Erbium oxide evaporation material must be processed in vacuum deposition systems compatible with e-beam or thermal evaporation using specified liner or boat materials. Process parameters including melting point (2,350 °C) and Z-ratio (1.00) require precise calibration to achieve consistent film stoichiometry.
- Source Liner Compatibility: Use only graphite, alumina, or boron nitride liners for e-beam evaporation to avoid crucible contamination.
- Evaporation Method Preference: E-beam evaporation is preferred; thermal evaporation is available only by request for quotation (RFQ) due to material properties.
- Melting Point Requirement: The high melting point of 2,350 °C requires sufficient electron beam power or boat temperature capacity.
- Z-Ratio Calibration: The Z-ratio of 1.00 must be entered into the deposition controller for accurate thickness monitoring.
- Density Consideration: Material density of 8.64 g/cm³ must be accounted for in deposition rate calculations to achieve target film thickness.
What is the significance of the Z-ratio of 1.00 for Er2O3 in quartz crystal monitor calibration?
The Z-ratio of 1.00 indicates that Er2O3 has the same acoustic impedance as quartz, allowing direct use of standard tooling factors without density correction. The density of 8.64 g/cm³ and Z-ratio of 1.00 are listed in the technical specifications, simplifying thickness monitoring during e-beam evaporation.
What evaporation source materials are compatible with Er2O3 pieces given its melting point of 2,350°C?
The recommended evaporation source is e-beam hearth with graphite, Al2O3, or BN liner, or a W/Mo/Ta boat for thermal evaporation by RFQ. The melting point of 2,350°C necessitates high-temperature liners, as stated in the product's evaporation source specifications.
How does the 12 mm piece size of Er2O3 affect loading into e-beam crucibles and thermal boats?
The 12 mm piece size is specified for compatibility with standard e-beam hearths and boat geometries. The product description notes that buyers should confirm deposition source geometry and required quantity, implying that the piece size must match the source configuration to ensure proper evaporation and material utilization.
Erbium oxide (Er2O3) evaporation material in 12 mm pieces at 99.99% purity is suitable for e-beam evaporation of high-melting-point oxide films, but requires careful source matching and is not recommended for standard thermal evaporation without RFQ.
Positive
- High purity 99.99%: The 99.99% purity specification minimizes contamination in deposited thin films, supporting reproducible optical or dielectric properties in research-grade coatings.
- Defined piece size 12 mm: The 12 mm piece form factor is consistent with standard e-beam hearth loading, enabling uniform evaporation rates and predictable source depletion.
Trade-offs
- High melting point (2350°C): The 2350°C melting point requires high-energy e-beam evaporation; thermal evaporation is only possible by RFQ with specialized liners or boats, adding process complexity.
- Deposition-source compatibility needed: Evaporation source hardware must be matched to material behavior and melting point; buyers must confirm hearth liner or boat material compatibility before ordering to avoid equipment damage.
