Publication number: 20220009814Abstract: Apparatus and methods are disclosed for forming a glass article in which molten glass is heated in a refractory vessel by establishing an electrical current in the molten glass between opposing powered electrodes along a first electrical path. The melting vessel includes a precious metal component in contact with the molten glass, and at least one non-powered electrode proximate the precious metal component. The at least one non-powered electrode and the precious metal component form second and third electrical paths, respectively, in parallel with the first electrical path such that an electrical current in the second electrical path is decreased, thereby reducing an electrochemical reaction in the precious metal component.Type: ApplicationFiled: September 20, 2019Publication date: January 13, 2022Inventors: Samir Biswas, Aaron Joshua Hade, David Myron Lineman, Steven Robert Moshier, Nicholas Scott Ryan

Patent number: 9868663Abstract: A glass ceramic precursor glass and a glass ceramic having low levels of rhodium and a method of controlling the amount of rhodium in such glasses and glass ceramics. The precursor glass and glass ceramic contain from about 1 ppm to about 10 ppm and, in certain embodiments, from about 1 ppm to about 6 ppm rhodium. The method of controlling of reducing rhodium dissolution from a rhodium-containing material such as, for example, an alloy into a glass melt comprises controlling and/or lowering the partial pressure of oxygen at the rhodium-containing vessel/glass interface by imposing a high humidity condition around the external (non-glass-contact) surface of the rhodium-containing material. The lower concentration of rhodium minimizes its coloring effect on the white color of the glass ceramic.Type: GrantFiled: July 1, 2016Date of Patent: January 16, 2018Assignee: CORNING INCORPORATEDInventors: Samir Biswas, Qiang Fu, David Myron Lineman, Ronald Leroy Stewart

Patent number: 9475723Abstract: A mold for shaping glass can be made by a method that includes providing a mold body having a shaping surface comprising at least about 90% nickel and modifying the composition of the shaping surface of the mold body by exposing the shaping surface to an oxidizing heat treatment. The oxidizing heat treatment may include a ramping heat treatment, a fixed heat treatment, or both the ramping heat treatment and the fixed heat treatment. The ramping heat treatment may include increasing a heating temperature at a rate from about 20° C./hour to about 500° C./hour to a temperature from about 700° C. to about 1000° C. The fixed heat treatment may include holding the heating temperature from about 700° C. to about 1000° C. for a holding time of at least about 5 minutes.Type: GrantFiled: August 26, 2015Date of Patent: October 25, 2016Assignee: Corning IncorporatedInventors: Kristen Marie Horn, David Myron Lineman, Kevin Thomas Morris, Wenchao Wang, Kim E.

Patent number: 9475720Abstract: Hydrogen may permeate into an interior space of an article in response to molten glass being in contact with the outer surface of the article. The permeation may be restricted by having a fluid in a length of the interior space. The fluid may be in contact with the inner surface of the article, the fluid may fill at least about 33% of the volume of the length of the interior space, and the fluid may provide a predetermined partial pressure of hydrogen. Features may be provided for causing the fluid to flow within the interior space.Type: GrantFiled: November 26, 2012Date of Patent: October 25, 2016Assignee: CORNING INCORPORATEDInventors: David Myron Lineman, Martin Herbert Goller, Steven Robert Moshier

Patent number: 9382145Abstract: A precious metal structure which has an internal gas permeable membrane is described herein for a glass manufacturing vessel configured to have molten glass flow therein. The internal gas permeable membrane can be supplied with an atmosphere of gas (or gases) to control the flux of hydrogen into our out of the molten glass or otherwise improve the production of the molten glass. In this manner, the undesirable detrimental reactions that can occur at the interface of the molten glass and precious metal interface which can cause defects in the molten glass such as bubbles or solid inclusions can be stopped or at least substantially reduced.Type: GrantFiled: June 30, 2015Date of Patent: July 5, 2016Assignee: Corning IncorporatedInventors: Martin Herbert Goller, David Myron Lineman, Randy Dean Ziegenhagen

Patent number: 9309139Abstract: 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.Type: GrantFiled: February 13, 2014Date of Patent: April 12, 2016Assignee: Corning IncorporatedInventors: Andrea Weiss Bookbinder, Bryce Patrick Butler, Gilbert De Angelis, David Myron Lineman, Guido Peters
