Preparation of Calcium Titanate Perovskite Compound, Optical and Structural Properties

Abstract

In this work, we have successfully fabricated a calcium titanate perovskite compound. The resulting CaTiO3 compound was studied by preparing samples by compacting it in a powder state and using a Pousson device. The distance between the planes dhkl, Miller indices (hkl), degree of crystallinity and amorphism, structure and lattice parameters of the calcium titanate perovskite compound were determined using an X-ray diffractometer. Also, according to the results of FT-IR analysis, the formation of CaTiO3 perovskite is confirmed as a result of the study of molecular vibrations. The main broad peaks are observed in the range of 680÷400 cm-1, the absorption band at the wave number of 543,93 cm-1 corresponds to the specific stretching vibrations of Ti-O bonds and indicates the formation of the CaTiO3 perovskite type structure implies. Based on the results of these measurements, it will be possible to use semiconductor compounds in the future to create nanofilms by magnetron sputtering.
