Refractory Metals for Glass Technology
Glass melts reach temperatures at which steel corrodes and the melt itself attacks most metals. Electrodes, stirrers or bushings that work directly in the melt need materials that neither oxidise nor get wetted by the molten glass.
Which Material for Which Function
Molybdenum
High corrosion resistance against most glass melts combined with good machinability: the standard material for melting electrodes, stirrers and bushings.
Tungsten
Highest melting point of all metals: melting electrodes for the hottest glass and specialty-alloy melts.
Ceramics
Chemically inert towards glass melts, no wetting: melting crucibles and linings that must remain non-conductive.
Components in Everyday Use
- Melting electrodes for E-glass and specialty glass
- Stirrers in glass melting furnaces
- Bushing plates for glass fibre production
- Crucible linings for laboratory melts
Why Refracore. Molybdenum electrodes and bushings are among the materials we most frequently supply in custom formats — including consultation on alloy selection for particularly aggressive glass compositions.
