Research Equipment: Instrumentation for Measuring Ionic Conductivities and Mobilities of Solids and Solid - Fluid Interfaces

提供设备以发展两个流固相互作用动力学研究领域的研究能力。其中一个项目集中在β-氧化铝家族的离子迁移率和交换性质上。具体的研究涉及用于水电解的质子传导性和用于核废料管理的离子交换。第二项研究考察了玻璃从水蒸气或水溶液中水合的速度。这项研究的实际目标也与危险材料的处置有关，因为已经提出了各种玻璃形式作为高放核废料的容器基质。这两项研究都要求对离子浓度和迁移率进行实验测定。该装置由频响分析仪、电化学接口、阻抗分析仪等部件组成。

Equipment is provided to develop research capability for two areas of study of the kinetics of fluid-solid interactions. One project is focused on the ionic mobilities and exchange properties of the family of beta-aluminas. Specific investigations have to do with proton conductivity for water electrolysis and with ion exchange for nuclear waste management. A second study examines the rates at which glasses are hydrated from vapor or aqueous solutions. The practical objectives of this study are also associated with disposal of hazardous material, since various glass forms have been proposed as containment matrices for high-level nuclear waste. These investigations both call for experimental determinations of ionic concentration and mobilities. The equipment consists of a frequency response analyzer, electro-chemical interface, impedence analyzer, and other components.
