This tungsten wire evaporation material requires an e-beam evaporation source for standard deposition, with thermal evaporation only suitable for thin charges or qualified setups. The material must be used with a water-cooled e-beam hearth or a tungsten/tantalum support, and its high melting point (3410°C) necessitates careful power management to avoid crucible damage.
- Evaporation Method Constraint: E-beam evaporation is the preferred method, while thermal evaporation is only acceptable for thin charges or qualified setups.
- Source Compatibility Constraint: The material must be loaded into a water-cooled e-beam hearth or a tungsten/tantalum support, as specified by RFQ.
- Melting Point Constraint: The high melting point of 3410°C requires high-power e-beam sources and careful thermal management to prevent crucible damage.
- Z-Ratio Monitoring Constraint: The Z-ratio of 0.163 must be considered for accurate film thickness monitoring during deposition.
Why is e-beam evaporation preferred over thermal evaporation for this tungsten wire with a melting point of 3,410°C?
E-beam evaporation is preferred because tungsten's extremely high melting point (3,410°C) and Z-ratio of 0.163 require concentrated, localized heating to vaporize the material without damaging the crucible. Thermal evaporation is only recommended for thin charges or qualified setups, as stated in the product specifications.
What hearth or support material is compatible with tungsten evaporation in an e-beam system?
The product is specified for use with a water-cooled e-beam hearth or tungsten/tantalum support materials available by RFQ. This ensures compatibility with standard deposition hardware while allowing custom configurations for specialized setups.
What documentation should be reviewed before procuring this tungsten evaporation material?
Buyers should review the certificate of analysis, safety data sheet, shipment conditions, and export requirements to confirm the material meets laboratory use standards and regulatory compliance. The product description emphasizes verifying model, purity, form, size, and deposition-source compatibility before quotation.
Tungsten wire evaporation material (99.95%, 1.0 mm dia.) delivers high-purity, high-temperature e-beam deposition capability but requires water-cooled hearth or specialized support and is not suited for routine thermal evaporation.
Positive
- High purity and defined wire form: Purity of 99.95% and wire diameter of 1.0 mm ensure consistent evaporation rate control and film stoichiometry for vacuum deposition.
- Specified thermophysical properties: Melting point (3410°C) and Z-ratio (0.163) are provided, enabling accurate process parameter calculation for e-beam deposition.
Trade-offs
- Restricted thermal evaporation compatibility: Thermal evaporation is only recommended for thin charge or qualified setups; general thermal evaporation is not advised for this material.
- Infrastructure requirement for evaporation source: Optimal use requires a water-cooled e-beam hearth or W/Ta support (by RFQ), adding equipment and setup complexity for the lab.
