| Barium titanate, barium zirconate, and barium hafnate are all essential components of the electroceramic industry. Barium titanate is the most well known member of the perovskite family essentially used for multi-layered ceramic capacitors in computers, aerospace, and communication technologies. Barium zirconate is one of the most inert, stable, and corrosion-resistant perovskite employed in superconducting applications. Hafnium-based oxides are currently leading candidates to replace silicon oxide as a gate insulator in field effect transistors. The goal of this research was to apply a more environmentally benign synthetic design to the production of barium-based perovskites. A method consuming naturally occurring and less toxic precursors while achieving stoichiometric control over the barium-to-X (X= Ti, Zr, Hf, Sn) molar ratio was expanded. Infrared spectroscopy, X-ray powder diffraction, and inductively coupled plasma were used to characterize the products. The synthesis, characterization data, and outcomes are detailed in this poster. |
