This material must be processed using e-beam evaporation with specific liner or boat materials due to poor e-beam performance. All powder handling requires confirmation of source geometry, quantity, and safety documentation before use.
- Evaporation Method Constraint: Use e-beam evaporation preferred; thermal evaporation requires an RFQ for compatibility.
- Source Hardware Constraint: Use an e-beam hearth with graphite, Al2O3, or BN liner, or a W, Mo, or Ta boat to avoid material incompatibility.
- E-beam Performance Limitation: The material exhibits poor e-beam performance, which may affect deposition rate and film quality.
- Pre-Use Confirmation: Confirm deposition source geometry, required quantity, certificate requirements, and shipment conditions before processing.
- Process Route Matching: Match evaporation source hardware and process route to material melting point, density, and film requirements.
Why is bismuth oxide (Bi2O3) rated as having poor E-beam evaporation performance, and what alternative methods are recommended?
Bi2O3 is rated with poor E-beam performance due to its material properties, making thermal evaporation the primary alternative—available by RFQ. The product description explicitly states 'E-beam performance: Poor' and 'E-beam evaporation preferred; thermal evaporation by RFQ', indicating that while E-beam is preferred, thermal evaporation should be considered for this material.
What crucible liner or boat materials are compatible with evaporating Bi2O3 powder in an E-beam system?
For E-beam evaporation of Bi2O3 powder, compatible hearth liners include graphite, Al2O3, or BN, and compatible boats include W, Mo, or Ta. This is specified in the product description under Evaporation Source: 'E-beam hearth with graphite/Al2O3/BN liner or W/Mo/Ta boat'.
How do the melting point (860°C) and density (8.55 g/cm³) of Bi2O3 affect its evaporation behavior in thin-film deposition?
The melting point of 860°C allows Bi2O3 to evaporate at moderate temperatures, while its density of 8.55 g/cm³ influences deposition rate and film density. These parameters must be matched to the deposition source hardware and process requirements, as noted in the product description under Application Matching.
Bismuth Oxide (Bi2O3) evaporation material in powder form with 99.9% purity and 75-195 nm particle size for e-beam evaporation, but e-beam performance is poor and requires specific liner materials; thermal evaporation available by RFQ.
Positive
- High Purity 99.9% for Deposition Consistency: The 99.9% purity specification enables reproducible thin-film composition and minimizes contamination-driven defects in vacuum-deposited layers.
- Controlled Particle Size 75-195 nm: The defined powder size range supports consistent source loading and evaporation behavior, facilitating process repeatability for thin-film deposition.
Trade-offs
- Poor E-beam Evaporation Performance: E-beam evaporation is rated as poor, indicating low deposition rate, material spitting, or unstable melt behavior; requiring off-specification mitigation or alternative methods.
- Hardware-Dependent Evaporation Setup: Evaporation requires specific liner materials (graphite, Al2O3, BN, or W/Mo/Ta boats) and thermal evaporation is only available by RFQ, limiting direct drop-in compatibility.
