The material requires specific evaporation source hardware (Ta/W boat, Ta liner, or water-cooled e-beam hearth) and must be matched to the deposition method. The pellet size of 1-10 mm and purity of 99.99% impose constraints on loading geometry and film quality requirements.
- Source Compatibility: Verify that the evaporation source boat or liner material is compatible with holmium at the required deposition temperature.
- Pellet Size: Confirm that the 1-10 mm pellet size allows proper loading and uniform evaporation in the chosen source.
- Purity Grade: Ensure the 99.99% purity grade meets the film quality requirements for the intended application.
- Process Matching: Select the evaporation method (e-beam or thermal/resistive) based on the material's melting point of 1474°C and the required deposition rate.
- Thickness Monitoring: Use the Z-ratio of 0.58 for accurate film thickness monitoring during deposition.
How does the 99.99% purity specification of Holmium evaporation pellets influence thin-film quality?
The 99.99% purity ensures minimal trace metal contamination, which is critical for achieving consistent stoichiometry and electrical properties in deposited films. This research-grade material is supplied as 1-10 mm pellets to facilitate uniform evaporation in both e-beam and thermal processes.
What evaporation source configurations are compatible with Holmium pellets (99.99%, 1-10 mm)?
Compatible evaporation sources include Ta/W boats, Ta liners, and water-cooled e-beam hearths with liners. Both e-beam and thermal/resistive evaporation methods can be used, but the specific source and process should be confirmed via RFQ to match the material's melting point (1,474°C) and density (8.8 g/cm³).
What available pack sizes and price tiers exist for Holmium evaporation material (SKU AF-HOPEL-4N110MM)?
The product is available in 100g, 500g, and 1kg packs with indicative price tiers at USD 400, 1000, and 1400 respectively. A minimum order quantity of 100g applies. Buyers must confirm deposition source geometry and required quantity before ordering.
Holmium (Ho) evaporation pellets with 99.99% purity and 1–10 mm size range are optimized for E-beam or thermal/resistive evaporation, requiring compatible source hardware (Ta/W boat or water-cooled e-beam hearth) and careful process tuning due to a melting point of 1,474°C and Z-Ratio of 0.58.
Positive
- High purity 99.99%: The 99.99% purity specification minimizes contaminant incorporation into thin films, ensuring reproducible electronic and optical properties in deposition workflows.
- Pellet form with defined size range: Pellets sized 1–10 mm are designed for consistent loading into evaporation sources, reducing particle bridging and enabling stable feed rates during long deposition runs.
Trade-offs
- Specific source hardware required: Evaporation requires Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner; direct compatibility with other boat materials or unlined hearths is not stated and may necessitate RFQ confirmation.
- High melting point and Z-Ratio constraints: With a melting point of 1,474°C and Z-Ratio of 0.58, process parameters must be precisely controlled to achieve stoichiometric transfer and prevent source wetting or alloying.
