Glass compositions and methods for strengthening via steam treatment
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. The methods of forming the glass-based articles may include elevated pressures and/or multiple exposures to water vapor containing environments.
Method of strengthening glass using plasma torches and/or arc jets, and articles made according to the same
Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li.sup.+, K.sup.+, Mg.sup.2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.
Method for producing a blank of fluorine-doped and titanium-doped glass having a high silicic-acid content and a blank produced according to the method
A method for producing a silica glass blank co-doped with titanium and fluorine for use in EUV lithography includes (a) producing a TiO.sub.2SiO.sub.2 soot body by flame hydrolysis of silicon- and titanium-containing precursor substances, (b) fluorinating the TiO.sub.2SiO.sub.2 soot body to form a fluorine-doped TiO.sub.2SiO.sub.2 soot body, (c) treating the fluorine-doped TiO.sub.2SiO.sub.2 soot body in a water vapor-containing atmosphere to form a conditioned soot body, and (d) vitrifying the conditioned soot body to form the blank. The blank has an internal transmission of at least 60% in the wavelength range of 400 to 700 nm at a sample thickness of 10 mm, a mean OH content in the range of 10 to 100 wt. ppm and a mean fluorine content in the range of 2,500 to 10,000 wt. ppm. Titanium is present in the blank in the oxidation forms Ti3.sup.+ and Ti.sup.4+.
Methods of making colored glass by surface modification
A method of making colored glass in a float glass process includes the steps of: melting glass batch materials in a furnace to form a glass melt; transporting the glass melt into a float glass chamber having a flame spray device, the glass melt forming a float glass ribbon; supplying at least one coating material to the flame spray device to form a spray having coating particles; and directing the spray onto the float glass ribbon to diffuse the particles into the surface of the float glass ribbon to form a glass sheet of a desired color.
Method for treating glass containers comprising an optical check of a quantity of treatment substance dispensed, and related treatment installation
The invention relates to a method for treating the wall of a glass container (1), which wall delimits a cavity (4) and an opening providing access to said cavity (4), the method comprising: the dispensing of a treatment substance into the cavity, using a dispensing means (12) of which a dispensing orifice (13) is positioned some distance from the opening of the container (1) and outside the latter, the container (1) being in motion relative to the dispensing means (12), and the capturing, by an image-capturing device (16), during the dispensing, of at least one image of a spatial region including the opening of the container (1) and determining, by analysing said image, whether or not a predetermined quantity of substance was introduced into the cavity (4) of the container (1). Method and installation for treating glass containers.
Glasses with modified young's modulus profile
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.
