This niobium evaporation material must be used in a vacuum deposition system with a water-cooled copper e-beam hearth. The material is compatible with graphite, Al2O3, BN, or Ta liners and requires e-beam evaporation as the preferred method.
- Deposition Source Compatibility: A water-cooled copper e-beam hearth is required, with graphite, Al2O3, BN, or Ta liners as compatible options.
- Evaporation Method: E-beam evaporation is the preferred deposition method for this material.
- Application Matching: The material's melting point, density, and Z-ratio must be matched to the deposition source hardware and process parameters.
What is the preferred evaporation method for Niobium (Nb) pieces (99.99%, 1-3 mm) and which liner materials are compatible?
E-beam evaporation is the preferred method using a water-cooled copper e-beam hearth. Compatible liner materials include graphite, Al2O3, BN, and Ta. This configuration is specified to handle the high melting point of 2,468 °C and ensure process stability during thin-film deposition.
Does the Niobium evaporation material specification include a Z-ratio and density value for quartz crystal monitoring?
Yes, the product specification includes a Z-ratio of 0.492 and a density of 8.57 g/cm³. These values are essential for configuring the quartz crystal microbalance (QCM) sensor in the deposition controller to accurately measure film thickness during growth.
What is the minimum order quantity and available pack size range for this 99.99% Niobium evaporation material?
The minimum order quantity is 25g, with available pack sizes of 25g, 100g, 500g, and 1kg. Buyers should confirm the required quantity and deposition source geometry before quotation to ensure the 1-3 mm piece size matches the hearth or crucible dimensions.
Niobium evaporation material (99.99%, 1–3 mm pieces) delivers high-purity films via e-beam deposition but demands specific hardware and Z-ratio compensated thickness monitoring.
Positive
- High-purity niobium (99.99%): Ensures minimal contamination in thin-film deposition for applications requiring defined stoichiometry and film integrity.
- Consistent 1–3 mm piece size: Facilitates uniform source loading and stable evaporation rates in e-beam systems.
Trade-offs
- Requires e-beam evaporation hardware: The high melting point (2,468°C) necessitates electron-beam evaporation with water-cooled copper hearth and compatible liners, limiting alternative deposition methods.
- Z-ratio monitoring adjustment needed: The Z-ratio of 0.492 deviates from the commonly assumed 1.0, requiring instrument calibration for accurate quartz crystal microbalance thickness control.
