy band gap. This lower energy band gap enhanced the electrical properties.
