Compare E-beam models, capacity-based crucibles and cylindrical size ranges. Specify OD, ID, height, wall thickness, lid requirements, quantity and operating conditions for a drawing-based review.
Catalog model: send the ECMO or MoC code and quantity. Custom crucible: send OD, ID, height, wall and base thickness, lid/spout requirements, material purity or grade, quantity and a drawing.
Include charge material, peak temperature, dwell, vacuum or gas conditions, heating/cooling cycle, supports, cleanliness and inspection requirements. Original sintered/forged size envelopes and cylindrical size bands describe different configurations; confirm the selected dimensions.
| Construction / route | What to confirm |
|---|---|
| Machined from forged or worked stock | Grade, stock condition, grain orientation, wall/base transitions and drawing |
| Pressed and sintered | Selected density, porosity, surface condition and acceptance criteria |
| Spin-formed or welded construction | Starting sheet/plate state, seam design, forming limits and inspection |
| Pure Mo or TZM | Exact chemistry and condition; performance and material standards are not interchangeable |
Choose a catalog code or provide a drawing for a custom geometry. Pure molybdenum, TZM, material state and manufacturing route must be specified separately. The tables retain all existing E-beam models, capacity models and cylindrical ranges.
Material: Molybdenum (Mo)
Purity: Mo≥99.95% for the published pure-Mo option; confirm certificate.
Published density span: 9.8–10.2 g/cm³ across different material states; confirm the selected route.
Material standard scope: ASTM B387/B387M covers bar, rod and wire; ASTM B386/B386M covers flat mill products. Neither by itself specifies a finished crucible. Confirm starting form, grade, ordered edition and drawing/inspection criteria.
Size Range: Sintered Type Dia. 10~500mm * Height 10~600mm
Forged Type Dia.10~130mm * Height 10~200mm
Type: Milled Type, Spin-formed Type, Pressed and Sintered Type, Welded Type
E-beam selection: use the complete ECMO table below. For evaporation, crystal growth, sintering or metallurgical processing, review charge compatibility, oxygen exposure, contamination limits and thermal/mechanical loading; these applications are not blanket corrosion-resistance or service-life guarantees.

The existing catalog distinguishes sintered and forged/machined material. Published densities are 9.8–10.0 g/cm³ for the sintered description and up to 10.2 g/cm³ for the forged description; confirm the density and material state for the selected design.
The previous 1,100–1,700°C application range is conditional on atmosphere, charge, loading and thermal cycle. It is not a common operating rating for all products. Hot molybdenum is susceptible to oxidation; specify vacuum or the exact protective atmosphere, pressure and residual gases for review.
The Mo-1 powder designation in the original description does not establish an automatic equivalence to an ASTM grade. Confirm grade, purity basis, manufacturing route and inspection requirements on the quotation.

Molybdenum Crucibles and Molybdenum Boats are crucial in various high-temperature applications, especially in thin film deposition and evaporation processes.
Molybdenum boats may use pure Mo or a specified alloy and may involve cutting, folding, riveting or welding of suitable sheet/plate. Confirm the grade, material state, seam design and process route against the drawing; these operations are not interchangeable.
For evaporation or furnace use, specify the charge, support, atmosphere, temperature cycle and cleanliness requirements. Review oxidation and reaction risks for each application. View Molybdenum Boats.
Molybdenum Crucibles and Boats are crucial in various high-temperature applications, especially thin film deposition and evaporation.
Here are some critical points about Molybdenum Crucibles and Boats for evaporation:
Select the material, construction and inspection scope for the actual process. No universal lifetime, thermal-shock resistance or operating-temperature rating is implied by these catalog options.
Parts are tagged and labeled for identification, with protective packaging intended to reduce handling and transport damage. Specify any additional cleanliness, inspection record or packaging requirement in the inquiry.
