Synthesis of Ba(Zr,Ti)2O5 particles using Zr/Ti-HPA with complexing of Ti-IPA and Zr using ZrOCl2
For this study, Zr-substituted BaTi2O5 particles were synthesized using an aqueous solution method with peroxidized polytitanic acid as the starting material. After Zr/Ti heteropolyacids were synthesized by complexing Zr with polytitanic acid (Ti-IPA) in aqueous solution using ZrOCl2, the obtained Zr/Ti heteropolyacids were mixed with barium hydroxide. Subsequently, the precipitate was dried and heat-treated at 1100 °C for 10 h. Thereby, we obtained single-phase Ba(Zr,Ti)2O5 powder. Using this method, BaTi2O5 was synthesized with up to 6 mol% Zr solid solution on Ti sites. These results were evaluated using XRD and XRF. The crystal structure and structural transition of the resulting Ba(Zr,Ti)2O5 were evaluated using Raman measurements. All Ba(Zr,Ti)2O5 samples showed a structural transition. The Curie temperatures Tc of BaTi2O5, BaZr0.034Ti0.966O5, and BaZr0.059Ti0.941O5 were, respectively, 480, 450, and 430 °C.
