Gadolinium pellets require careful matching of evaporation source hardware and process parameters to achieve consistent thin-film deposition. The material's melting point of 1,313°C and Z-ratio of 0.67 dictate specific boat or liner materials and deposition rate calibration.
- Deposition Source Compatibility: Use only Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner to avoid contamination or incomplete evaporation.
- Process Route Selection: Select E-beam or thermal/resistive evaporation based on the material's melting point and required film stoichiometry.
- Size Range Handling: Confirm that the 1–10 mm pellet size is compatible with the source crucible or boat geometry to ensure uniform feeding.
- Z-Ratio Calibration: Incorporate the Z-ratio of 0.67 into quartz crystal monitor calibration for accurate film thickness control.
- Pre-Deposition Verification: Verify purity (99.99%) and certificate of analysis against process requirements before loading the evaporation source.
This procedure outlines the key steps to prepare and deploy gadolinium pellets in a vacuum deposition system. Proper matching of source hardware and process parameters ensures consistent film quality.
Required Equipment: Ta/W boat, Ta liner, Water-cooled e-beam hearth with liner
- Confirm Source Compatibility
Confirm that the evaporation source hardware (Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner) is compatible with the gadolinium pellets. - Select Evaporation Method
Select the evaporation method (E-beam or thermal/resistive) based on the material's melting point of 1,313°C and desired film properties. - Load Pellets into Source
Load the gadolinium pellets into the chosen boat or liner, ensuring the 1–10 mm size range fits the source geometry. - Calibrate Thickness Monitor
Calibrate the quartz crystal monitor using the Z-ratio of 0.67 for accurate film thickness control. - Set Evaporation Parameters
Set the evaporation power and ramp rate according to the material's melting point and system specifications. - Initiate Deposition
Initiate the deposition process under vacuum and monitor the film growth rate.
What melting point does this gadolinium evaporation material have and how does it influence deposition source selection?
The gadolinium evaporation material has a melting point of 1,313. This moderate melting point makes it suitable for both thermal resistive and e-beam evaporation. However, source selection should consider the need for Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner to avoid contamination and ensure proper evaporation.
Can these gadolinium pellets be used for both thermal and e-beam evaporation processes?
Yes, the product is specified for both e-beam and thermal/resistive evaporation by RFQ. The recommended evaporation sources include Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner. Buyers should confirm compatibility with their deposition system before ordering.
What documentation and handling considerations are provided with this gadolinium evaporation material?
The product description indicates that certificates, safety data sheets, shipment conditions, and export requirements can be reviewed against laboratory use requirements. Buyers should request these documents to ensure proper handling and storage, especially given the high purity (99.99%) and pellet form which may be less reactive than powders.
Gadolinium (Gd) evaporation pellets at 99.99% purity (1-10 mm) offer a defined material identity and physical form for e-beam or thermal evaporation, with a melting point of 1,313°C and Z-ratio of 0.67 requiring process calibration. The product is available in 100g, 500g, and 1kg packs for laboratory-scale deposition.
Positive
- High purity 99.99% specification: The 99.99% purity grade enables controlled film deposition with reduced impurity incorporation, suitable for research-grade thin-film applications.
- Pellet form with source compatibility: Supplied as 1-10 mm pellets compatible with Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner, supporting both thermal and e-beam evaporation methods.
Trade-offs
- Melting point constraint: With a melting point of 1,313°C, the material requires careful temperature control and source matching to avoid premature melting or process instability.
- Z-ratio calibration requirement: The Z-ratio of 0.67 deviates from unity, necessitating calibration of quartz crystal microbalance thickness monitors for accurate film thickness control during evaporation.
