摘要： A method for preparing quartz glass with low content of hydroxyl and high purity, includes providing silica powders including hydroxyl groups. The silica powders are dehydroxylated, which includes drying the silica powders at a first temperature, heating the silica powders up to a second temperature and introducing a first oxidizing gas including halogen gas, thereby obtaining first dehydroxylated powders, and heating the first dehydroxylated powders up to a third temperature and introducing a second oxidizing gas including oxygen or ozone, thereby obtaining second dehydroxylated powders. The second dehydroxylated powders are heated up to a fourth temperature to obtain a vitrified body. The vitrified body is cooled to obtain the quartz glass with low content of hydroxyl and high purity. The quartz glass prepared by the above method has low content of hydroxyl and high purity. A quartz glass with low content of hydroxyl and high purity is also provided.

摘要： The present invention provides for synthesizing high optical quality multicomponent chalcogenide glasses without refractive index perturbations due to striae, phase separation or crystal formation using a two-zone furnace and multiple fining steps. The top and bottom zones are initially heated to the same temperature, and then a temperature gradient is created between the top zone and the bottom zone. The fining and cooling phase is divided into multiple steps with multiple temperature holds.

摘要： 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.

摘要： A display cover is provided. The display cover includes a first glass and a second glass; a carbon material layer disposed between the first glass and the second glass, wherein the carbon material layer is formed by simultaneously applying a heat treatment process to an organic adhesive layer, the first glass, and the second glass to carbonize the organic adhesive layer. The structural strength of display cover can be strengthened by placing a carbon material layer between two glass layers to achieve a strong chemical bond between the thin carbon material layer disposed between the two glass layers and the two glass layers.

摘要： The invention relates to a method to increase the strength of a form body of lithium silicate glass ceramic, which after it has a desired end geometry and after the application of a material which influences its surface to form a coating, is subject to a heat treatment. To create a surface compressive stress through the replacement of lithium ions by alkali ions of greater diameter at least that region not covered by the application layer is covered by a melt or paste consisting of or containing a salt of an alkali metal with ions of greater diameter and the form body is in contact with the melt or paste for a period of time t at a temperature T and the melt or paste is subsequently removed from the form body.
