This chromium evaporation material is intended for e-beam evaporation in vacuum thin-film deposition. Processing requires a water-cooled copper e-beam hearth with a compatible liner material such as graphite, Al2O3, BN, or Ta to prevent contamination and ensure thermal management.
- Preferred Evaporation Method: E-beam evaporation is the preferred deposition method for this chromium material.
- Source Compatibility: Use a water-cooled copper e-beam hearth with a compatible liner (graphite, Al2O3, BN, or Ta) to avoid crucible reaction.
- Thermal Properties Consideration: Account for the melting point of 1857°C and Z-ratio of 0.305 when tuning deposition parameters.
- Vacuum Environment: Perform deposition under high vacuum to achieve proper film formation and prevent oxidation.
What is the significance of the Z-ratio of 0.305 for chromium evaporation material in e-beam deposition?
The Z-ratio of 0.305 is a material-specific parameter used to calibrate quartz crystal microbalance (QCM) sensors for accurate deposition rate monitoring during e-beam evaporation. This value is explicitly stated in the product specifications for this chromium pellet, and it directly affects film thickness measurement accuracy. The deposition controller must be set to this Z-ratio value to ensure reliable process control.
What liner materials are compatible with chromium evaporation pellets for e-beam evaporation?
This chromium evaporation material is compatible with graphite, Al2O3, BN, or Ta liners when used in a water-cooled copper e-beam hearth. The product description explicitly lists these liner options as compatible, allowing researchers to select the appropriate liner based on their specific deposition system design and process requirements.
What documentation should be reviewed before procuring and using chromium evaporation pellets?
Before procurement, the certificate of analysis, safety data sheet, shipment conditions, and export requirements should be reviewed against the intended laboratory use. The product page explicitly states that these documents can be reviewed to ensure compliance with laboratory-use requirements, safe handling, and proper shipping of the 99.99% pure chromium pellets.
Chromium (Cr) evaporation pellets with 99.99% purity and 1-3 mm size are optimized for e-beam evaporation in vacuum thin-film deposition. The high melting point (1857°C) and Z-ratio (0.305) impose specific equipment and calibration requirements, but the defined physical form and purity ensure reproducible film quality for research applications.
Positive
- 99.99% purity for consistent film properties: The defined 99.99% purity specification enables reproducible electrical and mechanical properties in thin-film applications, critical for research-grade deposition.
- Controlled pellet size 1-3 mm: The 1-3 mm pellet form ensures uniform loading in e-beam hearths and reduces spitting or incomplete evaporation common with irregularly sized particles.
Trade-offs
- High melting point requires e-beam: With a melting point of 1857°C, this material is not compatible with thermal evaporation and requires a high-energy e-beam source, adding infrastructure constraints.
- Z-ratio deviation requires calibration: The Z-ratio of 0.305 differs significantly from 1.0, necessitating careful calibration of quartz crystal microbalance (QCM) thickness monitors for accurate film thickness control.
