Tin Oxide (SnO2) powder evaporation material requires specific deposition source hardware and process matching due to its high melting point and density. The material is optimized for e-beam evaporation using graphite, alumina, or boron nitride liners, with thermal evaporation available only by RFQ.
- Deposition Source Compatibility: Use an e-beam hearth with a graphite, Al2O3, or BN liner, or a W/Mo/Ta boat for evaporation.
- Preferred Evaporation Method: E-beam evaporation is the preferred method; thermal evaporation requires quotation-based approval.
- Melting Point Constraint: The material's melting point of 1630°C necessitates high-temperature compatible evaporation hardware.
- Z-Ratio Consideration: The Z-Ratio of 1.00 simplifies thickness monitoring but requires confirmation of crystal sensor calibration.
- Particle Size Handling: The 430 nm powder particle size affects source loading uniformity and evaporation rate control.
How does the 430 nm particle size of SnO₂ powder affect its performance in e-beam evaporation compared to thermal evaporation?
The 430 nm particle size is specified to support source loading and evaporation consistency. For e-beam evaporation, performance is rated as Excellent when using an e-beam hearth with graphite/Al₂O₃/BN liner or W/Mo/Ta boat. Thermal evaporation is available by RFQ, but e-beam is preferred due to the material's high melting point (1,630 °C) and density (6.95 g/cm³). The powder form with submicron sizing ensures uniform sublimation and reproducible film thickness under e-beam conditions.
What evaporation source hardware is required for optimal film quality with this SnO₂ powder?
The product is designed for e-beam evaporation as the preferred method, delivering excellent performance with an e-beam hearth lined with graphite, Al₂O₃, or BN, or using a W, Mo, or Ta boat. Thermal evaporation is possible only by RFQ. Buyers must match the deposition source geometry, liner material, and crucible type to the material's melting point (1,630 °C) and density (6.95 g/cm³) to avoid contamination or inconsistent film growth.
What storage and handling precautions are necessary to maintain 99.9999% purity of SnO₂ powder during laboratory use?
As a research-grade powder with 99.9999% purity, SnO₂ should be stored in a dry, inert atmosphere to prevent moisture uptake and particulate contamination. The product is supplied in sealed packs (25 g to 1 kg); after opening, use immediately or store under desiccation. Safety data sheet and shipment conditions must be reviewed to confirm compatibility with laboratory handling protocols, though no specific storage temperature is mandated.
Tin Oxide (SnO2) evaporation material in powder form with 99.9999% purity and 430 nm particle size is evaluated for E-beam evaporation, offering excellent performance with graphite/Al2O3/BN liners or W/Mo/Ta boats, though thermal evaporation requires RFQ and the powder form necessitates careful handling to avoid contamination.
Positive
- Ultra-high purity 99.9999%: The 6N purity specification minimizes trace metal contamination in deposited films, critical for sensitive optical or electronic thin-film applications where impurity levels directly affect device performance.
- Excellent E-beam evaporation compatibility: Rated as excellent for E-beam evaporation with graphite, Al2O3, or BN liners, and compatible with W/Mo/Ta boats, providing flexibility in deposition system integration without requiring specialized hardware.
Trade-offs
- Thermal evaporation requires RFQ: Thermal evaporation is not a standard option and must be requested via RFQ, limiting process flexibility for labs without E-beam capability and requiring additional lead time for feasibility assessment.
- Powder form requires careful handling: The powder form with 430 nm particle size is prone to airborne dispersion and contamination during transfer, necessitating glovebox or fume hood handling and clean loading procedures to maintain purity.
