advanced molybdenum solutions
The high temperature strength and rigidity of molybdenum glass melting electrodes, plus the inherent electrical properties of molybdenum, provide maximum operating efficiency.
high-performance solutions for the glass industry
We work closely with our glass industry partners to provide molybdenum electrodes in standard sizes and diameters with fast delivery times, along with custom options tailored to unique or project-specific needs. We can machine simple or complex thread forms to precise customer requirements.
capabilities
Elmet Technologies offers high-performance refractory metal products and solutions, with unmatched expertise in the field of powder metallurgy.
molybdenum
Molybdenum material is the best choice for electric heating in the glass melting process. It offers excellent strength and stability at temperatures over 2000°C.
applications
Mo and MoZrO2 electrodes are used in the melting, homogenizing, feeding, and shaping of containers, flat glass, bottles, fiberglass, specialty glass, and more.
materials & Specifications
The materials we use in our electrodes includes: high-purity molybdenum (Mo) and premium molybdenum-zirconium (MoZrO2). Uniquely, we utilize our very own high-quality, high-purity molybdenum powder as the source material. As a fully-integrated manufacturer of molybdenum, this is how we perform rigorous quality control, to ensure unmatched purity and quality for electrodes.
improve furnace
efficiency & operation
Molybdenum offers unique advantages for glass melting operations:
- Great machinability.
- Resistance to corrosion.
- Minimizes detrimental glass discoloring.
- High thermal and electrical conductivity.
- Low coefficient of thermal expansion (CTE).
- Excellent strength and stability at temperatures over 2000°C.
- Advanced electrical, mechanical, thermal and non-corrosive properties.
glass melting electrodes: key features
The key features of our electrodes and glass melting solutions includes:
- Ultra high purity (99.95% minimum).
- Bubble-free, low carbon electrodes.
- Available with standard or tapered threads.
- Molybdenum and MoZrO2 (coated or uncoated).
- Standard diameters from 1.25 in (32 mm) to 8 in (203 mm).
- Wide range of sizes for various glass chemistries and furnace designs.
- Machined or centerless ground surfaces (for concentricity and straightness).
Oxidation-protective coatings for Aggressive Glass Melts
We are continually improving our coatings to provide molybdenum and other refractory metals with outstanding protection against oxidation at high temperatures. Reliable and reproducible, these coatings protect against oxidation from air, oxygen-rich atmospheres, oxidizing chemicals and flames. It is fully compatible with molybdenum and can be used with other glass industry components.
High-Purity Molybdenum
(Mo) Electrodes
Elmet Technologies offers high-purity Molybdenum (Mo) electrodes, capable of exceeding the electrical, mechanical, process, corrosion, and cost requirements of the glass melting process. Molybdenum is the de facto material of choice for glass melting, due to its many outstanding properties.
Premium Molybdenum-Zirconium
(MoZrO₂) Electrodes
Elmet Technologies also manufactures a full line of premium Molybdenum-Zirconium (MoZrO₂) glass melting electrodes. These premium electrodes are manufactured from a unique molybdenum alloy material, doped with Zirconium Oxide (ZrO₂), made for advanced glass melting applications.
