This material requires vacuum thin-film deposition using thermal or e-beam evaporation. Process parameters must account for the material's melting point of 1554°C, density of 12.02 g/cm³, and Z-ratio of 0.357 for accurate rate monitoring.
- Evaporation Source Compatibility: Use only Mo/W/Ta boats or water-cooled e-beam hearths with graphite or alumina liners to avoid contamination and ensure proper wetting.
- Vacuum Process Requirement: All deposition must occur in a high-vacuum environment to prevent oxidation and achieve desired film purity.
- Pellet Size Constraint: The 3–6 mm pellet size must be confirmed to match the source crucible or boat dimensions for consistent feeding and evaporation rate.
What boat materials are compatible with thermal evaporation of palladium pellets?
For thermal/resistive evaporation of palladium pellets (99.95%, 3–6 mm), molybdenum (Mo), tungsten (W), or tantalum (Ta) boats are recommended as stated in the product specifications. For e-beam evaporation, a water-cooled e-beam hearth with graphite or alumina liner should be used.
Why is the Z‑ratio of palladium (0.357) important for thin film deposition?
The Z‑ratio of palladium is listed as 0.357 in the technical specifications. This value is critical for calibrating quartz crystal microbalance (QCM) thickness monitors during evaporation; an incorrect Z‑ratio leads to inaccurate film thickness measurements.
How does the pellet size range (3–6 mm) influence evaporation source loading?
The palladium pellets are supplied in a 3–6 mm size range specifically to facilitate consistent loading into thermal boats (Mo/W/Ta) or e‑beam hearth liners (graphite/alumina). This size ensures proper contact and uniform melting during evaporation without bridging or spitting issues common with larger chunks.
Palladium (Pd) pellets, 99.95% purity, 3-6 mm, offer a defined form factor for vacuum deposition. The material requires careful source matching and high-temperature equipment, but provides consistent film quality for research applications.
Positive
- High purity 99.95%: The 99.95% purity specification minimizes impurity-induced defects in thin films, making it suitable for sensitive electronic and catalytic applications.
- Defined pellet size 3-6 mm: The 3-6 mm pellet dimensions facilitate consistent loading into thermal or e-beam evaporation sources, promoting uniform evaporation rates.
Trade-offs
- Deposition source compatibility required: This material requires careful matching to Mo/W/Ta boats or water-cooled e-beam hearths with graphite/alumina liners; incorrect source selection may cause contamination or equipment damage.
- High melting point 1554°C: The 1554°C melting point necessitates high-power thermal or e-beam evaporation systems, limiting compatibility with low-temperature deposition setups.
