Description
Molybdenum Lanthanum Alloy Plate – MoLa Sheet
✨ Introduction
Molybdenum Lanthanum Alloy Plate is a high-performance refractory alloy plate made by doping molybdenum with a small percentage of lanthanum oxide (La₂O₃). Commonly referred to as Mo-La Alloy Plate or Lanthanated Molybdenum Plate, this advanced material is designed to overcome the limitations of pure molybdenum by enhancing its high-temperature ductility, creep resistance, and structural stability.
With its superior characteristics, the Molybdenum Lanthanum Alloy Plate has become a preferred choice in applications such as high-temperature furnaces, semiconductor production, aerospace technology, and vacuum thermal equipment.
For this Molybdenum Lanthanum Alloy Plate, specify the lanthana addition, material condition and finished-product acceptance requirements in the order. Use the ASTM B386/B386M flat-product scope as a reference when agreeing the applicable specification, and state the required MoLa composition and analysis in the purchase requirements.
🔬 Composition and Material Characteristics
-
Base Material Reference: Molybdenum (Mo ≥ 99.95%); confirm base purity and finished MoLa chemistry on their stated analysis bases
-
Alloying Addition: Lanthanum Oxide (La₂O₃, typically 0.3–1.2 wt%); confirm the ordered oxide addition and state whether the analysis reports La₂O₃ or elemental La
-
Density: ~10.2 g/cm³
-
Melting Point: ~2620 °C
-
Microstructure: Fine-grained structure stabilized by La₂O₃ dispersoids
The technical data list a combined Mo + La₂O₃ purity figure. Specify the required elemental analysis, oxide addition and acceptance criteria for the finished plate.
✔ The addition of lanthanum oxide particles significantly inhibits grain growth at elevated temperatures.
✔ The dispersed La₂O₃ strengthens the molybdenum matrix, improving ductility and creep resistance.
⚙️ Key Benefits
1️⃣ Superior High-Temperature Strength
The Molybdenum Lanthanum Alloy Plate maintains excellent mechanical strength at temperatures above 1500 °C, outperforming pure molybdenum.
2️⃣ Excellent Thermal Stability
Unlike conventional molybdenum, Mo-La Alloy Plate resists recrystallization and grain coarsening, ensuring long-term stability.
3️⃣ Improved Ductility and Toughness
The lanthanated microstructure provides enhanced ductility, preventing brittle fracture during thermal cycling.
4️⃣ Creep Resistance
Lanthanated Molybdenum Plate exhibits low creep rates, making it reliable for prolonged service in vacuum furnaces and aerospace components.
5️⃣ Low Vapor Pressure
At elevated temperatures, Molybdenum Lanthanum Oxide Plate demonstrates low vapor pressure, avoiding contamination in vacuum and semiconductor processes.
🔍 Comparison with Other Molybdenum Alloys
| Alloy Type | Composition | Key Properties | Applications |
|---|---|---|---|
| Pure Molybdenum | Mo ≥ 99.95% | High melting point, but brittle at high temp | Standard furnace parts |
| TZM Alloy | Mo + Ti + Zr + C | High strength, creep resistant, less ductile | Rocket nozzles, die casting |
| Mo-La Alloy Plate | Mo + La₂O₃ | Enhanced ductility, thermal stability, anti-creep | Semiconductor, aerospace, furnaces |
📌 The Mo-La Alloy Plate bridges the gap between ductile performance and high-temperature resistance, making it more versatile than TZM or pure molybdenum.
