This material requires specific evaporation source hardware and process route matching to ensure proper deposition. E-beam evaporation is preferred, with thermal evaporation available by request; compatible liner materials include graphite, Al2O3, BN, W, Mo, or Ta.
- Evaporation Method: E-beam evaporation is the preferred method, but thermal evaporation may be used upon request and requires a compatible boat or liner.
- Source Hardware: The evaporation source must be fitted with a liner or boat made of graphite, alumina, boron nitride, tungsten, molybdenum, or tantalum to withstand the high melting point of Tb2O3.
- Melting Point Consideration: The material's melting point of 2387°C must be accounted for when selecting the heating method and crucible material.
- Size Compatibility: The 12 mm piece size must be compatible with the evaporation source geometry and loading mechanism.
- Pre-Use Verification: Deposition-source compatibility, material purity, and form must be confirmed before proceeding with a purchase or use.
How does the high melting point of Tb2O3 (2,387°C) affect the choice of evaporation method?
The high melting point (2,387°C) of Tb2O3 favors E-beam evaporation as the preferred method, as stated in the product specifications. Thermal evaporation is available only by RFQ, likely because standard thermal boats may not reach the required temperature uniformly. This material property directly influences the selection of deposition hardware and process route.
What liner or boat materials are compatible with Tb2O3 evaporation material?
For E-beam evaporation, the product supports graphite, Al2O3, or BN liners. For thermal evaporation (by RFQ), W, Mo, or Ta boats are compatible. These material options are explicitly listed in the evaporation source specifications, allowing users to match hardware to the Tb2O3 melting point and chemical reactivity.
What are the available pack sizes and minimum order quantity for Tb2O3 pieces?
The product is available in 25g, 100g, 500g, and 1kg pack sizes, with a minimum order quantity of 25g. The pieces are sized at 12 mm, which is specified to support source loading and evaporation process consistency. Buyers should confirm quantity and deposition source geometry before ordering.
Terbium Oxide (Tb2O3) Evaporation Material, Pieces, 99.9%, 12 mm is a research-grade compound evaporation material for vacuum thin-film deposition, supplied in 25g to 1kg packs. Its 99.9% purity and 12 mm piece form support E-beam evaporation with specific hearth liners, but the high melting point (2,387°C) and density (7.87 g/cm³) impose strict source compatibility and handling requirements.
Positive
- Defined material identity and purity: Terbium Oxide (Tb2O3) with 99.9% purity ensures clear procurement matching for deposition processes requiring consistent stoichiometry and low impurity levels.
- Specified physical form for source loading: Supplied as 12 mm pieces, this form factor facilitates loading into E-beam hearths or boats, reducing handling variability during evaporation setup.
Trade-offs
- High melting point requires robust hardware: With a melting point of 2,387°C, this material demands E-beam evaporation with graphite, Al2O3, or BN liners; thermal evaporation requires RFQ and may not be feasible with standard boats.
- Density and form may affect deposition rate control: A density of 7.87 g/cm³ combined with 12 mm piece size can lead to uneven heating or spitting if source geometry and power ramp are not optimized, requiring process validation.
