Abstract

Dissociation kinetics of thorium oxide (ThO2) on the surface of free surface tungsten was analyzed using numerical model and Auger electron spectroscopy (AES). It was found that enthalpy of the system decreased upon dissociation of the ThO2 on the free surface due to high binding energy of the oxygen to the free W surface. It was observed that the dissociation rate of thorium oxide was neither governed by diffusion nor y a usual thermally activated process. The results show that the evolution rate of thorium surface segregation is much faster at 0.11 μA/cm2.
