Tungsten wire evaporation material requires e-beam deposition with a water-cooled copper hearth or tungsten/tantalum support for thermal evaporation. The material's high melting point (3410°C) and density (19.35 g/cm³) demand precise source geometry matching and process parameter calibration.
- Evaporation Method: E-beam evaporation is preferred; thermal evaporation is only suitable for thin charges or qualified setups with water-cooled hearth or tungsten/tantalum support.
- Source Compatibility: The wire diameter of 0.5 mm must be compatible with the evaporation source geometry to ensure consistent feeding and deposition.
- Z-Ratio Calibration: The Z-ratio of 0.163 must be entered into the deposition controller for accurate thickness monitoring.
- Melting Point Consideration: The high melting point of 3410°C requires that the evaporation source can reach and sustain the necessary temperature without material degradation.
Can tungsten wire be used in thermal evaporation systems, or is e-beam evaporation mandatory?
E-beam evaporation is preferred for this tungsten wire; thermal evaporation is only acceptable for thin charges in a qualified setup. The recommended deposition source is a water-cooled e-beam hearth or W/Ta support by RFQ.
What deposition source hardware is compatible with this tungsten wire evaporation material?
The product is designed for use with a water-cooled e-beam hearth or a tungsten/tantalum (W/Ta) support by RFQ. Buyers must confirm their deposition source geometry and compatibility before ordering, as the wire form and diameter 0.5 mm affect loading and process setup.
What are the critical physical properties and handling considerations for this 99.95% purity tungsten wire?
Tungsten has a melting point of 3410°C, density of 19.35 g/cm³, and Z-ratio of 0.163. Due to its high melting point and hardness, careful handling is required, and the wire form (0.5 mm diameter) supports controlled source loading. Proper deposition hardware and safety data sheet review are recommended.
Tungsten (W) evaporation wire at 99.95% purity and 0.5 mm diameter offers high-purity material for e-beam deposition, but requires careful source geometry matching and is not universally suited for thermal evaporation without qualification.
Positive
- High purity 99.95% tungsten wire: The 99.95% purity ensures minimal contamination in thin-film deposition, critical for applications requiring consistent film stoichiometry.
- Precise wire diameter 0.5 mm: The specified 0.5 mm diameter facilitates reproducible loading into e-beam hearths and thermal crucibles, reducing variability in source-to-substrate flux.
Trade-offs
- E-beam evaporation dependency: E-beam evaporation is preferred; thermal evaporation is only suitable for thin charges with qualified setups, limiting process flexibility.
- Source geometry verification required: Compatibility with water-cooled e-beam hearth or W/Ta support must be confirmed via RFQ, requiring pre-purchase engineering assessment.
