A02: Time-resolved WAXS studies on the crystallization of Al13 keggin clusters
- Polynuclear aluminium species (Al13 keggin cluster) find application in different areas like water purification, contaminant transport, and as pilling clays with high specific surface areas, due to their strong binding ability to aggregates and high positive charge. In the present contribution, we report on the in situ investigation of the Al13 sulfate synthesis by synchrotron wide-angle X-ray scattering (WAXS). Al13 cluster were crystallized by precipitating hydrolyzed aluminum solutions by the addition of sodium sulfate. The measurements were performed using a custom-made acoustic levitator as sample holder. The study provides information about the intermediates during the crystallization process. From the data, a mechanism was derived indicating the influence of the crystallization process.
