Glass Melting Electrode

Definition - What does Glass Melting Electrode mean?

Glass melting electrodes act as a fuel source in a glass melting plant, must withstand high melting and electric boosted melting temperatures, and are widely used in the glass manufacturing industry. Glass melting electrodes primarily consist of molybdenum with small quantities of zirconium oxide (ZrO2) added to enhance the properties of these electrodes.

Corrosionpedia explains Glass Melting Electrode

The high temperature strength and rigidity of molybdenum electrodes mixed with small quantities of zirconium oxide along with the inherent electrical properties of molybdenum give glass melting electrodes maximum operating efficiency during glass melting operations in a furnace. Molybdenum glass melting electrodes must have 99.95% purity levels to have outstanding resistance to chemical corrosion and degradation, and to minimize detrimental glass discoloring.

MoZrO2 glass melting electrodes offer a particularly high level of corrosion resistance to glass melts and better creep resistance than pure molybdenum.
