This platinum evaporation material requires specific deposition source compatibility and process parameter control. The pellet form and material properties impose constraints on boat selection, temperature management, and thickness monitoring.
- Evaporation Source Compatibility: Use a Mo/W/Ta boat for thermal evaporation or a water-cooled e-beam hearth with a graphite or alumina liner to avoid contamination and ensure uniform heating.
- Z-Ratio Calibration: The Z-ratio of 0.245 must be entered into the quartz crystal microbalance controller to achieve accurate film thickness deposition.
- Melting Point Consideration: The melting point of 1,772 °C requires a source material capable of reaching and sustaining this temperature without degrading the boat or liner.
- Pellet Loading Uniformity: Load pellets uniformly across the evaporation source to prevent localized hot spots and ensure consistent evaporation rates.
What is the significance of the Z-ratio of 0.245 for platinum pellets in e-beam evaporation thickness monitoring?
The Z-ratio of 0.245 is a material-specific parameter used in quartz crystal microbalance (QCM) thickness monitors to correct for acoustic impedance mismatch, ensuring accurate film thickness readings during e-beam evaporation. This value is provided in the product's technical specifications for the 99.99% platinum pellets.
Which crucible liner materials are compatible with platinum evaporation using a water-cooled e-beam hearth?
For e-beam evaporation of platinum, the product supports a water-cooled e-beam hearth with either graphite or alumina liner, as stated in the evaporation source specifications. These liner materials are compatible with the high melting point of platinum (1,772°C) and prevent contamination during deposition.
What are the recommended boat materials for thermal evaporation of these platinum pellets?
For thermal/resistive evaporation, the product is compatible with molybdenum (Mo), tungsten (W), or tantalum (Ta) boats, as listed in the evaporation source options. These refractory metals can withstand the melting point of platinum (1,772°C) without significant degradation, ensuring reliable evaporation.
Platinum (Pt) evaporation pellets at 99.99% purity and 1-3 mm size are suitable for thermal/resistive or e-beam evaporation using Mo/W/Ta boats or water-cooled e-beam hearths with graphite/alumina liners. The high density (21.45 g/cm³) and melting point (1,772°C) require careful source matching and process parameter optimization.
Positive
- High purity 99.99%: The 99.99% purity specification enables consistent film stoichiometry and minimizes contamination in thin-film deposition for research-grade applications.
- Pellets 1-3 mm form: The pellet form with 1-3 mm size range facilitates uniform loading into thermal boats or e-beam hearths, supporting both thermal/resistive and e-beam evaporation methods.
Trade-offs
- Source hardware compatibility required: Evaporation source must be matched to material behavior; specified Mo/W/Ta boat or water-cooled e-beam hearth with graphite/alumina liner, necessitating confirmation of deposition geometry before ordering.
- High melting point and density: Melting point of 1,772°C and density of 21.45 g/cm³ demand careful process parameter optimization and may require higher power or specialized liners to achieve stable evaporation rates.
