Lanthanum evaporation pellets require deposition source compatibility with Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner. Material melting point (921°C), density (6.15 g/cm³), and Z-ratio (0.92) must be matched to the evaporation method and film requirements.
- Deposition Source Compatibility: Evaporation source hardware must be selected from Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner for proper material loading and thermal behavior.
- Evaporation Method Confirmation: E-beam or thermal/resistive evaporation by RFQ is required, and the process route must be matched to the material's melting point and film specifications.
- Pre-Order Verification: Buyers must confirm model, purity, form, size range, pack size, and deposition-source compatibility before quotation to ensure correct procurement.
- Documentation Review: Certificate of analysis, safety data sheet, shipment conditions, and export requirements should be reviewed against laboratory use needs prior to order.
How does the Z-Ratio of 0.92 influence deposition rate control when using Lanthanum pellets in e-beam evaporation?
The Z-Ratio of 0.92 indicates the material's acoustic impedance relative to quartz crystal monitors, which affects thickness monitoring accuracy. For Lanthanum, this value is close to 1, simplifying rate calibration compared to materials with extreme Z-Ratios; however, users should verify tooling factors for their specific deposition system to maintain precise film thickness control.
What evaporation source configurations are recommended for Lanthanum pellets to avoid contamination or poor film quality?
The product is compatible with Ta/W boats, Ta liners, or water-cooled e-beam hearths with liners. For thermal/resistive evaporation, a Ta/W boat is suitable; for e-beam evaporation, a water-cooled hearth with liner prevents reaction with the crucible material. The choice depends on the required deposition rate and film purity, and should be confirmed via RFQ.
What documentation should be reviewed before procuring Lanthanum evaporation material for laboratory use?
Buyers should review the Certificate of Analysis (CoA), Safety Data Sheet (SDS), shipment conditions, and export requirements to ensure compliance with laboratory safety protocols and handling procedures. The product is research-grade with 99.9% purity and pellet form (1–10 mm), so confirming these specifications against application needs is essential before ordering.
Lanthanum (La) evaporation pellets at 99.9% purity with 1-10 mm size range are suitable for vacuum thin-film deposition using E-beam or thermal resistive evaporation. The material requires careful matching to deposition source hardware and process parameters due to its melting point of 921°C and Z-ratio of 0.92.
Positive
- Defined purity and form: Lanthanum supplied as 99.9% pure pellets in 1-10 mm size range, enabling direct procurement matching for thin-film deposition applications without ambiguity.
- Flexible pack sizes: Available in 100g, 500g, and 1kg pack sizes, allowing laboratories to scale material quantity to experimental or production needs.
Trade-offs
- Source hardware compatibility required: Deposition source geometry (Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner) must be confirmed before ordering, as improper selection may cause contamination or process failure.
- Process parameter tuning needed: Melting point of 921°C, density 6.15 g/cm³, and Z-ratio 0.92 necessitate calibration of evaporation rate and power settings, particularly for thermal resistive evaporation, to achieve stable film deposition.
