How do the melting point (725°C) and density (3.51 g/cm³) of Barium pellets influence the choice of evaporation boat or crucible material?
The melting point of 725°C is relatively low, allowing thermal/resistive evaporation. The density of 3.51 g/cm³ is moderate. The product specification recommends Ta/Mo/W boat or crucible to ensure compatibility with the material's behavior during evaporation. These parameters are critical for matching the evaporation source hardware to the material properties.
What evaporation methods and source materials are recommended for the Barium (Ba) pellets?
The product is designed for thermal/resistive evaporation or low-power e-beam deposition by RFQ. The recommended evaporation source is Ta/Mo/W boat or crucible, with an inert handling package to prevent oxidation. These specifications ensure compatibility with standard vacuum thin-film deposition workflows.
What handling and safety precautions are required for Barium (Ba) evaporation material?
Barium is a reactive metal, so an inert handling package is specified to prevent atmospheric contamination. The product listing advises reviewing the safety data sheet, certificate requirements, and shipment conditions before quotation. Buyers must confirm laboratory use requirements and export restrictions to ensure safe handling and storage.
Barium (Ba) evaporation pellets at 99.9% purity and 1–3 mm size are designed for thermal/resistive or low-power e-beam deposition using Ta/Mo/W boats or crucibles, but require inert handling due to high reactivity and careful process control given the 725°C melting point.
Positive
- High purity and defined pellet size: 99.9% purity and 1–3 mm pellet form enable consistent evaporation rates and film quality for vacuum thin-film deposition.
- Flexible evaporation source compatibility: Compatible with Ta/Mo/W boats or crucibles for thermal/resistive or low-power e-beam evaporation, allowing integration into various deposition systems.
Trade-offs
- Air-sensitive material requires inert handling: Barium is highly reactive with air and moisture, necessitating an inert handling package and vacuum or inert atmosphere during processing to prevent oxidation.
- Melting point and Z-ratio demand process calibration: A melting point of 725°C and Z-ratio of 2.1 require careful source temperature control and quartz crystal monitor calibration to achieve accurate deposition rates and film thickness.
