摘要

The evaporation behaviour of tellurium from liquid lead–bismuth eutectic was investigated using the transpiration method in an inert atmosphere between 220 and 600 °C. The results showed a significant retention of Te within the LBE matrix compared to the vapour pressure of pure Te. The temperature dependence of the Henry’s law volatility constant above 350 °C was determined using data from this study and compared with data reported in the literature. A noticeable deviation from linearity was observed at temperatures below 350 °C, possibly due to surface enrichment phenomena connected to chemical reactions enhancing Te volatilisation, highlighting the need for further investigation at lower temperatures.
