This research is structural investigation of the nucleation                stage in multianion oxynitride glass ceramic materials, e.g.                    barium-aluminum-silicon oxynitrides, or magnesium-aluminum-                     silicon oxynitrides.  The study will determine, using magic angle               sample spinning nuclear magnetic resonance, the relationship of                 local microstructural units to nucleation phenomena.  Glasses                   processed by conventional melting or by sol-gel techniques will                 be chemically analyzed, and thermal stability and microstructure                will be determined.  Differential thermal analysis, x-ray                       diffraction, small angle x-ray scattering, nuclear magnetic                     resonance, and electron microscopy will be used to characterize                 the specimens.                                                                                                                                                       The research will provide the knowledge base needed to                     fabricate new glass and glass ceramic materials having novel                    combinations of properties.
