Abstract

One of the future technologies in nuclear reactors is the ability of piezoelectric materials to monitor reactor cores as sensors. Particularly, Pb-free piezoelectric materials, such as Bi_1/2Na_1/2TiO₃, have been examined to improve the ability of their piezoelectric properties. In this study, we attempted to add Pr₆O₁₁ dopant material with mole ratios of 0, 0.3, 0.5, and 0.7 mol%. The synthesis process used in this study is the molten-salt synthesis method with a NaCl and KCl salt mole ratio of 1:1. The crystal structure analysis using the refinement process of the Rietveld method of the HighScore software was performed. Accordingly, a rhombohedral crystal structure system with lattice parameters of 3.8809(2), 3.8831(2), 3.8834(7), and 3.8816(2) angstroms and variations in the content of Pr₆O₁₁ was obtained. The optimal lattice parameter was discovered with the addition of 0.5 mol% of Pr₆O₁₁. The morphology of the synthesis product is still unclear for each addition of dopant material due to the large number of granular agglomerations.
