Hafnium oxide evaporation powder requires e-beam evaporation with specific hearth liners (graphite, Al2O3, BN) or refractory metal boats. The material's high melting point (2,758 °C) and Z-ratio of 1.00 necessitate process matching to deposition source geometry and evaporation method.
- Evaporation Method Constraint: E-beam evaporation is preferred; thermal evaporation requires RFQ confirmation.
- Liner Material Constraint: Use graphite, Al2O3, or BN liners for e-beam hearth, or W/Mo/Ta boats.
- Particle Size Constraint: Powder particle size of 55-75 nm must be confirmed for source loading and evaporation review.
- Deposition Compatibility Constraint: Deposition source hardware and process route must be matched to material behavior and melting point.
Why is e-beam evaporation performance rated as 'Fair' for this HfO2 powder?
The e-beam evaporation performance is rated as 'Fair' due to the high melting point of 2,758 °C and the powder form (55–75 nm), which can cause non-uniform melting or splattering. E-beam evaporation is the preferred method, but thermal evaporation is available by RFQ. Using a graphite, Al2O3, or BN liner, or a W/Mo/Ta boat is recommended to improve performance.
What crucible or boat materials are compatible with evaporating HfO2 powder at 2,758 °C?
Compatible source materials include e-beam hearths with graphite, Al2O3, or BN liners, or boats made of tungsten, molybdenum, or tantalum. The product is designed for direct loading in the hearth ('Sheet2 hardware: Direct in Hearth'). Buyers must verify deposition source geometry and liner compatibility before ordering.
How does the melting point of 2,758 °C affect the recommended evaporation method and hardware?
The melting point of 2,758 °C necessitates e-beam evaporation as the preferred method, as thermal evaporation is only available by special RFQ. This high temperature also requires the use of refractory liners or boats (graphite, Al2O3, BN, or W/Mo/Ta) that can withstand the heat without degrading or contaminating the film.
This HfO2 evaporation material (99.99% purity, 55-75 nm powder) offers a defined particle size range and high purity for thin-film deposition, but its fair e-beam performance rating and specific source hardware requirements mandate careful process matching before acquisition.
Positive
- High Purity (99.99%) for Consistent Film Quality: The 99.99% purity specification reduces contamination risk in thin-film deposition, enabling reliable comparison with standard and high-purity grades.
- Defined Nanoparticle Size Range (55–75 nm): The narrow particle size distribution supports uniform source loading and predictable evaporation behavior in vacuum deposition systems.
Trade-offs
- Fair E-beam Evaporation Performance: The product's e-beam evaporation performance is rated as 'Fair', indicating potential limitations in deposition rate or film quality compared to higher-performing materials; users may need to optimize parameters or consider alternative methods.
- Mandatory Deposition-Source Compatibility Check: The material requires specific evaporation source hardware (e.g., graphite, Al2O3, BN liner, or W/Mo/Ta boat) and may not be suitable for all e-beam or thermal evaporation systems; compatibility must be confirmed before procurement.
