High purity Molybdenum Metal Sheet&Powder Assay 99.7～99.9%
Molybdenum
Synonyms: Molybdan (German）
(Originated from molybdos of lead meaning in Greek); one kind of metal elements; element symbol: Mo; atomic number: 42; atomic weight: 95.94; silver white metal; hard; added in steel for high-speed steel manufacturing; liquid lead.
Molybdan is not used much in industries. In high-temperature industries with requirements of mechanical properties, it’s often used (such as positive electrode for vacuum tube) as it’s cheaper than tungsten. Recently, the application in panel production line such as plasma power panel has been increasing.

What is Molybdenum Sheet and Molybdenum Powder used for?
Applications of Molybdenum Sheet
Molybdenum sheet, a high-purity refractory metal product, is valued for its exceptional thermal stability, electrical conductivity, and corrosion resistance. Key uses include:
1. Electronics & Semiconductor Industry
- Electric Vacuum Components: Used in high-power electron tubes, X-ray tubes, and vacuum interrupters due to its low thermal expansion and high melting point (~2,623°C).
- Semiconductor Devices: Fabricates heat sinks, electrodes, and substrates for power semiconductor devices (e.g., thyristors, diodes) to ensure efficient heat dissipation.
- Lighting Systems: Manufactures filaments, supports, and reflectors for halogen lamps, LED modules, and high-intensity discharge (HID) lamps.
2. High-Temperature Industrial Applications
- Furnace Components: Serves as heat shields, heating elements, and crucibles in vacuum or inert-atmosphere furnaces for sintering, annealing, and crystal growth processes.
- Molybdenum Boats: Shapes into evaporation boats for thin-film deposition in coating technologies (e.g., solar panels, optical coatings).
3. Aerospace & Defense
- Rocket Nozzles: Withstands extreme temperatures and erosion in aerospace propulsion systems.
- Radiation Shielding: Used in nuclear reactors and spacecraft for its ability to block high-energy particles.
