Levitation yields purer glass

Recent developments regarding the development of REA1 Glass, a new glass which can be used in laser and optical communicatoins applications, are reviewed. The glass contains rare earth oxides, aluminum oxides, and silicon dioxide and is formulated in the Electrostatic Levitator at NASA Marshall Space Center. Because a variety of rare-earth elements can be incorporated into the glass, glasses with specific properties for specific tasks can be crafted.
