## Description

- description: Containerless processing was used to access and study supercooled liquids
    and glasses that cannot be made using conventional melting approaches. In-situ
    measurements of melt atomic structure and density provided insight into how the
    glass forms. Experiments included making measurements in microgravity where buoyancy
    driven convection and sedimentation are suppressed. Here we examine the structure
    and properties of rare earthaluminate composition liquids and some glasses made
    from them. The structures show a fundamentally different network behavior from
    the classical Zachariasen model. The network comprises four and about 40% five
    coordinated aluminum ions that share corners or edges and often form triply bonded
    species with an oxygen ion. The concept of Kn is used to evaluate the glass forming
    behavior in terms of network connectivity and bonding. The temperature dependence
    of density of the liquid is reported and discussed in the context of processing
    molten materials in reduced gravity where bubbles can be trapped in the liquid
    due to lack of buoyancy. The interior structure in samples was investigated using
    X-ray tomography to investigate how bubbles can cluster inside a liquid drop.
