This material requires careful matching to deposition source hardware and process parameters. Confirmation of model, purity, form, and pack size is necessary before procurement.
- Evaporation Source Compatibility: The material must be used with a water-cooled copper e-beam hearth or compatible graphite, Al2O3, BN, or Ta liner.
- Procurement Confirmation: Buyers must confirm model, purity, form, size range, pack size, and deposition-source compatibility before quotation.
- Documentation Review: Certificate, safety data sheet, shipment conditions, and export requirements should be reviewed against laboratory use requirements.
- Process Matching: The evaporation source hardware and process route must be matched to the material's melting point, density, and film requirements.
What is the Z-ratio of rhodium evaporation pellets and how does it affect deposition rate monitoring?
The Z-ratio for rhodium is 0.21. This parameter is critical for accurate quartz crystal microbalance (QCM) thickness monitoring; it corrects for the acoustic impedance mismatch between the crystal and the deposited film. The value must be entered into the deposition controller to ensure precise film thickness control during e-beam evaporation.
Which crucible liners are compatible with rhodium evaporation pellets?
Compatible liners include graphite, Al2O3, BN, and Ta. The preferred evaporation method is e-beam evaporation using a water-cooled copper hearth. The choice of liner depends on the specific deposition hardware, thermal conductivity requirements, and compatibility with the molten rhodium.
What is the significance of the 3-6 mm pellet size for rhodium evaporation material?
The 3-6 mm pellet size is optimized for loading into e-beam evaporation sources. It provides consistent melt characteristics, minimizes spitting, and ensures uniform evaporation. The pellets are supplied in this size range to facilitate direct use without further processing, matching standard crucible and hearth dimensions.
Rhodium (Rh) evaporation pellets (99.95%, 3-6 mm) are evaluated for e-beam evaporation requiring water-cooled copper hearth with compatible liners; high melting point (1966°C) and density (12.4 g/cm³) demand careful thermal management and process matching.
Positive
- High-purity pellets with defined size: 99.95% purity and 3-6 mm pellet form ensure consistent loading and reproducible evaporation behavior in e-beam deposition.
- Provided key process parameters: Melting point (1966°C), density (12.4 g/cm³), and Z-ratio (0.21) are specified to enable accurate process simulation and source calibration.
Trade-offs
- E-beam infrastructure requirement: Deposition requires a water-cooled copper e-beam hearth with a compatible liner (graphite, Al2O3, BN, or Ta); not suitable for alternative evaporation methods without hardware modification.
- High melting point and density constraints: The high melting point (1966°C) and density (12.4 g/cm³) demand high-power e-beam sources and careful thermal management to avoid hearth damage or process instability.
