Molybdenum (Mo) Crucible | Custom High-Temperature Crucibles

Molybdenum Crucibles come in several types, including organic, sintered, spinning, stamping, and welded. They can be manufactured with or without a cover to form a set, with the addition of a customized molybdenum crucible lid.

Molybdenum Crucible and Lids Specifications

Molybdenum Crucible Manufacturing Capability & Tolerances

HM is an advanced manufacturer of Molybdenum Crucibles, specializing in high-density and ultra-pure variants. The product range includes round-mouth, taper, ellipse, and bottomless crucibles, all customizable to meet customer specifications and drawings.

Tighter tolerances may be available depending on crucible size, wall thickness, material grade, fabrication route, and quantity. Please provide a drawing for precision-machined crucibles.

Molybdenum Crucible Production Method

The molybdenum crucible is sintered or forged from the high-purity molybdenum powder.

•   Hot pressing --> sintering --> tooling.    Density, 9.8-10.0g/cc
•   Hot pressing --> sintering --> forging --> tooling.   Density up to10.2g/cc
•   Sheets --> deep drawing --> tooling.

Molybdenum Crucible Application

• Sapphire Crystal Growth

  Molybdenum crucibles are used in selected sapphire single-crystal growth furnace systems where high-temperature strength and refractory-metal compatibility are required.

  Quartz & Glass Processing

  Molybdenum crucibles can be used in selected quartz and glass processing systems under suitable furnace atmospheres and operating conditions.

  Rare-Earth & Metallurgical Processing

  Molybdenum crucibles are used in selected rare-earth, metallurgical, and high-temperature materials-processing operations where material compatibility has been confirmed.

  Artificial Crystal Growth

  Custom molybdenum crucibles can be manufactured for selected artificial-crystal growth processes according to furnace geometry and thermal-cycle requirements.

  Solar & Advanced Materials

  Molybdenum crucibles may be used in selected advanced-material and solar-related manufacturing processes requiring high-temperature refractory-metal components.

  Research & High-Temperature Processing

  Custom crucibles are available for laboratories, vacuum furnaces, sintering systems, materials research, and specialty high-temperature processing.

  Material	Key Characteristics	Typical Selection
  Pure Mo	High purity, good thermal conductivity, low thermal expansion	General vacuum and high-temperature crucibles
  TZM	Higher elevated-temperature mechanical strength than pure Mo	High-load, high-temperature or mechanically demanding crucibles
  MoLa	Improved high-temperature structural stability compared with pure Mo	Thermal-processing and furnace applications

FAQ

What molybdenum crucible materials are available?

Heeger Materials supplies pure molybdenum, TZM, and MoLa crucibles. Material selection depends on operating temperature, atmosphere, mechanical load, thermal cycling, and process compatibility.

What sizes are available?

Standard manufacturing capability currently includes crucibles from approximately 10–500 mm outer diameter and 10–600 mm height, with custom dimensions available depending on manufacturing route.

What purity is available?

Pure molybdenum crucibles are currently listed in 99.95% and 99.99% purity options.

Can you manufacture custom wall thickness and bottom thickness?

Yes. Wall thickness, bottom thickness, OD, ID, height, and dimensional tolerances can be customized according to drawing and manufacturing feasibility.

Molybdenum Crucible Packing

Molybdenum Crucible will be carefully packaged in wooden cases, supported with soft materials to prevent any movement during transportation. This ensures that the products remain securely in place throughout the packaging process.
