This evaporation material requires specific deposition hardware and parameter matching. The material's physical properties dictate power settings and thickness monitoring adjustments.
- Liner and Boat Compatibility: Use e-beam hearth with graphite, Al2O3, or BN liner, or W/Mo/Ta boat for thermal evaporation.
- Evaporation Method Preference: E-beam evaporation is recommended; thermal evaporation requires prior quotation.
- Melting Point Consideration: The high melting point of 2072 °C necessitates sufficient power to achieve evaporation.
- Z-Ratio Calibration: The Z-ratio of 0.336 must be set in the deposition controller for accurate film thickness monitoring.
- Density in Material Loading: The density of 3.97 g/cm³ should be used for calculating material charge weight.
What is the recommended evaporation method for Al2O3 pieces (99.99%, 1-3 mm) and why is thermal evaporation only available by RFQ?
E-beam evaporation is preferred and yields excellent performance for this material. Thermal evaporation is only available by RFQ because the high melting point of 2,072°C and the material's properties may require specialized source configurations to avoid contamination or incomplete evaporation, as noted in the product specifications.
Which crucible liner or boat materials are compatible with E-beam evaporation of Al2O3 pieces?
The recommended E-beam hearth liners include graphite, Al2O3, or BN. For boat evaporation, tungsten (W), molybdenum (Mo), or tantalum (Ta) can be used, with the product listing 'Sheet2 hardware: Tungsten' as a reference. Compatibility with the deposition source should be confirmed before ordering.
What are the critical procurement checks before ordering Al2O3 evaporation material?
Confirm model, purity (99.99%), form (pieces), size range (1-3 mm), pack size, and deposition-source compatibility before quotation. Also review the certificate, safety data sheet, shipment conditions, and export requirements. The material's density (3.97 g/cm³) and Z-ratio (0.336) are important for process control and should be matched to the evaporation system.
The 99.99% pure Al2O3 pieces (1-3 mm) deliver excellent E-beam evaporation performance with minimal contamination, but labs requiring thermal evaporation must request via RFQ and source compatible liners or boats for optimal results.
Positive
- High purity 99.99% for quality films: The 99.99% purity minimizes elemental contamination in deposited thin films, ensuring consistent optical or dielectric properties.
- Optimized 1-3 mm particle size: The pieces size range of 1-3 mm facilitates uniform loading in E-beam hearths and boats, promoting stable evaporation rates.
Trade-offs
- Thermal evaporation requires RFQ: Thermal evaporation is not a standard option and must be requested via quotation, limiting immediate process flexibility for labs relying solely on thermal sources.
- Requires specific liner materials: Optimal E-beam performance depends on using graphite, Al2O3, or BN liners, or W/Mo/Ta boats; these consumables may require separate procurement and compatibility verification.
