We have examined the formation of aluminosilicate in high alkaline and salt concentrated solutions characteristic of nuclear tank wastes. Information on the mechanism and kinetics of the phase formation under hydrothermal conditions was obtained by characterization the structures of gel phases as a function of time and composition using multinuclear NMR techniques in combination with x-ray diffraction. This work offers a new insight into the aluminum and aluminosilicate chemistry in simulated nuclear tank wastes.
