Web1 dec. 2024 · With increasing particle size, there is a more significant separation between the Mo particle and the UO 2 matrix. Fig. 4 (d) shows the interfacial debonding between UO 2 and Mo particles. The 150 μm Mo particle composite has cracks, and the large interfacial debonding can result in reduced thermal conductivity. 3.3.
