Description

[0001] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 352,602, filed June 21, 2016, and U.S. Provisional Application Serial No. 62 / 351,616, filed June 17, 2016, herein They are taken as a basis and are hereby incorporated by reference in their entirety, respectively. Background technique [0002] The present disclosure relates to glass-ceramic materials. More specifically, the present disclosure relates to optically transparent glass-ceramic materials. Even more specifically, the present disclosure relates to optically transparent glass-ceramic materials having a crystalline tungsten bronze phase. [0003] Near-infrared (NIR) shielding glasses are developed to block and / or eliminate the 700-2500nm wavelength range for applications such as optical filters, lenses, and glazing for medical, defense, aerospace, and consumer applications. [0004] Low-emissivity (low-E) coatings have been developed to minimize the amount of ult...
