Molybdenum Shield

The molybdenum shield is a critical high-temperature component used in vacuum furnaces, controlled-atmosphere furnaces, and crystal growth furnaces. It is primarily designed for thermal radiation reflection, heat insulation, and temperature field stabilization in extreme operating environments.

Thanks to molybdenum’s high melting point (2620°C), low vapor pressure, and excellent high-temperature strength, molybdenum shields maintain stable performance where conventional metallic materials fail.

Main Functions

Thermal Radiation Shielding

Molybdenum shields reflect radiant heat back into the hot zone, helping to optimize temperature distribution and reduce unnecessary heat loss.

Thermal Insulation

As part of the furnace heat field system, molybdenum shields improve energy efficiency and contribute to more stable and uniform heating conditions.

Process Stability

By minimizing temperature fluctuations and suppressing contamination from volatile materials, molybdenum shields help ensure consistent process results and extended component service life.
