Introduction: The Strategic Role of Molybdenum Plate in Industrial Evolution
Molybdenum plate, a high-performance metal material with a melting point of 2,620°C and exceptional thermal conductivity, has become indispensable in extreme environments. From traditional steel production to cutting-edge semiconductor manufacturing, this material’s applications are expanding rapidly. This article systematically explores its utilization across industries, integrating technical parameters and real-world case studies to reveal its transformative potential.
Section 1: Traditional Industrial Foundations
1.1 Aerospace Engineering: Defying Extreme Conditions
Molybdenum plate’s high-temperature stability (up to 2,900°C in vacuum) makes it critical for aerospace components. For instance, TZM alloy plates (titanium-zirconium-molybdenum) are used in rocket nozzle liners and combustion chambers, where they withstand thermal shocks exceeding 1,500°C. The material’s low thermal expansion coefficient (5.1×10⁻⁶/K) ensures dimensional accuracy during rapid temperature fluctuations, a key requirement for reusable spacecraft.

1.2 Nuclear Energy: Radiation-Resistant Infrastructure
In nuclear reactors, molybdenum plates serve dual roles:
- Structural Components: Pure molybdenum plates (≥99.95% purity) form shielding structures due to their neutron absorption cross-section of 2.6 barns.
- Fuel Cladding: Molybdenum-lanthanum (MoLa) alloy plates, with recrystallization temperatures raised to 1,600°C, are being tested as alternative cladding materials to reduce hydrogen embrittlement risks.
A 2025 case study by China National Nuclear Corporation demonstrated that MoLa plates maintained mechanical integrity after 5,000 hours of exposure to 600°C steam environments.

1.3 Chemical Processing: Corrosion-Resistant Vessels
Molybdenum’s resistance to hydrochloric acid (HCl) concentrations up to 30% at 100°C makes it ideal for chemical reactors. For example, Jiangxi Copper Corporation uses 25mm-thick molybdenum plates to fabricate electrolytic cells for copper refining, extending equipment lifespan by 300% compared to stainless steel alternatives.

- ALD Compatibility: Lam Research’s ALTUS® Halo system enables precise Mo deposition through solid-state precursors, achieving 50% lower wordline resistance in 3D NAND flash memory.
Micron Technology’s 2025 production data shows that Mo-based interconnects improved DRAM chip yields by 8% while reducing power consumption by 12%.
