Niobium evaporation wire requires a water-cooled e-beam hearth or tungsten/tantalum support for deposition. E-beam evaporation is preferred; thermal evaporation is only suitable for thin charges or qualified setups due to the material's high melting point and Z-ratio.
- Evaporation Source Compatibility: The niobium wire must be loaded into a water-cooled e-beam hearth or supported by tungsten or tantalum elements for evaporation.
- Evaporation Method Restriction: E-beam evaporation is the preferred method; thermal evaporation is only permitted for thin charges or qualified setups.
- Material Behavior Consideration: The high melting point (2468°C) and Z-ratio (0.492) must be accounted for in deposition parameter planning.
- Procurement Verification: Confirm model, purity, form, size range, pack size, and deposition-source compatibility before quotation.
To procure and set up niobium evaporation material, follow these steps for specification confirmation and source matching. This ensures compatibility with deposition hardware and proper handling of documentation.
Required Equipment: Water-cooled e-beam hearth, Tungsten/tantalum support

Review the certificate, safety data sheet, shipment conditions, and export requirements against laboratory use. - Include Inquiry Details
Include the required model, purity, form, size range, and quantity when requesting quotation support.
Why is e-beam evaporation preferred over thermal evaporation for niobium wire evaporation material?
E-beam evaporation is preferred because niobium has a high melting point of 2,468°C and a low vapor pressure, making thermal evaporation feasible only for thin charges or qualified setups to avoid contamination or incomplete evaporation. The product specification explicitly states 'E-beam evaporation preferred; thermal only for thin charge/qualified setup', reflecting the practical limitations of thermal methods for this refractory metal.
What deposition source configurations are compatible with niobium wire evaporation material?
The niobium wire is compatible with water-cooled e-beam hearths or tungsten/tantalum support boats by RFQ (request for quotation). Buyers must confirm their deposition source geometry before ordering to ensure proper loading and evaporation performance, as the wire diameter of 2.0 mm and high melting point require specific hardware configurations.
What is the significance of the Z-ratio value of 0.492 for niobium evaporation material?
The Z-ratio of 0.492 is a critical parameter for calibrating quartz crystal microbalance (QCM) sensors used to monitor film thickness during vacuum deposition. It accounts for the acoustic impedance mismatch between niobium and the quartz crystal, enabling accurate real‑time thickness control and reproducible thin‑film properties.
Niobium (Nb) evaporation wire (99.95%, 2.0 mm dia.) is evaluated for vacuum thin-film deposition. The high-purity wire form is optimized for e-beam evaporation, with thermal evaporation limited to specialized setups. Buyers must verify deposition source compatibility and select appropriate pack size.
Positive
- High purity 99.95% Niobium wire: Specified material identity and purity grade of 99.95% enable clear procurement matching and process control for thin-film deposition.
- Prefers e-beam evaporation: E-beam evaporation is preferred for this wire form, leveraging its high melting point of 2,468°C for efficient deposition.
Trade-offs
- Thermal evaporation limited: Thermal evaporation is only suitable for thin charge or qualified setups; direct thermal evaporation of bulk wire may not be feasible without modification.
- Deposition source compatibility required: Buyers must confirm evaporation source geometry and hardware compatibility before ordering, as the wire form requires a water-cooled e-beam hearth or W/Ta support by RFQ.
