This pure metal evaporation material requires selection of compatible evaporation source hardware and process route to match material behavior and film requirements. Buyers must confirm deposition source geometry, certificate requirements, and shipment conditions prior to quotation.
- Evaporation Source Compatibility: Use Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner for E-beam or thermal/resistive evaporation.
- Pellet Size for Loading: Select the 1-10 mm pellet size range to match the source loading geometry and ensure uniform evaporation.
- Purity Grade Consideration: The 99.9% purity specification allows comparison with standard and high-purity grades for application-specific film quality.
- Melting Point and Process Parameters: Set evaporation parameters based on the melting point of 1,412°C and Z-ratio of 0.6 for accurate process control.
- Documentation and Certification: Review certificate of analysis, safety data sheet, and shipment conditions to confirm compliance with laboratory use requirements.
What is the significance of the Z-ratio of 0.6 for Dysprosium evaporation material in quartz crystal thickness monitoring?
The Z-ratio of 0.6 is a critical parameter for accurate film thickness monitoring using a quartz crystal microbalance (QCM) during deposition of Dysprosium. It corrects the acoustic impedance mismatch between the quartz crystal and the deposited Dy film, and must be entered into the deposition controller to avoid systematic thickness errors. This value is explicitly listed in the product specifications for the 99.9% pure Dy pellets.
What evaporation source hardware is recommended for Dysprosium pellets to avoid contamination or damage during thin-film deposition?
Dysprosium pellets (1-10 mm, 99.9% purity) are compatible with Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner for either E-beam or thermal/resistive evaporation. The source explicitly recommends these hardware options based on the material's melting point of 1,412 °C and density of 8.55 g/cm³. Using a liner is essential to prevent direct contact between molten Dy and the crucible, avoiding contamination and crucible damage.
Does Dysprosium evaporation material require special storage or handling precautions due to its rare earth metal reactivity?
Dysprosium is a reactive rare earth metal that oxidizes in air, especially in pellet form (1-10 mm), which can degrade evaporation quality. The product documentation mandates reviewing the safety data sheet and confirming shipment conditions before ordering. For laboratory use, the pellets should be stored in an inert atmosphere or vacuum-sealed to prevent oxidation, as indicated by the procurement check requirement for condition review.
This dysprosium evaporation pellet material offers 99.9% purity in a defined 1-10 mm pellet form, suitable for e-beam or thermal evaporation with compatible sources, but requires careful hardware matching and pre-order confirmation of source geometry and handling conditions.
Positive
- Defined Purity and Physical Form: The 99.9% purity and pellet form (1-10 mm) ensure consistent evaporation behavior and simplify source loading for e-beam or thermal evaporation systems.
- Scalable Pack Size Options: Available in 25 g to 1 kg packs allows laboratories to match procurement to experimental scale without over-purchasing.
Trade-offs
- Evaporation Source Compatibility Required: The high melting point (1,412°C) and Z-ratio (0.6) necessitate specific source materials (Ta/W boat, Ta liner, or water-cooled e-beam hearth) and RFQ confirmation, limiting use in generic evaporation systems.
- Pre-Order Technical Confirmation Needed: Buyers must confirm deposition source geometry, certificate requirements, and shipment conditions before quotation, adding a pre-purchase technical evaluation step.
