Niobium pellets require e-beam evaporation in a water-cooled copper hearth with compatible liners. Proper source matching and high-vacuum conditions are necessary to avoid contamination and achieve consistent film deposition.
- Evaporation Source Compatibility: The material must be evaporated using a water-cooled copper e-beam hearth with graphite, Al2O3, BN, or Ta liner.
- Melting Point Constraint: The high melting point of 2468 °C requires stable e-beam power control to avoid thermal shock to the hearth.
- Z-Ratio Consideration: The Z-ratio of 0.492 must be accounted for in deposition rate monitoring to ensure accurate film thickness control.
- Purity Requirement: The 99.99% purity grade requires clean handling and storage to prevent contamination of the evaporation source.
What liner materials are compatible with Niobium pellets for e-beam evaporation?
For e-beam evaporation of Niobium pellets, compatible liner materials include graphite, Al2O3, BN, and Ta. The preferred evaporation source is a water-cooled copper e-beam hearth. This compatibility information is critical for preventing contamination or hearth damage during deposition.
What is the Z-ratio of Niobium and why does it matter for thin-film deposition?
The Z-ratio of Niobium is 0.492. This value is essential for calibrating quartz crystal microbalance (QCM) thickness monitors during e-beam evaporation, as it corrects for the acoustic impedance mismatch between the deposited film and the crystal sensor, ensuring accurate film thickness control.
What pack sizes are available for the 99.99% Niobium pellets and what are the indicative price tiers?
The Niobium pellets (99.99%, 1-3 mm) are available in pack sizes of 25g, 100g, 500g, and 1kg. Indicative price tiers are USD 220 for 25g, USD 450 for 100g, USD 1150 for 500g, and USD 1550 for 1kg. Buyers should confirm required quantity and deposition source geometry before quotation.
This 99.99% pure niobium pellet evaporation material, supplied in 1–3 mm pellets, is optimized for e-beam deposition in water-cooled copper hearths with compatible liners, offering defined particle size for consistent source loading but requiring high-energy e-beam infrastructure due to its 2468°C melting point.
Positive
- High purity specification: 99.99% purity minimizes contamination in thin-film deposition, enabling reproducible film quality for research-grade applications.
- Controlled pellet size range: Pellets sized 1–3 mm facilitate uniform loading and consistent evaporation rates in e-beam hearths, reducing process variability.
Trade-offs
- Specific source hardware required: Optimal evaporation requires a water-cooled copper e-beam hearth with compatible liners (graphite, Al2O3, BN, or Ta), imposing infrastructure prerequisites.
- High melting point demands energy: With a melting point of 2468°C, the material requires high-energy e-beam sources and careful thermal management to avoid damage to adjacent components.
