This material requires e-beam evaporation in a water-cooled copper hearth or compatible liner. The melting point and Z-ratio must be accounted for during deposition rate calibration and process parameter selection.
- Evaporation Source Compatibility: Use only in e-beam evaporation systems with a water-cooled copper hearth or graphite, Al2O3, BN, or Ta liners.
- Thermal and Deposition Constraints: The melting point of 1,966 °C and Z-ratio of 0.21 influence deposition rate calibration and process parameter selection.
- Application Matching Requirement: Match the deposition source hardware and process route to the material's melting point, behavior, and film requirements.
- Physical Form Handling: Confirm the 1–3 mm piece size is compatible with the e-beam hearth geometry before loading.
What is the significance of the Z-ratio of 0.21 for Rhodium evaporation material in e-beam deposition?
The Z-ratio of 0.21 indicates the acoustic impedance mismatch between Rhodium and the quartz crystal sensor used for film thickness monitoring during e-beam evaporation. This value must be entered into the deposition controller to ensure accurate thickness measurement and process control, as specified for this product.
Which liner materials are compatible with Rhodium evaporation at its melting point of 1966°C?
Compatible liner materials for Rhodium evaporation include graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum), as stated in the product specifications. These materials can withstand the high melting point of 1966°C and are suitable for use with a water-cooled copper e-beam hearth.
How does the piece size of 1–3 mm affect loading and evaporation behavior in e-beam systems?
The 1–3 mm piece size is designed to facilitate consistent loading into e-beam hearths and ensure uniform melting and evaporation rates. Smaller pieces allow for better packing density and thermal contact, which is critical for stable deposition rates, as specified for this product.
Rhodium (Rh) evaporation material at 99.99% purity in 1-3 mm pieces is optimized for e-beam evaporation with water-cooled copper hearths, offering high melting point (1,966°C) and density (12.4 g/cm³) that require careful source matching and rate calibration.
Positive
- High Purity (99.99%): Ensures minimal contamination for sensitive thin-film deposition in research and advanced coating applications.
- Defined Piece Size (1-3 mm): Facilitates consistent source loading and stable evaporation rate in e-beam systems.
Trade-offs
- High Melting Point (1,966°C): Requires high-temperature e-beam evaporation capability and compatible liner materials such as graphite, Al2O3, BN, or Ta to avoid reaction.
- High Density and Z-Ratio (0.21): Density of 12.4 g/cm³ and Z-ratio of 0.21 may necessitate recalibration of quartz crystal microbalance (QCM) film thickness monitors for accurate deposition rate control.
