Chromium pellets require compatibility with water-cooled copper e-beam hearths and graphite, Al2O3, BN, or Ta liners for vacuum deposition. The 3-6 mm pellet size must be verified against the deposition source pocket geometry to ensure uniform loading and evaporation.
- Liner Compatibility: Chromium pellets are compatible with graphite, Al2O3, BN, or Ta liners in e-beam evaporation systems.
- Pellet Size Constraint: The 3-6 mm pellet size must be verified against the deposition source pocket geometry to ensure uniform loading and evaporation.
- Evaporation Method Preference: E-beam evaporation is the preferred method for chromium deposition using these pellets.
- Process Parameter Matching: Evaporation parameters such as beam power and sweep must be matched to chromium's melting point of 1857°C and Z-ratio of 0.305.
What is the significance of the Z-ratio (0.305) for Chromium evaporation pellets in e-beam deposition?
The Z-ratio of 0.305 is used for quartz crystal monitor calibration to accurately measure film thickness during e-beam evaporation. This value, provided for Chromium (Cr) pellets (99.95%, 3–6 mm), ensures correct sensor calibration for precise deposition control. Matching the Z-ratio to the material is critical for achieving target film properties.
Which liner materials are compatible with Chromium (Cr) evaporation pellets for e-beam deposition?
Compatible liner materials include graphite, Al2O3, BN, and Ta, as specified for the water-cooled copper e-beam hearth. The preferred evaporation method is e-beam evaporation, and selecting the correct liner is essential for thermal and chemical compatibility with Chromium at its melting point of 1,857°C. This prevents contamination and ensures stable evaporation rates.
How do the melting point (1,857°C) and density (7.2 g/cm³) of Chromium pellets affect the evaporation process?
The melting point of 1,857°C requires e-beam evaporation as the preferred method to achieve the necessary high temperature. The density of 7.2 g/cm³ influences the material packing in the crucible and the deposition rate behavior. These parameters must be matched to the evaporation source hardware and process conditions to ensure consistent film quality.
Chromium (Cr) evaporation material supplied as 99.95% purity pellets in 3–6 mm size range, optimized for e-beam evaporation using water-cooled copper hearth and compatible liners. This evaluation confirms the material’s suitability for reproducible thin-film deposition when source geometry and process parameters are verified.
Positive
- High purity 99.95% chromium pellets: Defined 99.95% purity allows direct comparison between standard and high-purity grades, supporting deposition-process matching for clean thin-film applications.
- Controlled pellet size 3–6 mm: Narrow pellet size range facilitates consistent source loading and evaporation behavior in e-beam systems, reducing variability in film thickness and uniformity.
Trade-offs
- Deposition source compatibility must be verified: Buyers must confirm deposition source geometry, liner material, and cooling method before ordering to ensure proper evaporation and avoid hardware incompatibility.
- E-beam evaporation preferred method: Material is optimized for e-beam evaporation; alternative thermal methods may require additional process development to achieve uniform deposition at the specified purity and pellet form.
