Description

The interaction of cesium ions with feldspars at 1500C and 2000C has been studied in distilled water, granite groundwater and saline solution. Pollucite, CsAlSi/sub 2/O/sub 6/, was identified by infrared spectroscopy, and was formed as a cubic crystalline phase. Surface analytical techniques (XPS, SAM, SIMS and SEM/EDX) show Cs to be sorbed onto the mineral surfaces and alteration products. The mechanism of pollucite formation and its relevance to cesium transport/retardation in the near field of a nuclear waste-disposal vault is discussed
