Cadmium is a toxic heavy metal requiring EHS review before use during evaporation. Use only with a dedicated crucible or liner to prevent cross-contamination, and ensure the deposition source can reach the melting point of 321°C.
- Safety Review: EHS review must be completed before handling cadmium due to its toxicity.
- Dedicated Tooling: Use only a dedicated crucible or liner specified by RFQ to avoid contamination.
- Thermal Requirement: Melting point is 321°C; confirm the evaporation source can reach and maintain this temperature.
- Source Compatibility: Confirm deposition source hardware compatibility with the material form and size before use.
Load cadmium pieces into a dedicated crucible and install in a vacuum deposition system. Evacuate the chamber and heat to the melting point of 321°C for evaporation.
Required Equipment: Dedicated crucible or liner, E-beam or thermal evaporation source, Vacuum deposition system
- Complete EHS Review
Confirm the evaporation method (E-beam or thermal) and complete the required EHS review before handling. - Load Crucible
Load the cadmium pieces into a dedicated crucible or liner specified by RFQ. - Set Deposition Parameters
Set the deposition source to a temperature sufficient to melt cadmium at 321°C, ensuring proper evaporation.
How does the low melting point of Cadmium (321°C) affect its suitability for e-beam versus thermal evaporation?
Cadmium's melting point of 321°C is relatively low for evaporation materials, making it compatible with both e-beam and thermal methods, but only after an EHS review. The density of 8.64 g/cm³ and Z-ratio of 0.682 influence deposition rate and film uniformity. A dedicated crucible or liner must be selected via RFQ to match the specific evaporation method.
What is the significance of the Z-ratio of 0.682 for Cadmium in thin-film deposition?
The Z-ratio of 0.682 is a material-specific parameter used to calibrate quartz crystal microbalance (QCM) sensors for accurate film thickness monitoring during evaporation. This value, combined with the density of 8.64 g/cm³, allows researchers to set appropriate deposition parameters, but the source notes that deposition source hardware and process route should be matched to material behavior.
What documentation and safety procedures are required before procuring and using Cadmium evaporation material?
The product requires an EHS review before use, and a dedicated crucible or liner must be specified by RFQ. Available documentation includes a certificate of analysis, safety data sheet, and shipment conditions, which should be reviewed against laboratory requirements. The procurement checklist also includes confirming model, purity, form, size range, and deposition-source compatibility.
Cadmium (Cd) evaporation material in piece form, 99.99% purity and 1–3 mm size range, is specified for vacuum thin-film deposition; the material requires dedicated crucible/liner procurement and EHS review before E-beam or thermal evaporation use.
Positive
- High purity 99.99%: Controlled purity grade supports reproducible film composition and reduced contamination in sensitive deposition processes.
- Defined piece size 1–3 mm: Consistent piece dimensions facilitate uniform source loading and predictable evaporation behavior in crucible or liner systems.
Trade-offs
- Dedicated crucible/liner required: Evaporation source components must be procured via RFQ for material compatibility, adding lead time and procurement complexity.
- EHS review before deposition: Cadmium toxicity requires mandatory environmental health and safety review prior to E-beam or thermal evaporation, increasing operational overhead.
