Molybdenum Crucibles – High-Temperature Metal Crucibles for Furnaces & Crystal Growth
M-Kube Enterprise supplies high-purity molybdenum crucibles designed for ultra-high-temperature applications in vacuum and inert gas atmospheres. Known for their excellent thermal conductivity, mechanical strength, and a high melting point of 2622°C, these crucibles are essential in crystal growth, semiconductor processing, and metal refining across USA laboratories and industrial facilities.
Molybdenum crucibles are compatible with many chemical environments at room temperature—resistant to hydrochloric acid, hydrofluoric acid, and alkalis—but reactive to nitric acid, sulfuric acid, and aqua regia. Above 400°C in oxidizing atmospheres, molybdenum begins to oxidize and vaporize. For operations at ~2000°C, always use in a vacuum or inert environment.
Custom Molybdenum Crucibles Engineered for Precision and High Heat
M-Kube Enterprise provides both standard and custom Mo crucibles to suit specific temperature ranges, process atmospheres, and dimensional tolerances. Whether you’re working on sapphire crystal growth or metal alloy melting, our molybdenum crucibles can be tailored to your setup.
Customization application options include:
- Cylindrical, conical, stepped designs
- Thin-wall or thick-wall construction
- Welded or seamless manufacturing
- Precision machining for vacuum chamber integration
- Coated crucibles with ZrO₂ or BN lining
- Surface finishing based on process chemistry
Our U.S. clients rely on us for quick-turn prototypes and bulk production support.
Thermal and Mechanical Properties of Molybdenum Crucibles
Molybdenum is a refractory metal ideal for extreme environments. Its properties include:
- Melting point: 2622°C, Boiling point: 4639°C
- Low thermal expansion and excellent dimensional stability
- High thermal and electrical conductivity
- Exceptional strength-to-weight ratio
- Corrosion resistance in vacuum and inert gas
- Excellent machinability and structural integrity
These features make molybdenum crucibles critical in high-temp crystal growth, metal evaporation, and vacuum sintering applications.

Product FAQ's
Refractory metal molybdenum crucibles (or Mo crucibles) can handle up to 2,900 °C in vacuum and about 1,900 °C in inert gas. These temperature limits make molybdenum crucibles ideal for extreme applications like crystal growth and vacuum evaporation.
No. While Mo crucibles resist many molten metals and non-oxidizing melts, they oxidize rapidly above 600 °C in air. For processes involving oxygen or reactive gases, use an inert-gas shield or vacuum environment to protect the crucible.
Molybdenum crucibles are widely used in:
-Vacuum and inert-gas furnace work
-Sapphire and rare-earth crystal growth (often alongside MoSi₂ heating elements)
-Semiconductor manufacturing
-High-temperature sintering
Their compatibility with MoSi₂ heating elements ensures consistent temperature control in demanding industrial settings.
Typical geometries include:
-Cylindrical molybdenum crucibles (standard beaker style)
-Molybdenum boat crucibles (flat-bottom for uniform heating)
-Molybdenum crucibles with lids (for enclosed processes)
Diameters range from a few millimeters in lab models to large industrial sizes. Custom dimensions are also available.
Yes. Leading molybdenum crucible suppliers in USA and molybdenum suppliers offer tailor-made Mo crucibles—adjusting wall thickness, shape, surface finish, and adding features like lids or handles to your specifications.
