Cerium(IV)Oxide evaporation powder necessitates precise matching of deposition source hardware and liner material to avoid contamination or process failure. Its high melting point of approximately 2600°C and a Z-ratio of 1.00 require specific loading and monitoring protocols for consistent thin-film deposition.
- Evaporation Source Compatibility: The powder must be loaded into an e-beam hearth with a graphite, Al2O3, or BN liner, or into a W, Mo, or Ta boat for thermal evaporation.
- Evaporation Method Constraints: E-beam evaporation is the preferred method, while thermal evaporation requires a request for quotation due to material-specific considerations.
- Physical Form Handling: The 325 mesh powder form requires careful handling to avoid particle loss and ensure uniform loading into the evaporation source.
- Process Monitoring Parameter: The Z-ratio of 1.00 allows direct use of quartz crystal microbalance thickness monitoring without correction factors.
What is the recommended evaporation method for Cerium(IV) Oxide powder (CeO2, 99.99%, 325 mesh) and why is thermal evaporation only available by RFQ?
E-beam evaporation is preferred for this CeO2 powder due to its high melting point of approximately 2600°C and good performance in E-beam hearths with graphite/Al2O3/BN liners or W/Mo/Ta boats. Thermal evaporation is available only by RFQ because the powder form and high melting point may require specialized crucible or source configurations to achieve reliable deposition.
What liner or boat materials are compatible with E-beam evaporation of CeO2 powder?
For E-beam evaporation of CeO2 powder, recommended liners include graphite, Al2O3, or BN for use in an E-beam hearth, or alternatively W/Mo/Ta boats. The hardware sheet2 lists Tantalum, Graphite, and W as compatible materials. The Z-ratio of 1.00 simplifies thickness monitoring.
What is the melting point of CeO2 and what infrastructure is required for its evaporation?
The melting point of CeO2 is approximately 2600°C, requiring high-power E-beam evaporation systems. The material has a density of 7.13 g/cm³ and a Z-ratio of 1.00, which facilitates straightforward quartz crystal monitoring. The powder form (325 mesh) requires careful loading into the hearth or boat to ensure uniform evaporation.
Cerium(IV) Oxide (CeO2) evaporation material, 99.99% purity, 325 mesh powder, is evaluated for e-beam evaporation with good performance using graphite/Al2O3/BN liners or W/Mo/Ta boats; its high melting point (~2600°C) and density (7.13 g/cm³) require careful source matching and process control.
Positive
- High purity for reproducible films: 99.99% purity minimizes contamination in thin-film deposition, supporting consistent optical or catalytic properties in research-grade coatings.
- Defined particle size for source loading: 325 mesh powder form facilitates uniform loading into e-beam hearths or boats, reducing variability in evaporation rate during deposition.
Trade-offs
- High melting point requires robust hardware: Melting point of ~2600°C necessitates use of graphite/Al2O3/BN liners or refractory metal boats (W/Mo/Ta), increasing infrastructure demands and consumable costs.
- Thermal evaporation limited to RFQ only: Thermal evaporation is not standard and requires a request for quotation, indicating potential process compatibility issues or need for custom setup.
