Deposition of this chromium material requires e-beam evaporation with a water-cooled copper hearth. Compatible liner materials are limited to graphite, Al2O3, BN, or Ta to prevent contamination.
- Liner Compatibility: Use only compatible liner materials such as graphite, Al2O3, BN, or Ta with the water-cooled copper e-beam hearth.
- Evaporation Method: E-beam evaporation is the preferred deposition method for this chromium material.
- Process Matching: Match the evaporation source hardware and process route to the material's melting point and film requirements.
What is the significance of the Z-ratio of 0.305 for chromium evaporation in e-beam deposition?
The Z-ratio of 0.305 is an acoustic impedance correction factor used in quartz crystal microbalance thickness monitoring. It ensures accurate film thickness measurement during e-beam evaporation of chromium by compensating for the material's acoustic properties relative to the crystal.
What liner materials are compatible with chromium evaporation in an e-beam hearth?
The product specification indicates that chromium evaporation pellets are compatible with a water-cooled copper e-beam hearth and liners made of graphite, Al2O3 (alumina), BN (boron nitride), or Ta (tantalum).
What evaporation method and source hardware are recommended for these chromium pellets?
E-beam evaporation is the preferred deposition method. The recommended source hardware is a water-cooled copper e-beam hearth, with compatible liners including graphite, Al2O3, BN, or Ta. The pellets are sized 1–3 mm for optimal source loading.
Chromium (Cr) evaporation pellets (99.95%, 1-3 mm) are well-suited for E-beam deposition of hard, wear-resistant coatings, with high purity and consistent pellet geometry. However, the high melting point and specific source compatibility require careful equipment matching and process control.
Positive
- High Purity for Reliable Films: The 99.95% purity specification minimizes contaminants, ensuring consistent thin-film properties in critical applications such as hard coatings or decorative layers.
- Optimized Pellet Size Range: The 1-3 mm pellets facilitate uniform feeding in E-beam evaporation sources, reducing spitting and improving source material utilization.
Trade-offs
- E-beam Source Dependency: This material is optimized for E-beam evaporation; alternative thermal evaporation may require process adjustments or may not achieve equivalent deposition rates.
- High Melting Point (1857°C): The elevated melting point demands high-power E-beam operation and careful thermal management to avoid source damage or film contamination.
