【 摘 要 】

The task assigned to PI David London, University of Oklahoma, was to devise hydrothermal methods of synthesis that optimize the size of synthetic monocrystals of alkali feldspars, KAlSi3O8 (orthoclase) and NaAlSi3O8 (albite). The synthesis method agreed upon will utilize convention cold-seal hydrothermal reactors. This equipment and synthesis method were chosen for two reasons: (1) the method best simulates hydrothermal reactions of silicate glass waste material with groundwater, and (2) the method employs small, sealed volumes of reagents, which minimizes potential hazards when and if radionuclides are added to the system. Note that the University of Oklahoma did not approve the award for acceptance until November 20, 2001.
