This evaporation material requires moisture-controlled handling to prevent hygroscopic degradation during storage and loading. Deposition must be performed using compatible source materials (W, Mo, Ta boat or graphite/alumina crucible) and either thermal/resistive or e-beam methods as specified by the process.
- Moisture Sensitivity: Moisture-controlled handling is required during storage, transfer, and loading to prevent degradation of the material.
- Source Compatibility: Use only W, Mo, or Ta boats or graphite/alumina crucibles for evaporation to avoid contamination and ensure proper thermal transfer.
- Evaporation Method Preference: Thermal/resistive evaporation is the preferred method; e-beam evaporation requires an RFQ and may not be universally compatible.
- Temperature Constraint: The melting point of 1423°C dictates that the evaporation source must achieve and sustain that temperature without degradation.
- Physical Form Handling: The 1–3 mm piece size is suitable for direct loading into boat or crucible sources without additional size reduction.
What are the recommended evaporation methods for CaF2 pieces and why is thermal resistive preferred over e-beam?
The product specification states that thermal/resistive evaporation is preferred, while e-beam evaporation is available by RFQ (request for quotation). The melting point is 1,423°C and density is 3.18 g/cm³, but no further rationale is provided in the source.
Which boat or crucible materials are compatible with CaF2 evaporation to avoid contamination or reaction?
The product is compatible with tungsten (W), molybdenum (Mo), or tantalum (Ta) boats, or graphite or alumina crucibles, as specified in the evaporation source field. This allows selection based on deposition hardware requirements.
Are there any special handling or storage requirements for CaF2 evaporation material due to moisture sensitivity?
Moisture-controlled handling is required, as indicated in the evaporation source specification. The product should be stored and handled under dry conditions to prevent moisture absorption, though specific storage conditions are not detailed in the source.
This Calcium Fluoride (CaF2) evaporation material (99.99%, 1-3 mm pieces) is suited for thermal/resistive evaporation in W/Mo/Ta boats or graphite/alumina crucibles, with e-beam available by RFQ. The high purity supports optical coating applications, but moisture-controlled handling is required due to hygroscopicity, and deposition source geometry must be confirmed before ordering.
Positive
- High purity 99.99% CaF2: The 99.99% purity specification enables reproducible film stoichiometry and low optical loss, critical for UV-to-IR transmissive coatings and protective layers.
- Defined physical form and source compatibility: Supplied as 1–3 mm pieces compatible with thermal/resistive evaporation using W/Mo/Ta boats or graphite/alumina crucibles; e-beam available by RFQ, ensuring clear hardware matching.
Trade-offs
- Moisture-sensitive handling required: The material requires moisture-controlled handling, indicating hygroscopic behavior that can degrade film quality if exposed to ambient humidity during storage or loading.
- Deposition hardware confirmation needed before ordering: Buyers must confirm deposition source geometry, boat/crucible type, and process method (e-beam by RFQ only) to ensure compatibility with existing evaporation systems.
