Problems solved by technology

[0005] However, for glass substrates for FPDs whose alkali metal components are limited to a small amount, or alkali-free glass that does not substantially contain alkali metal components, the electrical resistance is high. electric heating), it is necessary to enlarge the electrode
At this time, platinum, which has conventionally been used as an electrode for direct electric heating, is a rare metal and is expensive, so there is a cost problem when increasing the size of the electrode.

Embodiment Construction

[0031] Hereinafter, one embodiment of the present invention will be described with reference to the drawings. It should be noted that the following description relates to an example of the present invention, and the present invention is not limited thereto.

[0032] (1) Overall composition

[0033] Hereinafter, as one embodiment of the manufacturing method of the glass of this invention, the manufacturing method of the glass plate for glass substrates of a flat panel display is demonstrated.

[0034] (1-1) Glass raw material

[0035] In order to produce glass panes according to the invention, glass raw materials are first mixed according to the desired glass composition. For example, when producing a glass substrate for a flat panel display, especially a liquid crystal display (LCD), it is suitable to mix the raw materials so as to have the following composition.

[0036] (a) SiO 2 : 50% by mass to 70% by mass,

[0037] (b)B 2 o 3 : 5% by mass to 18% by mass,

[0038] ...

Abstract

The invention provides a method for manufacturing glass. The method can prolong life of a furnace which is provided with walls with electrodes. In the method for manufacturing glass, glass raw materials are imported into a melting furnace so that the glass is melted. The melting furnace is provided with walls built by at least a pair of electrodes 200 and more than two refractory bricks 111c. Composition of raw materials of an electrode 201a forming the electrodes 200 comprises stannic oxide. The method for manufacturing glass is characterized in that the electrodes are kept by using the refractory bricks 111c around in a manner that the electrode 201a can be moved, and the electrode 201a is kept in a preset position in a front end.

Description

[0001] This application is a divisional application, and the Chinese national application number of the application it targets is 201210265450.4, the filing date is July 27, 2012, and the invention name is "glass manufacturing method". technical field [0002] The present invention relates to a method of manufacturing glass. Moreover, this invention relates to the manufacturing method of the glass substrate for flat panel displays (FPD), especially the glass substrate for liquid crystal displays (LCD). Background technique [0003] Conventionally, the radiant heat of the gas flame and the direct energization method have been used as the heating method of the molten glass in the glass melting furnace. In the direct energization method, the molten glass is energized between opposing electrodes, and the molten glass is heated by Joule heat generated at the time of energization. [0004] In the production of the glass of the glass substrate for the FPD, the gas flame and the di...
