This evaporation material requires moisture-controlled handling to prevent hydration and degradation. Deposition must use compatible source hardware such as W/Mo/Ta boats or graphite/alumina crucibles, with thermal/resistive evaporation preferred over e-beam without prior qualification.
- Moisture Sensitivity: Store and handle under dry, inert atmosphere to avoid moisture uptake that can alter evaporation behavior.
- Source Compatibility: Use only W, Mo, or Ta boats or graphite/alumina crucibles to avoid chemical reaction or contamination during evaporation.
- Deposition Method: Thermal/resistive evaporation is the recommended method; electron-beam evaporation requires RFQ confirmation due to material behavior.
- Particle Size Constraint: The 1–3 mm piece size is suitable for uniform source loading and controlled evaporation rate.
- Purity Grade: The 99.9% purity level imposes limits on contamination sources during handling and deposition.
Perform all handling in a moisture-controlled environment to preserve material integrity. Load the pieces into a compatible source boat or crucible and evaporate using thermal/resistive heating under vacuum.
Required Equipment: Inert atmosphere glovebox, Tungsten, molybdenum, or tantalum boat, Vacuum deposition system with thermal evaporation source
- Transfer to dry environment
Transfer the material into a glovebox with dry, inert atmosphere to prevent moisture exposure. - Verify source compatibility
Confirm the deposition source boat or crucible is made of tungsten, molybdenum, tantalum, graphite, or alumina. - Load source boat
Load the 1–3 mm pieces evenly into the boat or crucible to ensure uniform heating. - Set evaporation parameters
Set the chamber vacuum and heating profile based on the material's melting point below 637°C. - Initiate evaporation
Start thermal evaporation and monitor the deposition rate using a quartz crystal microbalance.
Why is thermal/resistive evaporation preferred over e-beam for MgI2 evaporation material, and what conditions allow e-beam use?
Thermal/resistive evaporation is the preferred method for MgI2 due to its melting point below 637 and density of 4.43. E-beam evaporation is available only by RFQ, using W/Mo/Ta boats or graphite/alumina crucibles, because the material's behavior under high-energy electron beam may require controlled handling and process optimization. The 1–3 mm piece size facilitates loading into both thermal and e-beam sources.
Which boat or crucible materials are compatible with MgI2 evaporation, and what handling precautions are necessary?
Compatible source materials include W/Mo/Ta boats and graphite/alumina crucibles. Moisture-controlled handling is explicitly required for MgI2 due to its hygroscopic nature. The material is supplied as 1–3 mm pieces, which are sized to enable efficient loading into these source geometries under controlled conditions.
What are the moisture-controlled handling requirements for MgI2 evaporation material, and how does the piece size affect deposition preparation?
The product specification mandates moisture-controlled handling for MgI2 to prevent degradation. The 1–3 mm piece size is designed to allow efficient loading into thermal boats or e-beam crucibles under controlled atmospheric conditions. The material is supplied in sealed packs (100g, 500g, or 1kg) to minimize moisture exposure before use.
Magnesium Iodide (MgI2) evaporation material in 1-3 mm pieces at 99.9% purity is suited for thermal/resistive vacuum deposition using W/Mo/Ta boats or graphite/alumina crucibles; moisture-controlled handling is mandatory, and e-beam processing requires RFQ.
Positive
- Defined purity and piece size: 99.9% purity and 1-3 mm pieces ensure consistent evaporation behavior and source loading for thin-film deposition.
- Multiple source compatibility: Compatible with W/Mo/Ta boats and graphite/alumina crucibles, supporting both thermal/resistive and RFQ-based e-beam evaporation.
Trade-offs
- Moisture-sensitive handling required: Material requires moisture-controlled handling and storage to prevent degradation, adding laboratory infrastructure requirements.
- E-beam evaporation by RFQ only: E-beam evaporation is not standard; buyers must request a quotation, which may delay procurement and process integration.
