From: High wettability of liquid caesium iodine with solid uranium dioxide
Cross-sectional observation results following sessile drop method testing between solid UO2 and liquid CsI. The sample was at the maximum temperature with liquid CsI for 1 minute in maximum. (a) SEM image and EDX mapping images of (b) I, (c) Cs and (d) U. Observations noted deep infiltration of liquid CsI into the solid UO2 on a macroscopic scale by way of the pores network present in the polycrystalline structure. Scale bar is 20 μm.
