Calcium (Ca) evaporation pellets require deposition using tantalum, molybdenum, or tungsten boats or crucibles with an inert handling package. Process parameters must be calibrated to the material's melting point of 839 °C, density of 1.54 g/cm³, and Z-ratio of 2.62 for consistent film thickness.
- Evaporation Source Hardware: Use only tantalum, molybdenum, or tungsten boats or crucibles for deposition of calcium evaporation pellets.
- Inert Handling Package: The product is supplied with an inert handling package to preserve material integrity during storage and transfer.
- Evaporation Method Selection: Select thermal resistive evaporation or low-power electron beam evaporation by RFQ to match the source hardware and material properties.
- Process Parameter Calibration: Calibrate deposition parameters using the material's melting point of 839 °C, density of 1.54 g/cm³, and Z-ratio of 2.62 for accurate film thickness control.
- Pre-Installation Verification: Confirm the model, purity, form, size range, pack size, and deposition-source compatibility before quotation to ensure proper integration.
What is the significance of the 1-3 mm pellet size for calcium evaporation materials in thin-film deposition?
The 1-3 mm pellet size is optimized for source loading and consistent evaporation rates in thermal and low-power e-beam processes. This size range facilitates uniform heating and minimizes spitting or incomplete evaporation, which is critical for achieving reproducible film thickness and composition when using Ta/Mo/W boats or crucibles.
Is the Atomfair AF-CAPEL calcium evaporation material suitable for e-beam evaporation?
Yes, the material is suitable for low-power e-beam evaporation by request for quotation (RFQ). It is primarily designed for thermal/resistive evaporation, but e-beam compatibility requires RFQ confirmation. The specified melting point of 839°C and use of Ta/Mo/W boats or crucibles with an inert handling package support both deposition methods.
What handling precautions are required for calcium evaporation pellets due to their reactivity?
Calcium is reactive and requires an inert handling package to prevent oxidation and moisture absorption. The product is supplied with an inert handling package, and users should follow safety data sheet (SDS) guidelines. Storage in a dry, inert atmosphere and careful transfer to evaporation sources are recommended to maintain material purity and process reliability.
This Calcium evaporation material (99.99% purity, 1–3 mm pellets) is produced for vacuum thin-film deposition, requiring inert handling and precise source matching to its melting point (839°C) and Z-ratio (2.62) for consistent film quality.
Positive
- High purity 99.99% for consistent film quality: The 99.99% purity specification enables direct comparison between standard and high-purity grades, supporting reproducible thin-film deposition outcomes.
- Defined pellet size for source loading: The 1–3 mm pellet form facilitates uniform source loading in thermal or e-beam evaporation systems, reducing process variability.
Trade-offs
- Requires inert handling and vacuum compatibility: Calcium is highly reactive; the material requires inert handling packages and vacuum deposition systems to prevent oxidation or contamination during processing.
- Process parameter matching needed for consistent deposition: The evaporation source hardware (Ta/Mo/W boat or crucible) and method (thermal or low-power e-beam) must be carefully matched to the material's melting point (839°C) and Z-ratio (2.62) to achieve desired film properties.
