A borosilicate-based composition, including: 50-85 mol. % SiO, 10-40 mol. % BO, >0-5 mol. % SnO, and >0-20 mol. % of at least one alkali oxide selected from LiO, NaO, KO, RbO, and CsO, such that the composition has a Young's Modulus less than 64 GPa.

Phase-separated glass compositions

Methods for manufacturing glass articles having a target effective coefficient of thermal expansion CTEaveraged over a temperature range comprise selecting a glass core composition having an average core glass coefficient of thermal expansion CTEthat is greater than the target effective CTEand a glass clad composition having an average clad glass coefficient of thermal expansion CTEthat is less than the target effective CTE; and manufacturing a glass laminate comprising a glass core layer formed from the glass core composition and two or more glass cladding layers fused to the glass core layer, each of the two or more glass cladding layers formed from the glass clad composition such that a ratio of a thickness of the glass core layer to a total thickness of the two or more glass cladding layers is selected to produce the glass laminate having an effective coefficient of thermal expansion CTEthat is within ±0.5 ppm/° C. of the target effective CTE.

Ion-exchanged alkali aluminosilicate glass articles with a ratio of peak compressive stress value to Young's modulus value of 14 or more. The glass articles may include AlOmol %+RO mol %≥18 mol %, where RO mol %=MgO mol %+CaO mol %, and be substantially free of ZnO, SrO, BaO, BO, PO, LiO, and KO. The glass articles may have a peak compressive stress value in a range of 850 MPa to 1400 MPa. The glass articles are suitable for various high-strength applications, including cover glass applications that experience significant bending stresses during use, for example, cover glasses for flexible displays.

Low-modulus ion-exchangeable glasses

According to one embodiment, a glass may include from about 50 mol. % to about 70 mol. % SiO; from about 12 mol. % to about 35 mol. % BO; from about 4 mol. % to about 12 mol. % AlO; greater than 0 mol. % and less than or equal to 1 mol. % alkali metal oxide, wherein LiO is greater than or equal to about 20% of the alkali metal oxide; from about 0.3 mol. % to about 0.7 mol. % of NaO or LiO; and greater than 0 mol. % and less than 12 mol. % of total divalent oxide, wherein the total divalent oxide includes at least one of CaO, MgO and SrO, and wherein a ratio of LiO (mol. %) to (LiO (mol. %)+(NaO (mol. %)) is greater than or equal 0.4 and less than or equal to 0.6. The glass may have a relatively low high temperature resistivity and a relatively high low temperature resistivity.

An article comprises a glass substrate. The glass substrate has a first surface having a plurality of vias therein, and a second surface parallel to the first surface. At least one of the first surface and the second surface is an etched surface having a surface roughness (Ra) of 0.75 nm or less. The glass substrate comprises, in mol percent on an oxide basis: 65 mol %&#x2264;SiO&#x2264;75 mol %; 7 mol %&#x2264;AlO&#x2264;15 mol %; 26.25 mol %&#x2264;RO+AlO&#x2212;BO; 0 mol %&#x2264;RO&#x2264;2 mol %.
