Abstract
Disclosed herein are glasses that present several advantages over traditional glass compositions used in optical applications. The glasses disclosed herein have a low devitrification tendency and can be processed by melt quenching and formed into macroscopic components. The glasses have high glass thermal stability indices and are chemically durable. The glasses disclosed herein are transparent when heat treated in air or oxygen and have high refractive indices and low density, as well, making them suitable for optical applications.
