This evaporation material requires specific source hardware and process parameters to achieve optimal film quality. Compatibility with water-cooled copper e-beam hearth and appropriate liner materials must be confirmed before use.
- Evaporation Method Compatibility: E-beam evaporation is preferred due to the material's high melting point of 1966 °C, requiring a water-cooled copper hearth or compatible liner.
- Liner Material Compatibility: Compatible liner materials include graphite, Al2O3, BN, or Ta to prevent contamination during evaporation.
- Process Control Parameters: The Z-ratio of 0.21 and density of 12.4 g/cm³ must be entered into the deposition controller for accurate rate monitoring.
- Pack Size Selection: Available pack sizes from 1 g to 100 g require confirmation of source geometry and required quantity before ordering.
- Pre-Installation Verification: Material identity, purity, form, and size range must be verified against deposition source hardware to ensure compatibility.
What is the significance of the Z-ratio (0.21) for Rhodium evaporation pellets in e-beam deposition?
The Z-ratio of 0.21 is a material-specific parameter used in quartz crystal microbalance (QCM) thickness monitoring to correct for the acoustic impedance mismatch between the deposited film and the quartz crystal. For Rhodium, this low value indicates a significant acoustic mismatch, which can affect thickness measurement accuracy if not properly calibrated. The product specification sheet provides this value to enable precise deposition rate control in e-beam evaporation systems.
Which liner material is recommended for evaporating Rhodium pellets to minimize contamination and achieve stable deposition rates?
The product specification lists graphite, Al2O3, BN, and Ta liners as compatible with the water-cooled copper e-beam hearth. For Rhodium, which has a high melting point of 1,966°C, a liner such as graphite or Ta is often preferred due to their thermal stability and low reactivity with molten Rhodium. However, the optimal choice depends on the specific deposition conditions and desired film purity; users should confirm compatibility with their hardware and process requirements before ordering.
What documentation and handling precautions are required when procuring Rhodium evaporation pellets for laboratory use?
The product includes a Certificate of Analysis and Safety Data Sheet (SDS) upon request. Rhodium is a precious metal and should be handled in a clean environment to avoid contamination. The pellets are 1-3 mm in size and should be stored in a dry, inert atmosphere to prevent oxidation. Export and shipment conditions may be subject to regulatory controls due to the material's value and classification; buyers should confirm these requirements with the supplier before ordering.
This Rhodium (Rh) evaporation material is supplied as 99.95% pure pellets in 1–3 mm size, specifically configured for e-beam evaporation using water-cooled copper hearths and compatible liners, with a melting point of 1,966°C and density of 12.4 g/cm³.
Positive
- High purity (99.95%): The 99.95% purity specification supports consistent film stoichiometry and reduces contamination risk in sensitive thin-film deposition applications.
- Optimized pellet form and size: The 1–3 mm pellet size is designed for reliable loading into e-beam evaporation sources, ensuring uniform melt and controlled deposition rates.
Trade-offs
- Specialized evaporation infrastructure: Optimal use requires a water-cooled copper e-beam hearth with compatible liners (graphite, Al2O3, BN, or Ta), limiting deployment to labs equipped with such hardware.
- High melting point and density: A melting point of 1,966°C and density of 12.4 g/cm³ demand higher electron-beam power and careful thermal management to achieve stable evaporation without source damage.
