    摘要: The present disclosure relates to fusion formable highly crystalline glass-ceramic articles whose composition lies within the SiO2—R2O3—Li2O/Na2O—TiO2 system and which contain a silicate crystalline phase comprised of lithium aluminosilicate (β-spodumene and/or β-quartz solid solution) lithium metasilicate and/or lithium disilicate. Additionally, these silicate-crystal containing glass-ceramics can exhibit varying Na2O to Li2O molar ratio extending from the surface to the bulk of the glass article, particularly a decreasing Li2O concentration and an increasing Na2O concentration from surface to bulk. According to a second embodiment, disclosed herein is a method for forming a silicate crystalline phase-containing glass ceramic.

    摘要: The invention is directed to a glass composition and articles made from the composition that are both polarizing and photorefractive. The glass has, for example, a composition consisting essentially of, in weight percent (“wt. %”) of 70-73 SiO2, 13-17% B2O3, 8-10% Na2O, 2-4% Al2O3, 0.005-0.1% CuO,
