Evaporation of this powder requires an E-beam source with a compatible liner; thermal evaporation is not standard and requires a custom high-temperature crucible by RFQ. The particle size range of 1.5–18 µm must be matched to the deposition source geometry to ensure proper loading and evaporation.
- Evaporation Method Constraint: E-beam evaporation is the preferred method, and thermal feasibility requires a separate RFQ.
- Hardware Compatibility: Use an E-beam hearth with a compatible liner; a high-temperature crucible is needed for thermal evaporation and must be requested by RFQ.
- Particle Size Constraint: The powder particle size of 1.5–18 µm must be compatible with the source loading mechanism to avoid feeding issues.
- Melting Point Consideration: The melting point of 2210 °C dictates the evaporation temperature and requires appropriate source power settings.
- Z‑Ratio for Monitoring: The Z‑ratio of 1.00 is used for quartz crystal microbalance thickness monitoring during deposition.
Confirm deposition source compatibility and review documentation before handling the powder. Match the evaporation source and process parameters to the material's melting point and film requirements.
Required Equipment: E-beam hearth with compatible liner, High-temperature crucible for thermal evaporation (RFQ)
- Confirm Compatibility
Confirm that the deposition source geometry, liner, and crucible are compatible with the powder particle size and evaporation method. - Review Documentation
Review the certificate of analysis, safety data sheet, and shipment conditions to ensure the material meets laboratory requirements. - Match Application
Match the evaporation source hardware and process route to the material's melting point and intended film properties.
How does the high melting point of LaB6 (2,210°C) influence the choice of evaporation crucible and liner material?
The melting point of 2,210°C requires refractory crucible and liner materials capable of withstanding extreme temperatures without contaminating the deposit. The product description specifies that e-beam evaporation requires a compatible liner, while thermal evaporation (available by RFQ) demands a high-temperature crucible, typically fabricated from materials such as tungsten or molybdenum.
Can LaB6 powder be used in thermal evaporation systems, or is it limited to e-beam evaporation?
LaB6 powder is primarily recommended for e-beam evaporation, where it performs well with a compatible liner, as stated in the product description. Thermal evaporation is possible but requires a high-temperature crucible and must be confirmed via RFQ, indicating that feasibility depends on hardware capable of reaching the material's high melting point without degradation.
Why is the particle size range of 1.5–18 µm specified for LaB6 evaporation powder, and how does it affect deposition?
The 1.5–18 µm particle size range is specified to support reliable source loading and consistent evaporation behavior in e-beam deposition systems, as noted in the product description. This size distribution helps ensure uniform feed into the hearth and reduces the risk of splattering or uneven evaporation rates during thin-film deposition.
This Lanthanum Boride (LaB6) powder evaporant offers 99.99% purity and a 1.5-18 µm particle size, optimized for E-beam evaporation with a compatible liner. Its high melting point of 2,210°C enables high-temperature thin-film deposition, though thermal evaporation requires an RFQ feasibility check.
Positive
- High Purity and Defined Particle Size: The 99.99% purity and 1.5-18 µm particle size range ensure reproducible evaporation behavior and film quality in vacuum deposition processes.
- Good E-Beam Performance with High Melting Point: Exhibits good performance in E-beam evaporation with a compatible liner, and a melting point of 2,210°C supports high-temperature thin-film deposition.
Trade-offs
- Thermal Evaporation Requires RFQ Feasibility: The material is optimized for E-beam evaporation; thermal evaporation is not directly supported and requires a request for quote to determine feasibility, adding a procurement step.
- Deposition-Source Hardware Matching Required: The product must be used with a compatible E-beam hearth liner or high-temperature crucible (by RFQ); buyers must verify compatibility with their specific deposition system before ordering.
