Title: HIGH REFRACTIVE INDEX TITANIUM-NIOBIUM PHOSPHATE GLASS
Abstract:
Disclosed herein are TiNb-phosphate glasses that present several advantages over traditional Ti-phosphate glass compositions. The glasses disclosed herein have a low devitrification tendency and can be processed by melt quenching and formed into macroscopic components. Despite the presence of niobium, the glasses have high stability indices and are chemically durable. The glasses disclosed herein are transparent and have high refractive indices, as well, making them suitable for optical applications.
