Hafnium (Hf) evaporation material must be processed via e-beam evaporation using a water-cooled copper hearth. Compatible liner materials include graphite, alumina, boron nitride, or tantalum to prevent contamination.
- E-beam Evaporation Requirement: Hafnium pieces require e-beam evaporation as the preferred deposition method.
- Hearth Compatibility: The material must be used with a water-cooled copper e-beam hearth.
- Liner Selection: Compatible liners include graphite, Al2O3, BN, or Ta to avoid chemical reaction.
- Melting Point Consideration: The melting point of 2227°C requires high-power electron beam settings.
- Z-Ratio Calibration: The Z-ratio of 0.36 must be entered into the deposition controller for accurate rate monitoring.
What is the melting point of this hafnium evaporation material and how does it influence E-beam evaporation?
The melting point is 2,227°C. This high melting point necessitates the use of E-beam evaporation as the preferred method, as it can deliver sufficient energy to melt and vaporize hafnium. The product is designed for use with a water-cooled copper e-beam hearth and compatible liners (graphite, Al2O3, BN, Ta) to withstand the thermal load.
What liner materials are compatible with hafnium evaporation in an E-beam system?
The product specifies compatibility with graphite, Al2O3, BN, and Ta liners when used with a water-cooled copper e-beam hearth. This allows researchers to select the appropriate liner based on their deposition system configuration and material interaction constraints.
What pack sizes are available for this hafnium evaporation material and what is the minimum order quantity?
Available pack sizes are 25g, 100g, 500g, and 1kg, with a minimum order quantity of 25g. Indicative price tiers are provided, with the 1kg pack offering the lowest cost per gram at USD 450. Buyers should confirm pack size requirements before quotation.
Hafnium (Hf) evaporation material (99.95%, 3-6 mm pieces) offers high purity suitable for thin-film deposition, but its high melting point (2,227°C) and Z-ratio (0.36) impose specific hardware and monitoring requirements.
Positive
- High purity and defined physical form: 99.95% purity and 3-6 mm pieces enable precise control in vacuum thin-film deposition workflows, matching to standard E-beam evaporation sources.
- Broad evaporation source compatibility: Compatible with water-cooled copper E-beam hearth and graphite/Al2O3/BN/Ta liners, offering flexibility in deposition hardware integration.
Trade-offs
- High melting point requires E-beam hardware: Melting point of 2,227°C limits thermal evaporation; E-beam evaporation is preferred, requiring compatible high-power source infrastructure.
- Z-ratio demands deposition rate calibration: Z-ratio of 0.36 indicates significant acoustic impedance mismatch, necessitating careful quartz crystal microbalance calibration for accurate film thickness monitoring.
