摘要： An improved slot down-draw process for forming glass sheets having a thickness less than 200 μm from glass formulations that have melting points near or above 1200° C. is provided. The improvements allow easier maintenance of the slot assembly and better management of the thermal expansions experienced by some components of the slot down-draw system.

摘要： Apparatuses and methods are described for controlling the width and thickness of glass during glass sheet production. The apparatuses and methods employ a gas cooling mechanism that is designed to extract heat from molten glass during the drawdown process to reduce width attenuation and generate more uniform glass. In some examples, a nozzle of a glass forming apparatus includes a first nozzle portion with a first glass forming surface, and a second nozzle portion opposite the first nozzle portion, where the second nozzle portion includes a second glass forming surface opposite the first glass forming surface. The nozzle also includes a first cavity within the first nozzle portion, and a second cavity within the second nozzle portion. Gas, such as air, is delivered to each of the first cavity and the second cavity to cool molten glass as it is drawn between the first and second glass forming surfaces.

摘要： A powder useful for making a mold utilized for shaping glass-based materials includes at least about 50% by weight nickel. Metal oxides that are not miscible with nickel may be dispersed within the powder in an amount in a range from about 0.2 to about 15% by volume. A mold made from the powder may have a mold body having a composition comprising at least 50% by weight nickel and a metal oxide that is not miscible with nickel in an amount in a range from about 0.2 to about 15% by volume, a nickel oxide layer on a surface of the mold body wherein the nickel oxide layer has first and second opposing surfaces, the first surface of the nickel oxide layer contacts and faces the surface of the mold body, the second surface of the nickel oxide layer includes a plurality of grains, and the plurality of grains has an average grain size of about 100 μm or less.
