This aluminium oxide evaporation material is subject to specific processing constraints for vacuum thin-film deposition. Its compatibility with e-beam or thermal evaporation sources, liner materials, and deposition parameters must be verified before use.
- Evaporation Source Compatibility: The material must be evaporated using an e-beam hearth with graphite, Al2O3, or BN liner, or a W/Mo/Ta boat, with thermal evaporation requiring RFQ evaluation.
- Physical Form Constraint: The supplied pieces of 1-3 mm are intended for direct loading into evaporation sources and must not be further comminuted or compacted.
- Melting Point Requirement: The high melting point of 2072°C requires the evaporation source to achieve and sustain that temperature without material degradation.
- Density and Z-Ratio Consideration: The density of 3.97 g/cm³ and Z-ratio of 0.336 must be entered into the deposition controller for accurate thickness monitoring.
- Liner Material Compatibility: The liner or boat material must be chemically inert to molten Al2O3 to prevent film contamination.
Why is e-beam evaporation preferred over thermal evaporation for Al2O3 pieces?
E-beam evaporation is preferred because it delivers excellent performance with Al2O3 pieces. The source specifies that e-beam evaporation using a hearth with graphite/Al2O3/BN liner or W/Mo/Ta boat yields excellent results, while thermal evaporation requires a special request for quotation (RFQ) due to the high melting point of 2,072°C and material properties. This approach ensures optimal film quality and avoids thermal decomposition issues associated with direct thermal evaporation.
What liner or boat materials are compatible with these Al2O3 evaporation pieces?
The Al2O3 evaporation pieces are compatible with e-beam hearths using graphite, Al2O3, or BN liners, as well as W/Mo/Ta boats. For sheet2 hardware, tungsten (W) is specified. Compatibility depends on the deposition system's configuration and the material's melting point (2,072°C) and density (3.97 g/cm³); users should confirm their source geometry before ordering.
What documentation and handling precautions should be reviewed before using Al2O3 evaporation pieces?
Users should review the certificate of analysis, safety data sheet (SDS), and shipment conditions before use, as indicated in the product documentation. The material is supplied as 1–3 mm pieces with 99.5% purity and should be handled according to standard laboratory practices for fine ceramic powders. Consult the SDS for specific handling, storage, and dust control recommendations, and confirm shipment conditions with the supplier to ensure safe delivery.
This evaluation assesses Aluminium Oxide (Al2O3) evaporation material at 99.5% purity in 1-3 mm pieces, finding excellent e-beam performance and broad liner/boat compatibility, but requiring RFQ for thermal evaporation and mandatory pre-order confirmation of source geometry and documentation.
Positive
- 99.5% Purity with Defined Physical Form: Pieces sized 1-3 mm and 99.5% purity ensure reproducible source loading and consistent evaporation rates for thin-film deposition applications.
- Excellent E-Beam Performance with Hardware Flexibility: Rated excellent for e-beam evaporation and compatible with graphite, Al2O3, BN liners or W/Mo/Ta boats, allowing adaptation to existing deposition systems.
Trade-offs
- Thermal Evaporation Requires RFQ: Thermal evaporation is not directly supported for this product; buyers must submit a request for quotation, which may delay procurement for labs without e-beam capability.
- Pre-Order Confirmation Needed for Hardware and Documentation: Deposition source geometry, certificate requirements, and shipment conditions must be confirmed before ordering, adding coordination steps to the purchasing process.
