Structural Analysis of Pure and Magnesium Doped Barium Titanate Ceramic

This research focuses on the synthesis and analysis of barium titanate samples, both pure and magnesium-doped, using the sol-gel auto combustion method. The samples were categorized into three groups with the chemical formula Ba1-xMgxTiO3, where x takes values of 0.00, 0.10, and 0.20. Through X-ray diffraction patterns, the formation of a perovskite structure with a singular phase was confirmed in all samples. Notably, the pure barium titanate sample exhibited a prominent absorption peak at 495 cm-1, while the doped composites with x values of 0.10 and 0.20 displayed absorbance peaks at 497 cm-1 and 499 cm-1, respectively. The use of Fourier Transform Infrared spectroscopy and Field Emission Scanning Electron Microscopy corroborated the presence of polycrystalline microstructures, characterized by a measurable degree of porosity that aligns well with X-ray diffraction analysis. Particle distribution demonstrated a normal distribution pattern. Energy Dispersive Spectroscopy further confirmed the elemental composition, revealing the presence of Ba, Ti, and O, as well as minimal traces of Mg impurities. This study underscores the successful synthesis and characterization of Ba1-xMgxTiO3 samples, contributing to the understanding of their structural and compositional properties.
