This Terbium Oxide evaporation material requires specific deposition source hardware and high-temperature processing. The powder form and purity level impose handling and compatibility constraints for vacuum thin-film deposition.
- Evaporation Source Compatibility: The material requires an e-beam hearth with graphite, Al2O3, or BN liner, or a W, Mo, or Ta boat for thermal evaporation.
- Evaporation Method Preference: E-beam evaporation is the preferred method; thermal evaporation is available by RFQ.
- Melting Point Constraint: The material has a melting point of 2,387°C, requiring high-temperature deposition capability.
- Particle Size Consideration: The 325 mesh powder size must be compatible with the deposition source loading mechanism.
- Purity Requirement: The 99.97% purity specification must be maintained during handling to avoid contamination.
Why is e-beam evaporation preferred over thermal evaporation for Terbium Oxide (Tb2O3) evaporation material?
E-beam evaporation is preferred for Tb2O3 because of its high melting point (2,387°C) and density (7.87 g/cm³). The product description specifies e-beam evaporation as the primary method, with thermal evaporation available only by RFQ, indicating that the material's refractory nature makes e-beam more suitable for controlled deposition without excessive thermal stress on the source.
What liner or boat materials are compatible with Terbium Oxide (Tb2O3) for evaporation source loading?
The product specifies that Tb2O3 can be evaporated using an e-beam hearth with a graphite, Al2O3, or BN liner, or alternatively with a W, Mo, or Ta boat for thermal evaporation by RFQ. These liner and boat materials are selected to withstand the high melting point and chemical reactivity of the oxide without contamination.
What particle size and purity specifications are available for Terbium Oxide (Tb2O3) evaporation powder?
The material is supplied as a powder with 325 mesh particle size (approximately 44 µm) and a purity of 99.97%. This combination ensures consistent source loading and reproducible film quality in vacuum thin-film deposition, with the 325 mesh size specifically chosen to balance flowability and evaporation rate control.
Terbium Oxide (Tb2O3) evaporation material in 99.97% purity, 325 mesh powder form, optimized for E-beam evaporation with specific hearth liner requirements (graphite/Al2O3/BN) or refractory metal boats, with a high melting point of 2,387°C and density of 7.87 g/cm³, requiring careful deposition-source matching.
Positive
- High purity and defined form: 99.97% purity and 325 mesh powder form ensure consistent evaporation behavior and minimize contamination in thin-film deposition, supporting reproducible film stoichiometry.
- High melting point for thermal stability: Melting point of 2,387°C allows the material to withstand high-energy E-beam evaporation without premature decomposition, suitable for refractory oxide film growth.
Trade-offs
- E-beam evaporation preferred; thermal limited: Thermal evaporation requires RFQ and specific boat liners (graphite/Al2O3/BN or W/Mo/Ta), adding procurement lead time and hardware compatibility checks for non-E-beam systems.
- Powder form requires careful handling: 325 mesh powder may generate airborne particulates during loading, necessitating fume hood or glovebox use to prevent inhalation and cross-contamination in lab environments.
