This iridium evaporation material requires e-beam evaporation as the preferred method to achieve controlled vaporization. Its high melting point and density demand careful source matching and power control to avoid contamination or incomplete melting.
- Evaporation Method Constraint: E-beam evaporation is the preferred method; thermal evaporation is only applicable for thin charges under a qualified setup.
- Source Compatibility Constraint: The evaporation source must be a water-cooled e-beam hearth or a tungsten or tantalum support, as specified by RFQ.
- Material Property Constraint: The high melting point of 2410°C and density of 22.42 g/cm³ require careful matching of source power and deposition parameters.
- Process Matching Constraint: Deposition source hardware and process parameters must be matched to the material's melting point and film requirements to ensure repeatable quality.
Why is e-beam evaporation recommended over thermal evaporation for Iridium wire (99.95%, 0.5 mm dia.)?
E-beam evaporation is recommended per product specifications due to iridium’s high melting point (2,410) and density (22.42), which make thermal evaporation feasible only under specific conditions such as thin charges or qualified setups using water-cooled e-beam hearth or W/Ta support by RFQ.
What evaporation source hardware is compatible with Iridium wire?
The compatible evaporation source includes a water-cooled e-beam hearth or tungsten/tantalum (W/Ta) support by request for quotation (RFQ), as specified in the product details.
What is the significance of the Z-Ratio value of 0.129 specified for this Iridium evaporation material?
The Z-Ratio value of 0.129 specified for this material is used in quartz crystal microbalance (QCM) thickness monitoring during deposition to correct acoustic impedance mismatch between iridium and the quartz sensor.
Atomfair AF-IRWIR-99950P5MM-VAR Iridium evaporation wire (99.95%, 0.5 mm diameter) is a research-grade material optimized for e-beam deposition in water-cooled hearths, with a high melting point of 2,410°C and Z-ratio of 0.129 for accurate thickness monitoring. Available in 1g to 100g packs, it requires careful source matching and is not suitable for general thermal evaporation without qualified setup.
Positive
- High-purity wire form for controlled deposition: Supplied as 99.95% pure Iridium wire with 0.5 mm diameter, enabling precise loading and consistent evaporation rates in e-beam systems.
- Z-ratio provided for process monitoring: The specified Z-ratio of 0.129 allows accurate deposition rate and thickness control using quartz crystal microbalance sensors.
Trade-offs
- High melting point limits evaporation methods: With a melting point of 2,410°C, this material requires water-cooled e-beam hearths or refractory metal supports; thermal evaporation is only possible for thin charges under qualified conditions.
- Pre-order verification of source compatibility: Buyers must confirm deposition source geometry, pack size, and certificate requirements before quotation, adding procurement lead time and requiring technical coordination.
