Description

Reflection-absorption electronic spectroscopy was applied to measuring the electronic absorption spectra of Ce3+ ions corresponding to 4f→5d transition in 2CsClNaCl, 2CsCl-NaCl-NaF, LiF-NaF and LiF-NaF-ZrF4 melts. The variations in the absorption spectra of cesium ion in the systems mentioned are due to changes in the composition of complex species and their symmetry. Dissolution of Ce2O3 in fluoride melts follow chemical mechanism. Solubility of Ce2O3 in LiF-NaF melt at 940 K was estimated

Abstract (Russian)

Методом отражательно-абсорбционной электронной спектроскопии получены электронные спектры поглощения ионов Ce3+, соответствующие переходу 4f→5d, в расплавах 2CsClNaCl, 2CsCl-NaCl-NaF, LiF-NaF и LiF-NaF-ZrF4. Изменение спектров поглощения ионов церия в этих системах связано с изменением состава комплексных группировок и их симметрии. Показано, что растворение Ce2O3 во фторидных расплавах происходит по химическому механизму. Оценено значение растворимости Ce2O3 в расплавах LiF-NaF при температуре 940 К
