Deposition-source compatibility must be confirmed before use, including liner material and hearth type. Process parameters such as power and rate must be adjusted based on the material's melting point and Z-ratio.
- Deposition-Source Compatibility: Evaporation source hardware must be water-cooled copper e-beam hearth with compatible liner materials such as graphite, Al2O3, BN, or Ta.
- Purity and Form Consistency: The material purity of 99.99% and piece size of 3-6 mm must be maintained to achieve reproducible film properties.
- Process Parameter Matching: The melting point of 2,227°C and Z-ratio of 0.36 must be considered when setting e-beam power and deposition rate.
- Pack Size Selection: Available pack sizes of 25g, 100g, 500g, and 1kg require quantity confirmation based on deposition run requirements.
How does the melting point of 2,227°C and density of 13.31 g/cm³ influence the selection of hearth liner materials for hafnium e-beam evaporation?
The high melting point (2,227°C) and density (13.31 g/cm³) of hafnium require hearth materials that withstand thermal stress and prevent contamination. Compatible liners include graphite, Al2O3, BN, or Ta, as specified in the product description for water-cooled copper e-beam hearths.
What is the role of the Z-ratio of 0.36 in hafnium evaporation material for e-beam deposition process control?
The Z-ratio of 0.36 is a critical parameter for e-beam deposition rate monitoring and control. It indicates the acoustic impedance mismatch between the material and the quartz crystal sensor, which must be factored into the film thickness calibration for hafnium deposition.
What pack sizes are available for hafnium evaporation material and what procurement verification steps are required before ordering?
The hafnium evaporation material is available in pack sizes of 25g, 100g, 500g, and 1kg, with a minimum order quantity of 25g. Before ordering, buyers must confirm model, purity, form, size range, pack size, and deposition-source compatibility, as noted in the procurement checklist.
This hafnium evaporation material offers 99.99% purity in 3-6 mm pieces, optimized for e-beam deposition with water-cooled copper hearths, though its high melting point (2,227°C) and Z-ratio (0.36) require careful process tuning and specialized hardware.
Positive
- High purity 99.99%: The 99.99% purity specification ensures consistent thin-film composition and minimizes contamination in vacuum deposition processes.
- Controlled particle size 3-6 mm: Pieces sized 3-6 mm enable uniform loading into e-beam hearths and predictable evaporation behavior during deposition.
Trade-offs
- Requires specific e-beam hardware: The material is optimized for water-cooled copper e-beam hearths with compatible liners (graphite, Al2O3, BN, Ta), imposing infrastructure requirements for deposition.
- High melting point and Z-ratio: A melting point of 2,227°C demands high-energy e-beam sources, and a Z-ratio of 0.36 may require recalibration of quartz crystal monitors for accurate film thickness control.
