Terbium evaporation material pieces require specific evaporation source hardware and process parameter matching. The 1–10 mm piece size and 99.99% purity must be considered for source loading and film quality.
- Evaporation Source Compatibility: Use only with Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner to avoid material contamination or hardware damage.
- Process Route Matching: Match the evaporation method (e-beam or thermal/resistive) to the material's melting point of 1356°C and Z-ratio of 0.66 to ensure stable deposition rates.
- Physical Form Constraint: The 1–10 mm pieces must be loaded into the source such that they fit within the crucible or boat dimensions without bridging.
- Purity Confirmation: Confirm the 99.99% purity specification meets the film quality requirements for the intended application.
What is the significance of the Z-ratio value of 0.66 for terbium evaporation material in e-beam deposition?
The Z-ratio of 0.66 specifies the acoustic impedance of terbium relative to quartz crystal microbalance calibration, requiring a tooling factor adjustment in the deposition controller for accurate film thickness monitoring. This value is explicitly listed for the product (AF-TBPCS-4N110MM) and must be programmed into the sensor calibration settings to ensure correct rate and thickness measurement during e-beam evaporation. Users should verify that their equipment supports manual Z-ratio input.
What evaporation source configurations are compatible with terbium (Tb) pieces having a melting point of 1,356°C?
Terbium evaporation material is compatible with tantalum (Ta) or tungsten (W) boats, tantalum liners, or water-cooled e-beam hearths with a liner, as stated in the product specifications. The high melting point of 1,356°C requires a source capable of reaching and maintaining that temperature, typically achieved via e-beam or thermal/resistive evaporation. Buyers must confirm source geometry, liner material, and power supply capability with their vendor before ordering.
What handling and storage precautions are recommended for 99.99% pure terbium pieces in thin-film deposition workflows?
Terbium is a reactive rare earth metal that can oxidize in ambient air, so storage under inert atmosphere or vacuum is advised to maintain the 99.99% purity specification. The product is supplied as pieces sized 1–10 mm, which should be handled with clean, non-reactive tools to avoid contamination. The manufacturer recommends reviewing the certificate of analysis, safety data sheet (SDS), and shipment conditions—including any export restrictions—before finalizing laboratory use.
This 99.99% pure terbium evaporation material in 1–10 mm pieces is suitable for e-beam or thermal evaporation, requiring careful source hardware matching and pre-order verification of specifications.
Positive
- High-purity terbium pieces: 99.99% purity ensures consistent film composition and allows direct comparison with standard and high-purity grades for research reproducibility.
- Optimized physical form for evaporation: Pieces with 1–10 mm sizing support reliable source loading and are compatible with Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner.
Trade-offs
- Source hardware compatibility verification required: The material must be matched to specific evaporation source hardware (Ta/W boat, Ta liner, or e-beam hearth); incorrect selection leads to deposition failure.
- Pre-order procurement confirmation needed: Buyers must confirm deposition source geometry, quantity, certificate requirements, and shipment conditions before quotation, adding lead time to procurement.
