This chromium evaporation material is designed for use in e-beam evaporation systems with water-cooled copper hearths and compatible liners. Successful deposition requires matching the material's melting point, density, and Z-ratio to the process parameters.
- Evaporation Source Compatibility: Use this material with water-cooled copper e-beam hearths and liners made of graphite, Al2O3, BN, or Ta for optimal performance.
- Preferred Evaporation Method: E-beam evaporation is the recommended method for depositing this chromium material.
- Material-Process Matching: The melting point (1,857°C), density (7.2 g/cm³), and Z-ratio (0.305) must be considered when setting deposition parameters and film requirements.
- Physical Form Handling: The 1-3 mm pieces are intended for direct loading into the evaporation source, requiring no further size reduction.
How does the Z-ratio of 0.305 influence deposition rate monitoring for chromium (Cr) evaporation material in e-beam systems?
The Z-ratio of 0.305 is a critical parameter for quartz crystal microbalance (QCM) thickness monitoring during e-beam evaporation. It must be entered into the deposition controller to ensure accurate film thickness and rate readings, as it corrects for the acoustic impedance mismatch between the crystal and the depositing chromium film.
What liner materials are compatible with chromium evaporation pieces in an e-beam hearth?
The product is designed for use with a water-cooled copper e-beam hearth, and compatible liners include graphite, Al2O3, BN, or Ta. These materials are specified to withstand the high melting point of chromium (1,857°C) while minimizing contamination and supporting reliable evaporation.
Why are chromium evaporation pieces supplied in a 1-3 mm size range?
The 1-3 mm size range is specified to support source loading and evaporation review in vacuum thin-film deposition workflows. This form factor facilitates even heating and consistent vaporization when used with e-beam evaporation sources, reducing the risk of spitting or uneven deposition.
Chromium (Cr) evaporation material, 99.95% purity, supplied as 1-3 mm pieces for e-beam deposition in vacuum thin-film workflows. The defined form factor and purity support reliable source loading and process matching, but require verification of deposition source hardware compatibility and procurement specifications before ordering.
Positive
- High-purity chromium with defined form: 99.95% purity and 1-3 mm piece size provide clear material identity and physical form for direct loading into e-beam evaporation sources, reducing process variability.
- Specified evaporation source compatibility: Compatible with water-cooled copper e-beam hearth and graphite/Al2O3/BN/Ta liners, enabling integration into standard thin-film deposition hardware.
Trade-offs
- Requires source hardware verification: Deposition source geometry and liner material must be confirmed compatible with the 1-3 mm piece size and melting point of 1857 °C to avoid operational issues.
- Procurement confirmation mandatory: Buyers must confirm model, purity, form, size range, pack size, and deposition-source compatibility before quotation, adding a procedural step for laboratory procurement.
