This pure metal evaporation material requires compatibility verification with deposition source hardware and process parameters. The material's high melting point (2468°C) and specific Z-ratio (0.492) necessitate precise e-beam evaporation control and matching liner selection.
- Source Compatibility: Evaporation source must use a water-cooled copper e-beam hearth with compatible liner materials such as graphite, Al2O3, BN, or Ta.
- Process Matching: Deposition parameters must be matched to material behavior, including melting point and film requirements.
- Size and Geometry: The piece size of 3-6 mm must be compatible with the source loading geometry to ensure uniform evaporation.
- Power Control: Stable e-beam power control is required to accommodate the high melting point and prevent material spitting or degradation.
Why is niobium evaporation material supplied as 3-6 mm pieces rather than powder or larger lumps for e-beam evaporation?
The 3–6 mm piece size is engineered for controlled evaporation in e-beam systems, providing an optimal balance between surface area for uniform deposition and reduced spitting compared to finer powders. This form factor is compatible with water-cooled copper e-beam hearths and liners such as graphite, Al2O3, BN, or Ta, as specified in the product description.
Can niobium evaporation material be used directly in standard e-beam evaporators without additional liner modifications?
Yes, the material is intended for e-beam evaporation and works with standard water-cooled copper e-beam hearths; recommended liner materials include graphite, Al2O3, BN, or Ta. However, due to niobium's high melting point of 2,468 °C and Z-ratio of 0.492, users must confirm deposition source geometry and liner compatibility to achieve stable deposition rates and avoid thermal mismatch.
What storage and handling considerations are required for niobium evaporation pieces to prevent contamination or oxidation before deposition?
Niobium pieces of 99.95% purity should be stored in a dry, inert environment to minimize surface oxide formation. The 3–6 mm piece form factor facilitates handling without dust hazards, but direct skin contact should be avoided. Users are advised to consult the safety data sheet and review shipment conditions to ensure material integrity prior to use.
Niobium (Nb) evaporation material in pieces (3–6 mm) at 99.95% purity is specified for e-beam deposition with compatible water-cooled copper hearth and graphite/Al2O3/BN/Ta liners. The high melting point (2,468°C) and density (8.57 g/cm³) require matching source hardware and process parameters for reliable thin-film fabrication.
Positive
- Defined high purity and form: Niobium pieces at 99.95% purity with 3–6 mm sizing ensure consistent material identity and loading compatibility for vacuum deposition workflows.
- Compatible with e-beam evaporation: Explicitly recommended for e-beam evaporation using water-cooled copper hearth and compatible liners (graphite, Al2O3, BN, Ta), facilitating integration into standard evaporation systems.
Trade-offs
- Requires specific deposition hardware: Optimal performance depends on water-cooled copper e-beam hearth and compatible liner materials; alternative source configurations may not be suitable without additional verification.
- High melting point demands process control: With a melting point of 2,468°C and density of 8.57 g/cm³, users must carefully match evaporation source power and ramping protocols to avoid material spitting or incomplete evaporation.
