This iridium evaporation material is intended for electron-beam physical vapor deposition in a vacuum system. The material requires a water-cooled copper hearth and a compatible liner material such as graphite, alumina, boron nitride, or tantalum.
- Deposition Method: Electron beam evaporation is the preferred method for this material.
- Hearth Requirement: The source hearth must be water-cooled copper to dissipate heat during deposition.
- Liner Compatibility: Compatible liner materials include graphite, alumina, boron nitride, and tantalum.
- Material Properties: The material's melting point of 2,410°C, density of 22.42 g/cm³, and Z-ratio of 0.129 must be accounted for in process parameter selection.
What is the Z-Ratio of Iridium evaporation material and why is it critical for e-beam deposition?
The Z-Ratio for Iridium is specified as 0.129 in the technical specifications. This tooling factor corrects acoustic impedance mismatch between Iridium and quartz crystal sensors used in thickness monitoring during e-beam evaporation. Accurate Z-Ratio input is essential for precise film thickness control.
What crucible liner materials are compatible with e-beam evaporation of Iridium pellets?
The product description lists graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum) as compatible liner materials for use with a water-cooled copper e-beam hearth. These materials withstand Iridium's high melting point of 2,410°C without significant contamination.
What evaporation source configuration is required for depositing Iridium pellets?
E-beam evaporation using a water-cooled copper hearth with compatible liners such as graphite, Al2O3, BN, or Ta is preferred due to Iridium's high melting point of 2,410°C and density of 22.42 g/cm³. This setup ensures stable evaporation rates and prevents source damage.
This Iridium evaporation material in pellet form (99.95% purity, 3-6 mm) is suitable for e-beam deposition, but its high melting point and density impose specific hardware and process control requirements for reliable thin-film fabrication.
Positive
- High Purity 99.95% for Reliable Films: The 99.95% purity minimizes contamination in vacuum-deposited films, a critical factor for reproducible electronic, optical, or catalytic thin-film properties.
- Defined Pellet Size for Source Loading: The 3-6 mm pellet form is optimized for loading into e-beam evaporation sources, reducing risks of bridging or incomplete melting during deposition.
Trade-offs
- High Melting Point Requires Specialized Hardware: With a melting point of 2,410°C, this material demands a high-power e-beam source and water-cooled copper hearth, limiting use to systems with adequate thermal management infrastructure.
- Density and Z-Ratio Affect Process Calibration: The high density (22.42 g/cm³) and low Z-ratio (0.129) require careful calibration of deposition rate monitors and may necessitate adjusted source power ramping for stable evaporation.
