Cadmium Iodide (CdI2) evaporation material requires moisture-controlled handling and specific deposition source hardware to prevent degradation and ensure consistent film quality. The material must be processed using thermal or resistive evaporation from compatible boats or crucibles at temperatures near its melting point of 387°C.
- Moisture Control Requirement: Moisture-controlled handling is required during storage and loading to prevent contamination or degradation of the cadmium iodide pieces.
- Deposition Source Compatibility: Deposition source must be a W, Mo, or Ta boat or a graphite or alumina crucible; e-beam evaporation requires RFQ confirmation.
- Operating Temperature Range: The material's melting point of 387°C defines the operating temperature range for evaporation source heating.
- Process Parameter Matching: Process parameters should be matched to the material's density (5.67 g/cm³) and particle size (1-3 mm) to achieve consistent evaporation rates.
- Documentation Review: Review the certificate of analysis and safety data sheet for handling, storage, and disposal requirements specific to cadmium iodide.
Why is thermal/resistive evaporation preferred over e-beam for Cadmium Iodide (CdI2) evaporation material?
Thermal/resistive evaporation is preferred for CdI2 due to its relatively low melting point of 387°C and the risk of thermal decomposition under high-energy e-beam bombardment. The product specification explicitly recommends thermal/resistive evaporation as the primary method, with e-beam available only by RFQ, indicating that e-beam may require additional process optimization. Compatible boat/crucible materials include W, Mo, Ta, graphite, or alumina.
What boat or crucible materials are compatible with CdI2 evaporation, and how should they be selected?
The product specification lists W, Mo, Ta boats or graphite/alumina crucibles as compatible evaporation sources. Selection depends on the evaporation method — thermal evaporation typically uses boats, while e-beam (by RFQ) may require different crucible materials. The specification advises confirming deposition-source compatibility before ordering to avoid chemical reactivity or contamination issues.
What handling and storage conditions are required for Cadmium Iodide evaporation material?
The product specification explicitly requires moisture-controlled handling, indicating that CdI2 is hygroscopic and must be stored in a dry, sealed environment to prevent degradation and maintain film quality. As a cadmium compound, standard laboratory safety protocols for toxic materials — including use of fume hoods, gloves, and eye protection — should be followed during handling and deposition.
This Cadmium Iodide (CdI2) evaporation material is supplied as 99.9% pure 1-3 mm pieces, optimized for thermal/resistive evaporation using W/Mo/Ta boats or graphite/alumina crucibles, with moisture-controlled handling required during storage and deposition.
Positive
- Defined purity and form: 99.9% purity and 1-3 mm piece size provide clear material identity and physical consistency for reliable deposition process matching and source loading.
- Flexible crucible compatibility: Evaporation works with W/Mo/Ta boats or graphite/alumina crucibles, accommodating common thermal evaporation hardware configurations.
Trade-offs
- Moisture-sensitive handling required: Moisture-controlled handling is specified, indicating the material is hygroscopic and must be stored and processed in dry conditions to prevent degradation or outgassing.
- E-beam evaporation only by RFQ: Standard evaporation method is thermal/resistive; e-beam use requires a request for quotation, meaning no direct compatibility and additional lead time or custom engineering.
