Method for manufacturing belt-shaped glass and device for manufacturing belt-shaped glass

A manufacturing method for a band-shaped glass includes a forming step, which forms a band-shaped glass, an annealing step, which performs an annealing treatment on the band-shaped glass, a cooling step, which cools the annealed band-shaped glass, a direction-changing step, which changes a feeding direction of the cooled band-shaped glass from a longitudinal direction to a horizontal direction, and a horizontal conveying step, which conveys the band-shaped glass in the horizontal direction while supporting the band-shaped glass at a horizontal conveyance part. In the horizontal conveying step, the band-shaped glass is conveyed in the horizontal direction while a first propulsion for driving the conveyance in the horizontal direction is provided at both sides in the width direction of the band-shaped glass by the horizontal conveyance part, the first propulsion being larger than a second propulsion provided at a center in the width direction of the band-shaped glass.

Ultralow expansion titania-silica glass

Annealing treatments for modified titania-silica glasses and the glasses produced by the annealing treatments. The annealing treatments include an isothermal hold that facilitates equalization of non-uniformities in fictive temperature caused by non-uniformities in modifier concentration in the glasses. The annealing treatments may also include heating the glass to a higher temperature following the isothermal hold and holding the glass at that temperature for several hours. Glasses produced by the annealing treatments exhibit high spatial uniformity of CTE, CTE slope, and fictive temperature, including in the presence of a spatially non-uniform concentration of modifier.

Method to increase the strength of a form body of a lithium silicate glass ceramic
11370702 · 2022-06-28 · ·

The invention relates to a method to derive a medical form body of lithium silicate glass ceramic. To increase its strength it is proposed that in the form body comprising lithium silicate glass or containing lithium silicate glass the lithium ions are replaced by alkali ions of greater diameter to generate a surface compressive stress. To this end the form body is covered with a melt containing an alkali metal for which an aliquoted quantity of salt containing the alkali metal is used.
