Substantially alkali free glasses are disclosed with can be used to produce substrates for flat panel display devices, e.g., active-matrix liquid crystal displays (AMLCDs). The glasses have high annealing temperatures and Young's modulus. Methods for producing substantially alkali free glasses using a downdraw process (e.g., a fusion process) are also disclosed.

High strain point and high young's modulus glasses

Glass-based articles that include a reduced Young's modulus layer extending from a surface of the glass-based article to a depth of layer and an optional compressive stress layer extending from a surface of the glass-based article to a depth of compression are formed by exposing glass-based substrates to water vapor containing environments. The methods of forming the glass-based articles may include elevated pressures and/or multiple exposures to water vapor containing environments. The glass-based articles may be utilized in foldable or flexible electronic devices.

Glasses with modified young's modulus profile

A glass composition includes from 60 mol % to 76 mol % SiO; from 7 mol % to 16 mol % AlO; from 0 mol % to 12 mol % BO; and from 0 mol to 14 mol % NaO. (RO+RO)/AlOin the glass composition may be greater than or equal to 1. A glass laminate article includes a core glass layer having a low temperature coefficient of thermal expansion (LTCTE) and a high temperature coefficient of thermal expansion (HTCTE): a clad glass layer laminated to a surface of the core glass layer, the clad glass layer having a low temperature coefficient of thermal expansion (LTCTE) and a high temperature coefficient of thermal expansion (HTCTE); and a thickness t.

Glass compositions and strengthened glass laminate articles comprising the same

A method of manufacturing a strengthened glass article includes forming a glass-to-glass laminate by fusing clad and core glasses, where the clad has greater high-temperature coefficient of thermal expansion (HTCTE) than the core but a lesser low-temperature coefficient of thermal expansion (LTCTE). The method includes cooling the laminate to impart stresses through contraction mismatch between the clad and core, where stresses in the laminate from HTCTE differences at least partially offset stresses in the laminate from LTCTE. After the cooling, the method includes modifying geometry of the laminate, then relaxing at least some of the stresses in the glass-to-glass laminate from differences in the HTCTE.

Glass laminate articles

Glass-based articles that include a compressive stress layer extending from a surface of the glass-based article to a depth of compression are formed by exposing glass-based substrates to water vapor containing environments.
