Terbium Oxide Tb2O3 Pieces 99.9%, 8-110 nm ATOMFAIR®

This evaporation material requires a vacuum deposition environment and compatible source hardware to achieve controlled thin-film formation. The material's high melting point and particle form necessitate pre-qualification of source geometry and contamination control.

• Deposition Source Compatibility: The evaporation source must be selected to match the material's melting point and chemical reactivity, using either an E-beam hearth with graphite, alumina, or boron nitride liner, or a tungsten, molybdenum, or tantalum boat.
• Preferred Evaporation Method: Electron-beam evaporation is the preferred method; thermal evaporation is available by request and requires specific hardware compatible with the material's high melting point.
• Melting Point Consideration: The material's melting point of 2,387°C requires a high-temperature evaporation source and careful thermal management to avoid thermal shock or degradation of the source liner.
• Purity and Contamination Control: The 99.9% purity specification requires clean handling and a contamination-free deposition environment to maintain film quality and avoid introducing impurities.
• Pre-Installation Verification: The physical form (pieces) and size range (8-110 nm) must be verified against the source geometry to ensure consistent evaporation rate and avoid clogging or uneven deposition.

Terbium Oxide (Tb2O3) evaporation material in pieces form with 99.9% purity and 8-110 nm particle size is evaluated for e-beam evaporation deposition of thin films, requiring confirmation of source geometry and liner material compatibility due to its high melting point of 2,387°C and density of 7.87 g/cm³.

Positive

• Defined material identity and purity: Terbium Oxide (Tb2O3) with 99.9% purity enables clear procurement matching for thin-film deposition processes requiring controlled stoichiometry and minimal contaminants.
• Specified physical form and size range: Supplied as pieces with 8-110 nm sizing facilitates consistent source loading and evaporation behavior in e-beam hearths, supporting reproducible film thickness and uniformity.

Trade-offs

• High melting point requires robust hardware: With a melting point of 2,387°C, this material necessitates e-beam evaporation with graphite, Al2O3, or BN liners; thermal evaporation requires RFQ and compatible W/Mo/Ta boats, adding infrastructure constraints.
• Deposition-source compatibility must be verified: Buyers must confirm source geometry and liner material before ordering, as mismatched hardware can lead to incomplete evaporation or contamination, requiring pre-purchase technical review.
