This zirconium evaporation material requires e-beam evaporation using a water-cooled copper hearth with compatible graphite, Al2O3, BN, or Ta liners. The pellet size of 1-3 mm and material properties impose constraints on source loading, power settings, and deposition rate monitoring.
- Liner Compatibility: Select liner material from graphite, Al2O3, BN, or Ta to ensure chemical compatibility with molten zirconium during evaporation.
- Pellet Size Constraint: Confirm that the 1-3 mm pellets fit within the e-beam hearth crucible to avoid bridging or non-uniform evaporation.
- Melting Point Consideration: The evaporation temperature of 1852°C requires sufficient e-beam power and adequate thermal management of the hearth.
- Z-Ratio Influence: The Z-ratio of 0.6 must be entered into the deposition controller to accurately monitor film thickness during evaporation.
- Process Route: Use e-beam evaporation as the preferred method; alternative methods may require additional validation.
What is the impact of the 99.95% purity level on the evaporation behavior and film quality of Zr pellets?
The 99.95% purity specification ensures minimal metallic impurities that could alter the evaporation rate, melting point (1852°C), or film stoichiometry. This grade is suitable for research-grade thin films where consistent optical, electrical, or mechanical properties are required. Lower purity grades may introduce contaminants that affect film adhesion or performance.
Are these Zr pellets compatible with resistive thermal evaporation, or only e-beam evaporation?
The product description specifies e-beam evaporation as the preferred method, with compatibility for water-cooled copper e-beam hearths and liners such as graphite, Al2O3, BN, or Ta. Due to the high melting point of 1852°C, resistive thermal evaporation may not achieve sufficient temperature for efficient evaporation, and the pellet form is optimized for e-beam sources. Buyers should confirm deposition-source compatibility before ordering.
Zirconium (Zr) pellets at 99.95% purity and 1-3 mm size are suitable for e-beam evaporation in vacuum thin-film deposition, with a melting point of 1,852°C, density of 6.49 g/cm³, and Z-ratio of 0.6, requiring a water-cooled copper e-beam hearth with compatible graphite/Al2O3/BN/Ta liners.
Positive
- High purity 99.95% Zr: Specified purity enables consistent film composition and reduces contamination risk in sensitive thin-film applications.
- Compatible liner material flexibility: Works with graphite, Al2O3, BN, or Ta liners, allowing adaptation to existing e-beam evaporation hardware.
Trade-offs
- Requires e-beam evaporation infrastructure: Melting point of 1,852°C necessitates e-beam evaporation with water-cooled copper hearth; not compatible with resistive or thermal evaporation methods.
- Z-ratio of 0.6 may complicate thickness monitoring: The Z-ratio of 0.6 deviates from unity, requiring calibration adjustment in quartz crystal microbalance (QCM) film thickness monitoring systems.
