Novel" Techniques: Laser Ionization TOF and Aerolevitation

Abstract:
In this talk we will present two techniques that have provided some new capabilities in the characterization (LITOF) and manufacturing (aerolevitation) of exotic glasses. The use of laser ionization combined with time of flight mass spectrometry has yielded several insights on the intermediate range structure of glasses, and we have moved towards quantification in the borate system. Aerolevitation started out as an advanced manufacturing technique that inhibits crystallization and can work at very high temperatures, and thus provides the ability to turn some nearly impossible compositions into glasses. Lately, we have begun an effort to incorporate the ability to detect and quantify crystallization as we cool the levitated beads.
