ABSTRACT:
A method of treating a waste material, such as a radioactive waste material, by introducing the material into a high temperature reaction vessel such as an electric arc furnace. By controlling the reducing potential of the oxide phase formed in the reaction vessel, the concentration of the waste material in the oxide phase can be controlled. In addition, the morphology of the oxide phase can be controlled so that once the concentration of the waste material in the oxide phase is adjusted as desired, the waste material can be sequestered within the crystal lattice of the cooled oxide phase for subsequent disposal.
