1.发明申请HIGH VOLUME PRODUCTION OF DISPLAY QUALITY GLASS SHEETS HAVING LOW ZIRCONIA LEVELS 有权具有低ZIRCONIA级别的显示质量玻璃板的大批量生产公开(公告)号：US20140230491A1
公开(公告)日：2014-08-21
申请号：US14179857
申请日：2014-02-13
Applicant: Corning Incorporated
Inventor： Andrea Weiss Bookbinder , Bryce Patrick Butler , Gilbert De Angelis , David Myron Lineman , Guido Peters
CPC classification number: C03B5/225 , C03B5/027 , C03B5/16 , C03B5/1675 , C03B5/185 , C03B5/43 , Y02P40/57
Abstract: 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.
