This material requires careful matching to evaporation source hardware and process conditions to achieve desired film properties. Confirmation of purity, form, and deposition-source compatibility is essential before ordering.
- Deposition source compatibility: Use only with Mo/W/Ta boat or water-cooled e-beam hearth with graphite/alumina liner.
- Process route matching: Match evaporation method (thermal/resistive or e-beam) to material behavior and melting point.
- Purity verification: Confirm the 99.95% purity grade meets the specific film requirements.
- Documentation review: Review certificate, safety data sheet, and shipment conditions against laboratory use requirements.
- Sizing confirmation: Verify the 1-3 mm pellet size is suitable for the source loading geometry.
What is the significance of the Z-ratio of 0.245 for platinum evaporation pellets in e-beam deposition?
The Z-ratio of 0.245 is a material-specific parameter used in quartz crystal microbalance (QCM) rate monitoring during e-beam evaporation. It affects the acoustic impedance correction factor, so this value must be input into the deposition controller to ensure accurate film thickness measurement. The product datasheet explicitly lists Z-Ratio: 0.245 for the AF-PTPEL-999513MM pellets.
Which boat and liner materials are compatible with platinum evaporation pellets at the 1,772°C melting point?
The product is specified for use with molybdenum, tungsten, or tantalum (Mo/W/Ta) boats for thermal/resistive evaporation, or a water-cooled e-beam hearth with graphite or alumina liners. These materials are selected for thermal stability and non-reactivity at platinum's melting point of 1,772°C, as stated in the technical specifications.
How does the 1–3 mm pellet size influence loading and evaporation uniformity in vacuum deposition?
The 1–3 mm pellet size is specified to enable consistent, reproducible loading into Mo/W/Ta boats and e-beam hearths. This size range promotes uniform heating and controlled evaporation rates, reducing the risk of spitting or non-uniform film deposition. The product description explicitly lists Pellets 1–3 mm as the configured particle size to support source loading and evaporation review.
Platinum (Pt) evaporation pellets with 99.95% purity and 1–3 mm size are designed for thermal and e-beam evaporation in vacuum thin-film deposition; the high melting point (1,772 °C) and high density (21.45 g/cm³) require careful matching of source hardware and process parameters for reliable film deposition.
Positive
- High purity 99.95% platinum: 99.95% purity specification supports consistent film composition and reduces contamination risk in sensitive thin-film applications.
- Defined 1–3 mm pellet form: Pellet form with 1–3 mm size range enables controlled loading into thermal or e-beam evaporation sources and uniform evaporation behavior.
Trade-offs
- Requires source hardware matching: Evaporation source hardware (Mo/W/Ta boat or water-cooled e-beam hearth with graphite/alumina liner) must be matched to material behavior and melting point for successful deposition.
- High melting point constraint: Melting point of 1,772 °C demands high-power deposition equipment and careful process control to avoid source damage or incomplete evaporation.
