This tungsten evaporation wire requires a water-cooled e-beam hearth or tungsten/tantalum support for evaporation. Compatibility with the deposition source geometry and process route must be confirmed before use.
- Evaporation Method Compatibility: E-beam evaporation is preferred; thermal evaporation is only suitable for thin charges under qualified setup.
- Source Material Requirement: The evaporation source must be a water-cooled e-beam hearth or a tungsten/tantalum support configured per RFQ.
- Melting Point Constraint: The high melting point of 3410°C necessitates robust source materials and thermal management.
- Z-Ratio Calibration: The Z-ratio of 0.163 must be used for accurate deposition rate monitoring in quartz crystal microbalance systems.
- Infrastructure Requirement: Vacuum deposition equipment with appropriate source geometry and power supply is required.
Why is e-beam evaporation recommended over thermal evaporation for this tungsten wire (99.99%, 0.5 mm diameter)?
E-beam evaporation is preferred because tungsten's high melting point (3,410°C) and density (19.35 g/cm³) require localized heating; thermal evaporation is only suitable for thin charges or qualified setups. The Z-ratio of 0.163 also indicates the need for accurate rate monitoring typical of e-beam systems.
What deposition source configurations are compatible with this tungsten evaporation material?
The tungsten wire is compatible with water-cooled e-beam hearths or tungsten/tantalum (W/Ta) support by RFQ. Buyers must confirm deposition source geometry, required quantity, and evaporation method before ordering.
What procurement and handling checks are required before ordering this tungsten wire?
Buyers must confirm model, purity (99.99%), form (wire), size (0.5 mm dia), pack size (100g, 500g, or 1kg), and deposition-source compatibility. Documentation review including certificate, safety data sheet, and shipment conditions should be matched to laboratory use requirements.
Tungsten wire (99.99%, 0.5 mm dia.) is a high-purity evaporation material optimized for e-beam deposition, requiring water-cooled hearth or specialized support due to its high melting point (3,410°C) and density (19.35 g/cm³).
Positive
- High purity and defined wire form: 99.99% purity and 0.5 mm wire diameter enable consistent deposition behavior in e-beam evaporation systems, reducing batch-to-batch variability.
- Specified Z-ratio and density: Explicit Z-ratio (0.163) and density (19.35 g/cm³) allow accurate process parameter calculation for quartz crystal microbalance thickness monitoring.
Trade-offs
- High melting point limits source compatibility: Melting point of 3,410°C requires e-beam evaporation as preferred method; thermal evaporation is only feasible for thin charges with qualified setups, restricting use with standard resistive sources.
- Specialized source infrastructure required: Optimal deposition requires a water-cooled e-beam hearth or tungsten/tantalum support by RFQ, adding procurement complexity and infrastructure overhead for typical lab setups.
