Tungsten wire evaporation material requires a water-cooled e-beam hearth for e-beam deposition or a tungsten/tantalum support for thermal evaporation, with source geometry compatibility confirmed prior to use. The high melting point (3410°C) and Z-ratio (0.163) demand precise power control and rate monitoring to prevent film defects and source damage.
- Source Compatibility: Water-cooled e-beam hearth or W/Ta support must be used depending on evaporation method, and source geometry must be confirmed before loading.
- Thermal Management: E-beam evaporation is preferred; thermal evaporation is only suitable for thin charges or qualified setups to avoid overheating and contamination.
- Material Purity and Form: The wire diameter (2.0 mm) and 99.99% purity must be verified to match the crucible size and deposition requirements for consistent film quality.
- Process Matching: Evaporation source hardware and process route should be matched to the material's melting point and film requirements to avoid delamination or stoichiometry shifts.
- Documentation Review: Certificate, safety data sheet, and shipment conditions must be reviewed against laboratory use requirements to ensure proper handling and storage.
Confirm the wire specifications and evaporation source compatibility before loading. Execute the deposition process by matching the source hardware and process parameters to the material's properties.
Required Equipment: Water-cooled e-beam hearth, Tungsten/tantalum support (for thermal evaporation)
- Confirm Specifications
Confirm the model, purity, form, size range, and pack size match the deposition source requirements before loading. - Match Source Hardware
Match the evaporation source hardware and process route to the material's melting point and film requirements. - Review Documentation
Review the certificate, safety data sheet, and shipment conditions against laboratory use requirements.
Why is electron-beam evaporation recommended over thermal evaporation for this 99.99% tungsten wire?
E-beam evaporation is preferred for tungsten wire due to its high melting point (3,410°C), which requires concentrated heating for controlled deposition. Thermal evaporation is only suitable for thin charges or qualified setups that can handle the material's high thermal load. The water-cooled e-beam hearth is the recommended evaporation source, though W/Ta support is available by RFQ.
What deposition source hardware is compatible with this tungsten wire evaporation material?
This tungsten wire is compatible with water-cooled e-beam hearths for standard e-beam evaporation, and W/Ta support configurations can be requested via RFQ. Buyers must confirm deposition source geometry and compatibility before ordering, as the wire form (2.0 mm diameter) must fit the source loading mechanism.
What is the significance of the Z-ratio value of 0.163 for this tungsten evaporation material?
The Z-ratio of 0.163 is a critical parameter for quartz crystal microbalance (QCM) thickness monitoring during e-beam evaporation. It corrects the acoustic impedance mismatch between tungsten and the quartz crystal, ensuring accurate film thickness measurement. This value should be entered into the deposition controller for precise process control.
This tungsten wire evaporation material (99.99%, 2.0 mm diameter) is optimized for e-beam evaporation in high-temperature thin-film deposition, with constraints on thermal evaporation setup and specialized source hardware.
Positive
- High purity wire form: 99.99% purity and 2.0 mm diameter wire form ensure consistent evaporation behavior and reliable source loading for vacuum deposition.
- E-beam evaporation compatibility: Designed for water-cooled e-beam hearths, the preferred method for high-melting-point materials (3410°C), enabling efficient and controlled evaporation.
Trade-offs
- Thermal evaporation limitations: Thermal evaporation is only recommended for thin charges or qualified setups, restricting general-purpose use without source configuration validation.
- Specialized hardware required: Effective evaporation requires a water-cooled e-beam hearth or W/Ta support by RFQ, adding infrastructure and procurement complexity for standard labs.
