This material is designed for e-beam evaporation using a water-cooled copper hearth with compatible liners. The 1-3 mm piece size ensures compatibility with standard crucible geometries.
- Evaporation Source Compatibility: The material is compatible with water-cooled copper e-beam hearths and liners made of graphite, Al2O3, BN, or Ta.
- Purity and Form Requirements: The 99.99% purity and piece form are specified to meet thin-film deposition standards for chromium.
- Process Parameters: The melting point of 1,857°C, density of 7.2 g/cm³, and Z-ratio of 0.305 are provided for deposition rate and thickness calibration.
- Sizing Constraint: The 1-3 mm piece size is selected to prevent bridging or uneven evaporation in the crucible.
- Procurement Confirmation: Buyers must confirm deposition source geometry, pack size, and certificate requirements before ordering.
How does the 99.99% purity specification of Chromium (Cr) evaporation material compare to standard and high-purity grades for e-beam thin-film deposition?
The 99.99% purity specification is a research-grade tier that allows comparison between standard, high-purity, and RFQ-controlled grades. This level ensures minimal contamination for sensitive thin-film applications, which is critical for vacuum deposition where film purity directly affects performance. The product is supplied as Pieces with 1–3 mm sizing, and the purity is listed at 99.99% as stated in the technical specifications.
What liner materials are compatible with Chromium (Cr) evaporation pieces when using an e-beam evaporation system?
Chromium (Cr) evaporation material is compatible with a Water-cooled copper e-beam hearth and liners made of graphite, Al2O3 (alumina), BN (boron nitride), or Ta (tantalum). These liner materials are explicitly listed in the product specifications to withstand the 1,857°C melting point of chromium and prevent contamination during evaporation.
What is the recommended form factor and size range for Chromium (Cr) evaporation material to ensure consistent source loading?
The product is supplied as Pieces with a size range of 1–3 mm, which is specified to support source loading and evaporation review for E-beam evaporation systems. This uniform piece size facilitates consistent feeding into the Water-cooled copper e-beam hearth or compatible liners, helping maintain stable deposition rates during vacuum thin-film workflows.
This Chromium evaporation material (99.99%, 1-3 mm pieces) is evaluated for e-beam deposition in research settings, offering high purity and a compatible form factor, but requiring careful source geometry matching and process parameter calibration.
Positive
- High purity 99.99% for controlled deposition: The 99.99% purity specification minimizes contamination in thin-film applications, enabling reproducible film properties for research-grade workflows.
- Optimized physical form for e-beam evaporation: Supplied as 1-3 mm pieces, this form factor facilitates loading into water-cooled copper e-beam hearths and compatible liners, reducing spitting and improving evaporation uniformity.
Trade-offs
- Infrastructure and compatibility requirements: Operation requires a water-cooled copper e-beam hearth with compatible liners (graphite, Al2O3, BN, Ta); mismatch with other source geometries may cause process instability or contamination.
- Precise process parameter matching needed: With melting point 1,857°C and Z-ratio 0.305, users must calibrate e-beam parameters precisely; improper settings can lead to inefficient evaporation or film non-uniformity.
