Lanthanum (La) evaporation material must be used with compatible deposition source configurations, such as Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner. Buyers must confirm model, purity, form, size, pack size, and deposition-source compatibility before procurement to ensure process reliability.
- Source Compatibility: Evaporation source hardware must be matched to the material's melting point and film requirements for both E-beam and thermal/resistive methods.
- Process Parameter Calibration: The Z-ratio of 0.92 must be used for accurate thickness monitor calibration during deposition.
- Pre-Procurement Verification: Deposition source geometry, required quantity, certificate requirements, and shipment conditions must be confirmed before quotation.
- Material Handling: The material should be handled in accordance with the safety data sheet and laboratory use requirements.
- Purity and Size Validation: The listed purity of 99.9% and size range of 1-10 mm must be verified against deposition process specifications.
What is the significance of the Z-ratio of 0.92 for lanthanum in e-beam evaporation?
The Z-ratio of 0.92 is a material-specific parameter required for accurate quartz crystal microbalance (QCM) monitoring during e-beam evaporation. This value, listed in the technical specifications, must be entered into the deposition controller to correctly calculate film thickness. The melting point of 921°C and density of 6.15 g/cm³ also influence the power settings and evaporation rate for this 99.9% pure lanthanum material.
Which source materials are recommended for evaporating lanthanum pieces?
The source explicitly recommends Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner for evaporation of lanthanum pieces. The material is supplied as pieces of 1-10 mm, which is suitable for these configurations. For thermal evaporation, a Ta or W boat is commonly used; for e-beam, a water-cooled hearth with liner is preferred to minimize contamination and alloying. The product's physical form and purity (99.9%) are designed for these deposition methods.
How does the piece size range of 1-10 mm influence loading and evaporation in thermal and e-beam deposition systems?
The 1-10 mm piece size allows controlled loading into boats, crucibles, or e-beam hearths. For thermal evaporation, larger pieces may require longer melting times, while for e-beam, smaller pieces can be used directly without pre-melting. The source states that the buyer should confirm deposition-source geometry compatibility before quotation. Available pack sizes (100g, 500g, 1kg) support scaling from R&D to pilot production.
This Lanthanum evaporation material (99.9% purity, 1-10 mm pieces) is designed for thin-film deposition via e-beam or thermal evaporation, requiring specific source hardware (Ta/W boat, Ta liner, or water-cooled e-beam hearth) for optimal performance and compatibility.
Positive
- High purity with defined physical form: 99.9% purity and 1-10 mm piece size ensure consistent evaporation behavior and reduce contamination sources in vacuum deposition.
- Flexible evaporation source compatibility: Compatible with Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner, allowing integration into various deposition systems.
Trade-offs
- Requires specific source hardware: Evaporation source hardware must be matched to lanthanum's melting point and reactivity; only Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner are recommended, limiting generic boat compatibility.
