Cadmium Chloride (CdCl2) evaporation material requires moisture-controlled handling to prevent degradation. Deposition must use a compatible boat or crucible material (W, Mo, Ta, graphite, or alumina) and thermal or resistive evaporation method.
- Moisture Sensitivity: Moisture-controlled handling is required to prevent material degradation during storage and loading.
- Boat Material Compatibility: Use only tungsten, molybdenum, tantalum, graphite, or alumina crucibles to avoid chemical reaction or contamination.
- Evaporation Method Preference: Thermal or resistive evaporation is the preferred method; e-beam evaporation requires a formal quotation for compatibility.
- Particle Size Constraint: The 1–3 mm piece size must be used to ensure consistent source loading and evaporation rate uniformity.
Why is thermal/resistive evaporation preferred over e-beam for Cadmium Chloride (CdCl2) pieces, and under what conditions can e-beam be used?
Thermal/resistive evaporation is preferred due to CdCl2's relatively low melting point of 568 °C, which allows stable, controlled deposition without the high energy density of e-beam that could cause decomposition or spitting. E-beam evaporation is available only by RFQ, likely requiring special handling or process optimization. Moisture-controlled handling is also recommended for this material, indicating sensitivity to atmospheric humidity.
What crucible or boat materials are recommended for evaporating CdCl2, and what handling precautions are necessary?
Cadmium Chloride evaporation material should be used with W/Mo/Ta boats or graphite/alumina crucibles to avoid chemical reaction at the evaporation temperature. The product requires moisture-controlled handling, suggesting the material is hygroscopic or reactive with ambient moisture, so storage in a dry environment and minimal air exposure during loading are advised.
How does the 1-3 mm piece size of CdCl2 evaporation material affect deposition process loading and uniformity?
The 1-3 mm piece size is specified to facilitate consistent loading into thermal boats or crucibles, promoting even melt formation and stable evaporation rates. This size range avoids fine powder that could cause spattering or poor thermal contact, and avoids large chunks that may bridge or expose unheated surfaces. It is a deliberate choice for repeatable thin-film deposition in thermal/resistive systems.
This Cadmium Chloride evaporation material (99.9% purity, 1-3 mm pieces) is optimized for thermal/resistive evaporation using W/Mo/Ta boats or graphite/alumina crucibles, but requires moisture-controlled handling and process verification for e-beam deposition.
Positive
- High Purity 99.9% for Consistent Deposition: The 99.9% purity specification supports reproducible film composition and minimizes contamination in research-grade thin-film deposition.
- Optimized 1-3 mm Particle Size for Source Loading: The 1-3 mm piece size facilitates uniform loading into thermal boats or crucibles, reducing source bridging and improving evaporation rate stability.
Trade-offs
- Moisture-Controlled Handling Required: The material requires moisture-controlled handling to prevent degradation or contamination during storage and loading, adding laboratory infrastructure demands.
- Thermal Evaporation Preferred; E-Beam by RFQ: The material is optimized for thermal/resistive evaporation; e-beam evaporation requires special RFQ approval, limiting deposition method flexibility without prior process validation.
