Title: Characterization of Microphase-Separated Disordered Materials Using Solid State NMR

Abstract of Research Project

Many disordered materials for technological applications are phase separated on the micro- or nanoscale. A prominent example are bioactive glasses and glass-ceramics what find use in restorative surgery and as body implants. To optimize the chemical and mechanical properties of these biomaterials in an efficient manner, controlled crystallization of initial glass-ceramic compositions is induced in glasses by thermal treatment. I will use solid state NMR techniques to identify intermediate phases formed during the crystallization process at various annealing temperatures and to analyze the local coordination environments of the different nuclei. The application of NMR is favourable because of its well-proven ability to provide structural information on disordered materials and glasses and its element selective and inherently quantitative character.
