A laminated sheet includes a surface layer having an optical surface that is of fire-polished quality and a core layer having a higher modulus than the surface layer to increase an overall stiffness or fracture toughness of the laminated sheet.

High-strength laminated sheet for optical applications

Disclosed are laminated glass articles and methods of making the same.

Laminated glass articles and methods of making thereof

The subject matter disclosed herein generally relates to glass compositions for protecting glass and methods of making and using the compositions.

Glass compositions for protecting glass and methods of making and using thereof

Glasses are disclosed which are used to produce substrates in flat panel display devices. The glasses exhibit a density less than about 2.45 gm/cmand a liquidus viscosity greater than about 200,000 poises, the glass consisting essentially of the following composition, expressed in terms of mol percent on an oxide basis: 65-75 SiO, 7-13 AlO, 5-15 BO, 0-3 MgO, 5-15 CaO, 0-5 SrO, and essentially free of BaO. The glasses also exhibit a strain point exceeding 650&#xb0; C.

Glasses for flat panel displays

A semiconductor-on-insulator structure including first and second layers which are attached to one another either directly or through one or more intermediate layers. The first layer includes a substantially single crystal germanium semiconductor material while the second layer comprises a glass or a glass-ceramic material having a linear coefficient thermal of expansion (25-300&#xb0; C.) which is within the range of +/&#x2212;20&#xd7;10/&#xb0; C. of the linear coefficient thermal of expansion of the germanium first layer.

Germanium on glass and glass-ceramic structures

A method of determining parameters of plurality of thermal cycles to achieve a set glass strain level includes providing a plurality of input parameters for a glass substrate and a plurality of parameters for a plurality of thermal cycles. The method also includes iteratively modifying at least one of the pluralities of thermal cycle parameters so the glass strain is not greater than the set glass strain level after a final thermal cycle is completed. An aspect of the method usefully enables a user to determine from the material parameters and processing sequences of the glass manufacturer and further entities that may further process the glass (e.g., the glass manufacturer's customers) whether a particular glass strain can be achieved; and if not the example embodiments allows the manufacturer to calculate changes in the customers' processes to meet the desired glass strain.

Method of optimizing glass strain

Glasses are disclosed which are used to produce substrates in flat panel display devices. The glasses exhibit a density less than about 2.45 gm/cmand a liquidus viscosity greater than about 200,000 poises, the glass consisting essentially of the following composition, expressed in terms of mol percent on an oxide basis: 65&#x2013;75 SiO, 7&#x2013;13 AlO, 5&#x2013;15 BO, 0&#x2013;3 MgO, 5&#x2013;15 CaO, 0&#x2013;5 SrO, and essentially free of BaO. The glasses also exhibit a strain point exceeding 650&#xb0; C.

A method of measuring the shape of a glass sheet is provided. The method includes positioning the glass sheet in contact with a fluid and measuring the distance between a sensor and a surface of the glass sheet at a plurality of locations on the surface thereof. The method may further include deconvolving the shape of the glass sheet into at least one simple shape element, such as cylindrical or spherical, and may further include varying the temperature profile of an array of heaters in a glass manufacturing process based on the at least one shape element.

Process and apparatus for measuring the shape of an article

A glass laminate substrate for electronic substrates, such as flat panel displays, includes a transparent glass core bounded by transparent glass skin layers, wherein the coefficient of thermal expansion of the core is greater than the coefficient of thermal expansion of the skin layers thereby forming a residual compressive stress in the skin layers and a residual tensile stress in the core. The relative thickness of the skin layers can be selected to enhance the strength of the glass laminate substrate while maintaining a sufficiently low residual tensile stress in the core to allow scribing and separating of the substrate to size. Interlayers can be located between the core and the skin layers, wherein the interlayers include a residual compressive stress, and produce a reduced residual tensile stress in the core.

A glass-ceramic material which exhibits extremely low (e.g. less than 100 ppm) shrinkage, when exposed to 900&deg; C. for 6 hours, and methods for making such glass-ceramics. The glass-ceramic is cerammed at a sufficiently high temperature and then cooling in a controlled manner, preferably to below the strain point of the resultant material. Using this technique, glass-ceramic materials were fabricated which exhibited dimensional shrinkage comparable to and in some cases even less than that achieved by fused silica substrates, when exposed to high temperature poly-Si processing temperatures (e.g. 900&deg; C. for 6 hours).
