Evaporation of hafnium requires a vacuum environment and a water-cooled copper e-beam hearth with a compatible liner such as graphite, Al2O3, BN, or Ta. The material's melting point of 2227°C, density of 13.31 g/cm³, and Z-ratio of 0.36 must be used to calibrate deposition rate and thickness.
- Evaporation Source Configuration: Load the hafnium pieces into a water-cooled copper e-beam hearth to prevent contamination and ensure proper thermal management.
- Liner Material Selection: Select a compatible liner material such as graphite, aluminum oxide, boron nitride, or tantalum to avoid chemical reactions at high temperatures.
- Vacuum Environment Requirement: Operate the e-beam evaporation under high vacuum to prevent oxidation of the hafnium melt and ensure film purity.
- Deposition Rate Monitoring: Use the Z-ratio of 0.36 and density of 13.31 g/cm³ to calibrate the quartz crystal microbalance for accurate thickness control.
Why is a 3–6 mm piece size specified for hafnium evaporation material, and how does it affect e-beam deposition performance?
The 3–6 mm piece size is specified to facilitate source loading and consistent evaporation in e-beam systems. Hafnium has a melting point of 2,227°C, density of 13.31 g/cm³, and a Z-ratio of 0.36, which influence deposition rate and film uniformity. The water-cooled copper e-beam hearth with compatible liners (graphite, Al2O3, BN, Ta) is recommended to handle the high melting point and thermal characteristics.
Which liner materials are compatible with hafnium evaporation in e-beam systems?
Compatible liner materials include graphite, Al2O3, BN, and Ta. The preferred evaporation method is e-beam using a water-cooled copper hearth. Buyers should confirm deposition source geometry and liner compatibility before ordering.
What documentation and procurement steps should be verified before ordering hafnium evaporation material?
Before ordering, confirm model, purity (99.9%), form (pieces), size range (3–6 mm), pack size, and deposition-source compatibility. Review the certificate of analysis, safety data sheet, shipment conditions, and export requirements to ensure alignment with laboratory use and regulatory compliance.
Hafnium (Hf) evaporation material, 99.9% purity, 3-6 mm pieces, is suitable for E-beam thin-film deposition requiring a water-cooled copper hearth. The specified size and purity support consistent evaporation, but compatibility with existing deposition hardware must be verified prior to purchase.
Positive
- High-purity 99.9% hafnium pieces: The 99.9% purity ensures minimal contamination during thin-film deposition, critical for consistent film properties in research and production.
- Specified 3-6 mm size range: The defined piece size facilitates uniform loading into E-beam evaporation sources, improving deposition rate stability and reducing source spitting.
Trade-offs
- E-beam evaporation infrastructure required: Optimal performance requires a water-cooled copper E-beam hearth with compatible liners (graphite, Al2O3, BN, or Ta), limiting use to facilities with this specific equipment.
- Pre-use procurement verification necessary: Buyers must confirm deposition source geometry, required quantity, certificate requirements, and shipment conditions before order, adding administrative overhead to procurement.
