Gadolinium Oxide Dissolution Kinetics in Chloride GdCl3-KCl Melt According to Raman Spectroscopy Data
https://doi.org/10.47612/0514-7506-2022-89-3-341-347
Abstract
Using in situ Raman spectroscopy, the chemical mechanism of gadolinium oxide dissolution in the GdCl3-KCl melt is established. The changes in the normalized intensities of the vibrational bands is used to determine the kinetic parameters of the ongoing chemical reaction. It is established that the concentration of the reagent — gadolinium oxide — decreases with time according to an exponential law, the order of the reaction with respect to Gd2O3 is the first. It is shown that the introduction of gadolinium oxide into the melt in an amount exceeding its solubility leads to the formation of a solid phase of gadolinium oxychloride GdOCl.
