introduce

Molybdenum-Lanthanum alloy electrode rods, commonly referred to as Mo-La rods, are high-performance materials made by doping molybdenum with a small amount of lanthanum oxide (La₂O₃). This alloy exhibits excellent mechanical strength, improved recrystallization temperature, and superior resistance to thermal deformation, making it ideal for high-temperature and vacuum applications.

Key Features:
- Composition: Typically contains 0.3–1.2 wt% La₂O₃, with the balance being molybdenum.
- High Recrystallization Temperature: Up to 1500–1600°C, significantly higher than pure molybdenum.
- Improved Creep Resistance: Excellent dimensional stability under thermal stress.
- Fine Grain Structure: Enhances machinability and surface finish quality.
Applications:
- Electrodes for high-temperature furnace environments (e.g., sapphire crystal growth, rare earth melting)
- Support rods in vacuum and inert atmosphere furnaces
- Discharge tubes and plasma arc components
- Welding electrodes and electrical contacts requiring long-term thermal stability
Advantages:
- Extended service life at elevated temperatures
- Excellent electrical and thermal conductivity
- Resistant to oxidation and contamination in inert or vacuum conditions
- Enhanced performance under cyclic thermal loads
