This rhodium pellet material requires e-beam evaporation using a water-cooled copper hearth with compatible liner materials such as graphite, Al2O3, BN, or Ta. The Z-ratio of 0.21 must be entered into the deposition controller for accurate thickness monitoring.
- Evaporation Source Compatibility: Use only water-cooled copper e-beam hearth with graphite, Al2O3, BN, or Ta liners to avoid contamination and ensure proper thermal contact.
- Deposition Parameter Setup: Set deposition controller Z-ratio to 0.21 for accurate film thickness measurement during e-beam evaporation.
- Material Form Handling: Select pellets within the 3-6 mm size range to ensure consistent loading into the evaporation source.
- Purity Verification: Verify the 99.99% purity specification against the certificate of analysis to confirm suitability for the intended deposition process.
How does the Z-Ratio of rhodium (0.21) affect e-beam evaporation process control?
The Z-Ratio of rhodium is specified as 0.21 in the technical specifications for this AF-RHPEL-4N36MM material. This value is critical for quartz crystal microbalance (QCM) thickness monitoring calibration during e-beam evaporation; a lower Z-Ratio requires a higher tooling factor adjustment compared to materials with Z-Ratio near 1.0. Users must input this exact Z-Ratio into their deposition controller to achieve accurate film thickness readings.
What liner materials are recommended for evaporating rhodium pellets at its melting point of 1966°C?
For this rhodium evaporation material (melting point 1966°C), compatible liners include graphite, Al2O3 (alumina), BN (boron nitride), and Ta (tantalum), as stated in the product specifications. These materials withstand the high temperature without contaminating the melt; water-cooled copper e-beam hearths are preferred to prevent crucible reaction with molten rhodium.
Why is the pellet size range of 3–6 mm specified for this rhodium evaporation material?
The pellets are supplied in a controlled size range of 3–6 mm to ensure consistent loading into e-beam hearths and uniform evaporation behavior during deposition. This sizing prevents bridging in feed mechanisms and promotes stable melt surface area across all available pack sizes (1 g to 100 g), as noted in the product description.
Rhodium (Rh) pellets with 99.99% purity and 3–6 mm size are evaluated for e-beam evaporation deposition. The material's high melting point (1966°C) and density (12.4 g/cm³) require specific source hardware and liner compatibility, while the specified pellet form facilitates controlled loading for thin-film applications.
Positive
- High purity and controlled pellet size: The 99.99% purity and 3–6 mm pellet form enable precise material loading for consistent thin-film deposition in e-beam evaporation systems.
- High melting point and density: With a melting point of 1966°C and density of 12.4 g/cm³, the material is suitable for robust, high-performance coatings requiring thermal stability.
Trade-offs
- Requires specific e-beam source hardware: The evaporation material is designed for water-cooled copper e-beam hearths and compatible liners (graphite, Al2O3, BN, Ta); alternative sources may not be suitable.
- High melting point demands high-power system: The 1966°C melting point requires a high-power e-beam evaporation system, which may not be available in all laboratory setups and increases operational complexity.
