This platinum pellet material requires evaporation using a Mo/W/Ta boat or water-cooled e-beam hearth with graphite or alumina liner. The high melting point of 1,772 °C and density of 21.45 g/cm³ necessitate matching the deposition source geometry and process parameters to achieve consistent film quality.
- Evaporation Source Compatibility: The pellets must be loaded into a compatible evaporation source: either a Mo/W/Ta boat for thermal evaporation or a water-cooled e-beam hearth with graphite or alumina liner.
- Pellet Size Range: The 3-6 mm pellet size must be verified against the source crucible or boat dimensions to ensure proper loading and uniform evaporation.
- Process Monitoring Parameter: The Z-ratio of 0.245 must be entered into the deposition controller for accurate film thickness measurement during e-beam evaporation.
How does the Z-ratio of 0.245 for these platinum pellets affect the calibration of quartz crystal thickness monitors during e-beam evaporation?
The Z-ratio of 0.245 reflects the acoustic impedance of platinum relative to quartz, which must be entered into the deposition controller to correct for material stiffness and density differences. This ensures accurate film thickness measurement during e-beam evaporation. The product specification explicitly lists the Z-ratio as 0.245, enabling precise process calibration.
What evaporation source configurations are compatible with these 99.999% platinum pellets given their 3-6 mm pellet size and 1,772°C melting point?
The product is designed for thermal/resistive evaporation using Mo, W, or Ta boats, or e-beam evaporation with a water-cooled hearth using graphite or alumina liners. The pellet size of 3-6 mm is optimized for these source types, and the high melting point of 1,772°C necessitates avoiding direct contact with materials that may alloy or melt, as specified in the compatible source configurations.
What are the key procurement considerations when ordering 99.999% platinum pellets, particularly regarding pack size and documentation requirements?
The product is available in pack sizes of 1g, 5g, 10g, 25g, and 100g with indicative price tiers. Buyers should confirm the required quantity, deposition source geometry, and certificate requirements before quotation. The manufacturer recommends reviewing the certificate of analysis, safety data sheet, and shipment conditions against laboratory use requirements to ensure material suitability.
Platinum evaporation pellets with 99.999% purity and 3–6 mm size are suitable for high-vacuum thermal or e-beam deposition, requiring careful source matching and process calibration due to high melting point and density.
Positive
- High purity and defined pellet form: 99.999% purity and 3–6 mm pellet form ensure consistent evaporation behavior and minimize contamination in thin-film deposition.
- Multiple evaporation method compatibility: Compatible with thermal/resistive and e-beam evaporation using Mo/W/Ta boats or water-cooled e-beam hearths with graphite/alumina liners, providing flexibility in deposition setup.
Trade-offs
- High melting point and density: Melting point of 1,772 °C and density of 21.45 g/cm³ require high-energy evaporation sources and careful handling due to material weight.
- Z-ratio necessitates process calibration: Z-ratio of 0.245 requires thickness monitor calibration adjustments for accurate film thickness control during deposition.
