Abstract
In various embodiments, refractory-metal glass melt electrodes are single-crystalline, at least within an outer layer thereof.
Claims20
A glass melt electrode comprising:
- a base sized and shaped for engagement with an interior surface of a glass-melting furnace;
- and
- an elongated shaft extending from the base,
- wherein at least an outer surface layer of the shaft is single-crystalline and comprises one or more refractory metals.
1 more element
A method of processing glass, the method comprising:
- providing a glass-melting furnace, wherein one or more glass melt electrodes protrude from an inner wall of the glass-melting furnace into an inner volume of the glass-melting furnace;
- disposing glass material within the inner volume of a glass-melting furnace;
- and
- melting the glass material at least in part by applying electrical current to the one or more glass melt electrodes, each glass melt electrode being at least partially immersed in the melted glass material,
- wherein at least an outer surface layer of each of the glass melt electrodes is single-crystalline and comprises one or more refractory metals, the one or more glass melt electrodes resisting corrosion during the melting of the glass material.
