| Abstract: | This study investigates the evaporation and deposition of iodine from lead–bismuth eutectic (LBE) systems with iodine mole fractions of 10–5 to 10–3, crucial for the safety of LBE-cooled nuclear reactors. Combining thermosublimatography, morphological analysis and thermodynamic calculations, it identifies PbI2 and BiI3 as the two primarily deposited species, while revealing BiI disproportionation. This work provides novel insights into iodine speciation, emphasizing its importance for the safety of LBE-cooled reactors and gives input for advancing experimental setups and modeling approaches for complex nuclear systems.
