Niobium pellets require high-temperature e-beam evaporation with a Z-ratio of 0.492 for accurate thickness monitoring. The material must be used with compatible liner materials such as graphite, Al2O3, BN, or Ta to prevent chemical reaction or melting point failure.
- Evaporation Source Compatibility: Use only water-cooled copper e-beam hearths with compatible liners to avoid thermal damage or contamination.
- Melting Point Consideration: The high melting point of 2,468°C necessitates sustained e-beam power and appropriate hearth cooling.
- Z-Ratio Calibration: The Z-ratio of 0.492 must be entered into the deposition controller to ensure correct film thickness measurement.
- Purity Verification: Confirm the 99.99% purity specification to avoid introducing contaminants into the thin film.
What is the recommended evaporation method and hearth liner compatibility for Niobium pellets with a melting point of 2,468 °C?
E-beam evaporation is preferred due to niobium's high melting point of 2,468 °C. The compatible evaporation source is a water-cooled copper e-beam hearth, with graphite, Al2O3, BN, or Ta liners as compatible options. This configuration ensures thermal management and prevents contamination during deposition.
Does the 3-6 mm pellet size of this 99.99% pure niobium evaporation material impose any constraints on source loading or deposition rate control?
The 3-6 mm pellet size is specified to support source loading and evaporation review, but buyers must confirm deposition source geometry before ordering. The size range is typical for e-beam hearths, but compatibility with specific crucible or liner dimensions should be verified to ensure uniform melt and stable deposition rates.
What handling or storage considerations are required for niobium pellets with a density of 8.57 g/cm³ and a Z-ratio of 0.492?
Niobium pellets have a density of 8.57 g/cm³, which influences handling weight and packing density. The Z-ratio of 0.492 is relevant for quartz crystal microbalance (QCM) thickness monitoring calibration during e-beam evaporation. Storage should follow standard practices for reactive metals to avoid surface oxidation, though the source does not specify inert atmosphere requirements.
Niobium (Nb) evaporation pellets at 99.99% purity with 3-6 mm pellet size for e-beam deposition; high melting point (2468°C) requires water-cooled copper hearth and compatible liner, and the material's density and Z-ratio inform process parameter tuning.
Positive
- High purity grade: 99.99% purity minimizes film contamination for consistent thin-film properties in research-grade deposition.
- Defined pellet size range: 3-6 mm pellets facilitate uniform source loading and stable evaporation rate control in e-beam systems.
Trade-offs
- Requires e-beam evaporation hardware: Melting point of 2468°C necessitates water-cooled copper e-beam hearth and compatible liners (graphite, Al2O3, BN, Ta), limiting use to e-beam systems with appropriate infrastructure.
- Process parameter sensitivity: Material density (8.57 g/cm³) and Z-ratio (0.492) must be matched to deposition source geometry and process control, requiring careful calibration for film thickness uniformity.
