Abstract

An electrode holder for use in a furnace for melting a batch material to form molten glass is disclosed comprising a refractory coated nose member presented to and in contact with a molten glass material contained within the furnace. The refractory coating is preferably a flame- or plasma-sprayed ceramic such as alumina or zirconia. That protects the nose member from corrosion from the hot molten glass.

Description

[0001] Cross References to Related Applications [0002] Pursuant to Title 35, United States Code, Section 120, this application claims the benefit of priority to US Application Serial No. 13 / 094,182, filed April 26, 2011, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an improved electrode holder for use during glass melting operations, and more particularly, the present invention relates to a refractory barrier deposited on the front of the electrode holder in contact with molten glass layer (refractory barrier layer). Background technique [0004] The use of metals as well as conductive oxides and non-metallic materials such as carbon as electrodes to resist melting of glass is a realized technology. It is very common to use molybdenum (Mo), carbon or tin oxides with cylindrical or rectangular cross-sections as electrode materials. The problem with using these materials, especially Mo, is that they a...
