This material requires careful matching of deposition source hardware to achieve optimal e-beam evaporation performance. Compatibility with specific liner and boat materials must be verified before use to prevent contamination or process failure.
- Deposition Source Matching: Match the evaporation source hardware and process route to the material's melting point and evaporation behavior to ensure successful film deposition.
- Liner and Boat Selection: Select e-beam hearth liners made of graphite, alumina (Al2O3), or boron nitride (BN), or use boats of tungsten, molybdenum, or tantalum for optimal performance.
- Thermal Evaporation Limitation: Thermal evaporation is not recommended without RFQ due to the high melting point of approximately 2600°C, which may exceed standard thermal source capabilities.
- Material Form Handling: Handle the pieces (325 mesh) carefully to avoid particle size segregation or contamination before loading into the deposition source.
- Pre-Use Verification: Verify material identity, purity, form, and pack size against the deposition system requirements before opening the container.
What is the recommended evaporation method for Cerium(IV)Oxide (CeO2) pieces, and why is e-beam evaporation preferred over thermal evaporation?
E-beam evaporation is the preferred method for CeO2 pieces due to its good performance with this material. Thermal evaporation is available only by RFQ (request for quotation). For e-beam deposition, a graphite, Al2O3, or BN liner is recommended, or a W, Mo, or Ta boat can be used. The high melting point of approximately 2600°C makes e-beam evaporation more suitable for controlled thin-film deposition.
Which liner or boat materials are compatible with e-beam or thermal evaporation of CeO2 pieces?
For e-beam evaporation, a graphite, Al2O3, or BN liner is recommended, or alternatively a tungsten (W), molybdenum (Mo), or tantalum (Ta) boat. For additional sheet hardware, tantalum and graphite are specified. These material choices are based on the high melting point (~2600°C) and chemical compatibility with CeO2 during evaporation.
What are the melting point, density, and Z-ratio of CeO2 evaporation material, and how do they influence deposition process parameters?
Cerium(IV)Oxide (CeO2) has a melting point of approximately 2600°C, a density of 7.13 g/cm³, and a Z-ratio of 1.00. These physical properties dictate the required evaporation source power, deposition rate, and film uniformity. The high melting point necessitates e-beam evaporation for reliable sublimation, while the Z-ratio of 1.00 simplifies quartz crystal monitor calibration for thickness control.
This Cerium(IV) Oxide evaporation material offers 99.99% purity in 325 mesh pieces, optimized for e-beam evaporation with good performance using graphite, Al2O3, BN, or W/Mo/Ta liners, but its high melting point (~2600°C) restricts thermal evaporation to RFQ-only and requires careful process matching.
Positive
- High purity and defined particle size: 99.99% purity and 325 mesh sizing ensure batch-to-batch consistency for reproducible thin-film deposition in vacuum processes.
- Good e-beam performance with liner flexibility: E-beam evaporation performance is rated good with compatibility across graphite, Al2O3, BN liners or W/Mo/Ta boats, offering process flexibility for different deposition systems.
Trade-offs
- High melting point limits deposition methods: Melting point of ~2600°C requires high-power e-beam sources and refractory liners; thermal evaporation is not standard and must be requested via RFQ, increasing equipment and process complexity.
- Pre-application process validation required: Buyers must confirm deposition source geometry, pack size, certificate requirements, and shipment conditions before ordering, as mismatches can delay or prevent successful deposition.
