This evaporation material requires specific deposition-source hardware and process matching to achieve optimal film quality. The material's high melting point and density impose constraints on source liner selection and e-beam power requirements.
- Evaporation method preference: E-beam evaporation is the preferred deposition method; thermal evaporation requires RFQ confirmation for compatibility.
- Source liner and boat materials: E-beam hearth must use graphite, Al2O3, or BN liner or W/Mo/Ta boat.
- Sheet hardware specifications: Tantalum and graphite are specified sheet hardware materials; tungsten is listed for boat options.
- Melting point constraint: A melting point of approximately 2,600 °C requires refractory liner materials and sufficient source power.
- Z-ratio for deposition monitoring: A Z-ratio of 1.00 is provided for calibration of quartz crystal microbalance thickness monitors.
How does the 99.975% purity of CeO2 evaporation material affect film quality for optical coatings?
The 99.975% purity specification indicates a high-purity grade suitable for most thin-film applications. For critical optical coatings requiring extremely low trace contaminants, an RFQ-controlled higher-purity grade may be necessary, as the product description notes that this grade supports comparison between standard, high-purity, and RFQ-controlled grades. The exact impurity levels are not quantified in the source, but the stated purity is sufficient for standard e-beam evaporation processes.
Which crucible or liner materials are compatible with e-beam evaporation of CeO2?
CeO2 evaporation material performs well with e-beam evaporation using a graphite, Al2O3, or BN liner, or alternatively a W/Mo/Ta boat. Thermal evaporation is possible by RFQ inquiry. The high melting point of ~2,600°C favors e-beam over thermal evaporation, and the specified liner and boat materials are recommended for process reliability.
What is the significance of the Z-ratio of 1.00 for CeO2 in quartz crystal microbalance (QCM) monitoring?
The Z-ratio of 1.00 indicates that the acoustic impedance of CeO2 matches that of quartz, simplifying film thickness monitoring because the tooling factor is close to unity. This value, provided in the technical specifications, enables accurate thickness control during deposition without requiring significant correction factors.
Cerium(IV)Oxide (CeO2) evaporation material in 325-mesh pieces at 99.975% purity is evaluated for E-beam evaporation with good performance using graphite/Al2O3/BN liners or refractory metal boats, though its high melting point (~2600°C) and density (7.13 g/cm³) impose specific source and liner requirements for stable deposition.
Positive
- High-purity 99.975% CeO2 pieces: The 99.975% purity specification supports consistent thin-film stoichiometry and reduces contamination risk in optical or catalytic coating applications.
- E-beam evaporation compatibility with multiple liners: Good E-beam performance is achievable with graphite, Al2O3, or BN liners, as well as W/Mo/Ta boats, providing flexibility in deposition hardware configuration.
Trade-offs
- High melting point requires robust thermal management: With a melting point of approximately 2600°C, the material demands high-power E-beam sources or specialized thermal setups, increasing infrastructure and energy requirements.
- Thermal evaporation requires RFQ confirmation: Thermal evaporation is not standard for this material and must be confirmed via request for quotation, limiting process flexibility without prior engineering assessment.
