This material requires vacuum deposition equipment with compatible source hardware (Mo/W/Ta boat, graphite/alumina crucible, or e-beam hearth). The pellet size of 1-3 mm and melting point of 1495°C must be matched to the evaporation source geometry and thermal capacity.
- Source Compatibility: Use only with Mo/W/Ta boats, graphite/alumina crucibles, or e-beam hearths rated for temperatures above 1495°C.
- Purity Requirement: Maintain 99.95% purity to avoid film contamination; verify certificate of analysis before use.
- Size Range: Confirm pellets of 1-3 mm fit within the crucible cavity or boat pocket without bridging.
- Z-Ratio Calibration: Calibrate deposition rate monitor with Z-ratio of 0.343 for accurate thickness control.
- Melting Point Limit: Ensure evaporation source can reach and maintain 1495°C without exceeding boat or crucible material limits.
Why does the cobalt pellets spec list a Z-ratio of 0.343, and how does that affect e-beam evaporation process control?
The Z-ratio of 0.343 is a material-specific acoustic impedance correction factor used with quartz crystal microbalances to accurately monitor film thickness during e-beam evaporation. This value affects the tooling factor calculation and rate monitoring accuracy; using the correct Z-ratio for cobalt (99.95%, pellets) ensures deposition rate setpoints and thickness readouts match actual film growth on substrates.
Can these cobalt pellets (1-3 mm, 99.95%) be directly used in both thermal resistance boat evaporation and e-beam hearth systems without additional processing?
Yes, the pellets are directly compatible with Mo, W, or Ta boats for thermal/resistive evaporation, graphite or alumina crucibles, and e-beam hearths. The 1-3 mm pellet size is designed for convenient loading into standard boat, crucible, or hearth pockets without prior crushing or remelting, supporting both thermal and e-beam deposition methods as specified.
What documentation should be reviewed before handling these cobalt pellets in a laboratory setting?
Users should review the certificate of analysis to confirm the 99.95% purity and particle size, the safety data sheet for cobalt handling precautions, and shipment condition notes addressing storage and oxidation prevention. Export requirements must also be verified as cobalt is a controlled material in some jurisdictions. These documents support safe, compliant laboratory procurement and usage.
This Cobalt (Co) evaporation material offers 99.95% purity in pellet form (1-3 mm) suitable for thermal and e-beam deposition, with a melting point of 1495°C and density of 8.9 g/cm³; however, the Z-ratio of 0.343 requires QCM calibration and the high melting point demands compatible source hardware.
Positive
- Defined pellet form and size: Supplied as 1-3 mm pellets, this form factor reduces outgassing and spitting compared to powders, enabling controlled loading into thermal or e-beam evaporation sources.
- High purity and source flexibility: The 99.95% purity grade supports consistent thin-film properties, and compatibility with Mo/W/Ta boats, graphite/alumina crucibles, and e-beam hearths allows deployment across multiple deposition systems.
Trade-offs
- High melting point requires robust source: With a melting point of 1495°C, this material demands compatible boat or crucible materials and sufficient power delivery; inadequate thermal management may lead to contamination or incomplete evaporation.
- Z-ratio requires QCM recalibration: The Z-ratio of 0.343 necessitates recalibration of quartz crystal microbalance (QCM) thickness monitors, adding a process setup step to ensure accurate film thickness control.
