This cerium oxide evaporation material requires careful matching of deposition source hardware including liner material and boat type to avoid contamination and ensure efficient evaporation. The material's high melting point of approximately 2600°C and density of 7.13 g/cm³ influence the required electron beam power and deposition rate.
- Evaporation Source Matching: Select an E-beam hearth with graphite, Al2O3, or BN liner, or use a W/Mo/Ta boat to prevent chemical reaction with the molten material.
- Particle Size Consideration: The 8-28 nm particle size fraction must be assessed for loading uniformity and vaporization consistency in the crucible.
- Melting Point Compatibility: The ~2600°C melting point requires sufficient electron beam power or thermal source temperature to achieve stable evaporation.
- Purity Requirement: The 99.99% purity grade minimizes film contamination, but the evaporation source must be clean and dedicated to avoid cross-contamination.
- Z-Ratio Calibration: A Z-ratio of 1.00 indicates the material's acoustic impedance, which is used for quartz crystal microbalance thickness monitoring calibration.
Why is thermal evaporation not recommended for CeO2 evaporation material and available only by RFQ?
E-beam evaporation is preferred for this CeO2 material due to its high melting point (~2600°C) and piece form (8–28 nm). Thermal evaporation is available by RFQ only, as it may require specialized equipment adjustments. The product specification states that E-beam performance with a graphite/Al2O3/BN liner or W/Mo/Ta boat is rated as good.
Which boat or liner materials are compatible with E-beam evaporation of CeO2 pieces?
Compatible liner materials for E-beam evaporation include graphite, Al2O3, and BN. Compatible boat materials include W, Mo, and Ta. The product also lists Tantalum and Graphite as sheet2 hardware options for the evaporation source.
What is the significance of the 8–28 nm piece size for this CeO2 evaporation material?
The 8–28 nm piece size is specified to facilitate uniform source loading and consistent evaporation behavior in vacuum deposition systems. This sizing supports reliable material handling and controlled vaporization, as indicated in the product performance features.
Cerium(IV) Oxide (CeO2) evaporation material in pieces form with 99.99% purity and 8–28 nm particle size, suitable for E-beam evaporation with good performance using graphite, Al2O3, or BN liners, but requires careful hardware matching due to high melting point (~2600 °C) and specified evaporation method constraints.
Positive
- High purity and defined particle size: 99.99% purity and 8–28 nm piece size ensure consistent stoichiometry and controlled evaporation behavior for repeatable thin-film deposition.
- E-beam evaporation compatibility: Good E-beam performance with standard liner materials (graphite, Al2O3, BN) and refractory metal boats (W, Mo, Ta) simplifies integration into existing deposition systems.
Trade-offs
- High melting point requires specialized equipment: Melting point of ~2600 °C necessitates E-beam evaporation as the primary method; thermal evaporation is only available by RFQ, limiting process flexibility.
- Mandatory procurement verification: Buyer must confirm deposition-source geometry, hardware compatibility, and pack size before ordering, as material behavior and film requirements are strongly system-dependent.
