Evaporation of Tb2O3 pieces requires a vacuum deposition system with an E-beam or thermal evaporation source. The source must be configured with a graphite, Al2O3, or BN liner, or a W/Mo/Ta boat, to withstand the high melting temperature and prevent chemical reaction.
- Evaporation Method: Use E-beam evaporation as the preferred method; thermal evaporation requires a special request for quotation.
- Source Liner Selection: Select a graphite, Al2O3, or BN liner for the E-beam hearth to avoid contamination and withstand the high melting point of 2387°C.
- Boat Material for Thermal Evaporation: For thermal evaporation, use a tungsten, molybdenum, or tantalum boat to ensure compatibility.
- Piece Size Compatibility: The 12 mm piece size dictates the source cavity dimensions required for proper loading and evaporation.
- Process Route Matching: Confirm that the evaporation source hardware and process route are matched to the material's melting point and film requirements.
What is the melting point and density of Tb2O3 evaporation material and how do they affect deposition?
The melting point of Terbium Oxide (Tb2O3) is 2,387 °C and density is 7.87 g/cm³. These high values require high-energy evaporation methods such as e-beam evaporation, which is the preferred method, or thermal evaporation by RFQ using appropriate liners or boats. The density influences film compactness and uniformity during thin-film deposition.
What evaporation source hardware is compatible with Tb2O3 pieces?
The product is compatible with e-beam hearths using graphite, Al2O3, or BN liners, or with W/Mo/Ta boats. E-beam evaporation is the preferred method; thermal evaporation is available by RFQ. The 12 mm piece size is designed for standard source loading in vacuum deposition systems.
What documentation and safety considerations should be reviewed before using Tb2O3 evaporation material?
Buyers should review the certificate of analysis, safety data sheet, shipment conditions, and export requirements before use. The product is research-grade with 99.97% purity and requires confirmation of material identity, form, pack size, and deposition-source compatibility. Proper handling procedures for rare earth oxide materials should be followed.
Terbium Oxide (Tb2O3) evaporation material in 12 mm pieces at 99.97% purity is evaluated for E-beam evaporation deposition of thin films, with a high melting point of 2,387°C and density of 7.87 g/cm³, requiring specific source hardware and process matching.
Positive
- High purity for film consistency: 99.97% purity specification supports reproducible thin-film stoichiometry and reduces contamination risk in optical or electronic layer deposition.
- Defined physical form for loading: Pieces sized at 12 mm facilitate controlled loading into E-beam hearths or boats, minimizing source spitting and improving evaporation rate stability.
Trade-offs
- High melting point requires robust hardware: Melting point of 2,387°C necessitates E-beam evaporation with graphite, Al2O3, or BN liners; thermal evaporation requires RFQ and may not be feasible with standard boats.
- Deposition method compatibility constraints: E-beam evaporation is preferred; thermal evaporation is only available by RFQ and requires specific boat or liner materials (W/Mo/Ta), limiting process flexibility.
