This platinum pellet evaporation material requires a vacuum deposition system with a compatible source, either a Mo/W/Ta boat for thermal evaporation or a water-cooled e-beam hearth with graphite/alumina liner. The material's melting point of 1,772 °C and Z-ratio of 0.245 must be considered when setting evaporation parameters to ensure film uniformity and avoid source damage.
- Source Compatibility: Use only a Mo/W/Ta boat for thermal evaporation or a water-cooled e-beam hearth with graphite/alumina liner for e-beam evaporation.
- Process Parameter Matching: Calibrate deposition rate and power settings based on the material's melting point (1,772 °C) and Z-ratio (0.245).
What evaporation methods are compatible with Platinum pellets (99.999%, pellets 1–3 mm)?
The Platinum pellets are compatible with both thermal/resistive evaporation using Mo/W/Ta boat and e-beam evaporation using water-cooled e-beam hearth with graphite/alumina liner as specified in the product description.
Which crucible or boat materials are recommended for evaporating Platinum pellets at high temperature?
For thermal/resistive evaporation of Pt pellets (99.999%), Mo/W/Ta boats are specified; for e-beam evaporation use a water-cooled copper hearth with graphite or alumina liner to withstand the high temperature and prevent contamination.
What is the Z-Ratio of Platinum and why does it matter for quartz crystal thickness monitoring?
The Z-Ratio of Platinum is listed as 0.245; this value must be programmed into quartz crystal monitors during deposition to correct for acoustic impedance mismatch between Pt and quartz; using an incorrect Z-Ratio leads to systematic thickness errors in deposited films.
Platinum (Pt) evaporation pellets at 99.999% purity, 1–3 mm size, are suited for high-vacuum thermal or e-beam deposition but require careful matching of source hardware (boat material, hearth liner) and process temperature (melting point 1,772°C) to avoid contamination or equipment incompatibility.
Positive
- Ultra-high purity 99.999%: The 5N purity level minimizes contamination in thin-film deposition, critical for applications requiring high electrical conductivity or catalytic performance.
- Optimized pellet form and size: Pellets in the 1–3 mm range facilitate uniform loading into thermal boats or e-beam hearths, reducing void formation and improving evaporation consistency.
Trade-offs
- Deposition-source compatibility required: The user must confirm that the evaporation source (Mo/W/Ta boat or water-cooled e-beam hearth with graphite/alumina liner) matches the material's melting point and reactivity, or risk equipment damage or film contamination.
- High melting point imposes process limits: With a melting point of 1,772°C, evaporation requires high-temperature capability in the source, which may necessitate specialized liners and pre-qualification of thermal profiles.
