摘要： Methods and apparatus for producing display quality glass sheets are provided in which the batch materials for making the sheets are melted in a furnace whose glass-engaging surfaces comprise zirconia (ZrO2). By using molybdenum electrodes, instead of the conventional tin electrodes, to electrically heat the molten glass, the wear rate per unit area of the furnace's glass-engaging, zirconia-containing surfaces are reduced by more than 50%, thus reducing zirconia levels (solid+dissolved) in the finished glass by at least a similar amount. As a consequence of this reduction, rejection rates of finished glass sheets are lowered, which is of particular value in the production of glass sheets of large dimensions, as desired by display manufacturers and other users of such sheets.

摘要： A submerged combustion melter includes a floor, a roof, and a sidewall structure connecting the floor and roof defining an internal space. A first portion of the internal space defines a melting zone, and a second portion defines a fining zone immediately downstream of the melting zone. One or more combustion burners in either the floor, roof, the sidewall structure, or any combination of these, are configured to emit the combustion gases from a position under a level of, and positioned to transfer heat to and produce, a turbulent molten mass of glass containing bubbles in the melting zone. The fining zone is devoid of combustion burners or other apparatus or components that would increase turbulence above that in the melting zone. The melter may include a treating zone that stabilizes or destabilizes bubbles and/or foam. Processes of using the melters are a feature of the disclosure.

摘要： The invention relates to a method for producing bubble-free glasses, in which a glass mixture that is arsenic-free and antimony-free with the exception of any unavoidable raw material impurities as well as at least one sulphate compound and SnO
2 as refining agents are used. The glass mixture comprising refining agents is melted in a melting tank (1), melting down taking place and a primary refinement being carried out in a first region (10) of the melting tank (1), an average melting temperature (T
1 ) being set at T
1 > 1560 °C and an average melt residence time (t
1 ) being set at t
1 > 2 hours in said first region (10). The proportion of SO
3 resulting from the decomposition of the sulphate compound is reduced to less than 0.002 wt.% as the primary refinement is being carried out. A secondary refinement is carried out in a second region (20) of the melting tank (1), an average melting temperature (T
2 ) being set at T
2 > 1640 °C and an average melt residence time (t
2 ) being set at t
2 > 1 hour in the second region (20).

摘要： A fining agent for reducing the concentration of seeds in a silicate glass. The fining agent includes at least one inorganic compound, such as a hydrate or a hydroxide that acts as a source of water. In one embodiment, the fining agent further includes at least one multivalent metal oxide and, optionally, an oxidizer. A fusion formable and ion exchangeable silicate glass having a seed concentration of less than about 1 seed/cm 3 is also provided. Methods of reducing the seed concentration of a silicate glass, and a method of making a silicate glass having a seed concentration of less than about 1 seed/cm 3 are also described.

摘要： Feed materials (116) are melted in a first vessel (114) to form a glass melt (118) at a first temperature T1, the glass melt containing at least one fining agent. The molten glass is next cooled to a second temperature T2 less than T1 in a second vessel (120) wherein an oxygen-comprising gas is not actively added (e.g. bubbled) into the melt during the duration of the time the melt is at T2. The molten glass is thereafter heated to a third temperature T3 greater than T1 in a third vessel (122) and subsequently formed into a glass article (140).

摘要： A method of controlling blister formation in a glass melt flowing through a system comprising one ore more refractory metal vessels by developing a blister index and determining the critical blister index value. The critical value of the blister index may be used to control the principal variables responsible for blister formation, including the water content of the melt, the concentration of reduced multivalent oxide compounds in the melt, and the hydrogen partial pressure of an atmosphere in contact with the outside surface of the refractory metal vessel. Also disclosed is a minimum partial pressure of hydrogen necessary to produce an essentially blister-free glass article in a glass essentially free of arsenic and antimony.
