Kinetics and Mechanism in the Oxidation of Thorium and Uranium

Abstract

The results of a laboratory investigations which involve (1) the vaporization of Thorium metal using rf heating, laser radiation heating by chemical reactions, and (2) the oxidation of thorium and Uranium, are presented. It has been , determined that the heat of vaporization for monoatomic thorium vapor is 143 Kcal/mole. The ionization potentials of Thorium (gas) and Thorium oxide (gas) are quite low (5.5 -6.0eV), while that of thorium dioxide (ThO2) is higher by 3eV. The rate constant for the production of thorium dioxide ion (ThO2+) was determined. The results of the laser blow-off study indicate that the spectrum from uranium metal produces both netural and singly ionized uranium atoms.
