Synthesis and characterization of Barium Titanium Oxides (BaTiO3) Single perovskite Annealed by Different Temperatures
In this paper, the conventional solid state interaction method was used to prepare BaTiO3 single perovskite samples, which were heated to a different annealing temperatures from 0 to 800 into 1200 degrees. The optical properties of the samples were investigated, using Fourier transformation infrared (FT-IR) and Ultraviolet visible (UV-Vis) spectroscopies. Whilst, UV-visible results were exhibited and explicit data of UV-visible which was used to evaluate the absorption, transmission, reflection, extension and energy band gaps. It's found that the effect of the annealing of samples' temperature on the extinction coefficient (k) decreased while the temperature was increasing. In addition, the reflection was directly proportional to the temperature. In this case, the materials turned closely into which is called a mirror. The increasing of energy band gap (Eg) is related to increasing in an annealing temperature. This transition was indirected and thereupon, "the phenomenon" uses especially, for the industrial devices, to convert materials from insulator to semiconductors. Furthermore, the chemical bonds within atoms were investigated and verified by FTIR data in this paper.
