Lithium fluoride pieces require moisture-controlled handling to prevent degradation before deposition. Evaporation performance depends on source material compatibility and process route selection.
- Moisture Sensitivity: Moisture exposure must be minimized during storage and handling to maintain material integrity.
- Source Compatibility: Thermal evaporation using tungsten, molybdenum, or tantalum boats or graphite/alumina crucibles is recommended.
- E-beam Evaporation: Electron-beam evaporation is available by request and is expected to yield good film quality.
- Process Parameter Matching: Deposition parameters must be matched to the material's melting point of 845°C, density of 2.64 g/cm³, and Z-ratio of 0.778.
What is the Z-Ratio of LiF evaporation material and why does it matter for thin-film deposition?
The Z-Ratio for this LiF evaporation material is 0.778. This parameter is critical for calibrating quartz crystal microbalances (QCM) during deposition, as it corrects for the material's acoustic impedance versus the sensor crystal, ensuring accurate film thickness and rate monitoring.
What boat or crucible materials are compatible with LiF evaporation?
LiF evaporation material is compatible with tungsten (W), molybdenum (Mo), or tantalum (Ta) boats, as well as graphite or alumina crucibles. Thermal/resistive evaporation is preferred, but e-beam evaporation is available by request (RFQ) with good performance.
What handling and storage conditions are required for LiF evaporation pieces?
LiF is hygroscopic and requires moisture-controlled handling and storage to prevent degradation. The material is supplied in pack sizes of 25g, 100g, 500g, or 1kg and should be kept in a dry environment; shipment conditions should be confirmed before ordering.
The LiF evaporation material (99.9%, pieces, 0.6 mm) is evaluated for vacuum thin-film deposition. It offers good e-beam performance and compatibility with multiple source materials, but requires moisture-controlled handling and pre-purchase source geometry confirmation.
Positive
- High Purity and Defined Form: 99.9% purity and 0.6 mm piece thickness ensure consistent deposition process matching and reliable thin-film quality.
- Broad Evaporation Source Compatibility: Compatible with W/Mo/Ta boats and graphite/alumina crucibles, and supports both thermal/resistive and e-beam evaporation (by RFQ) with good e-beam performance, providing flexibility in hardware selection.
Trade-offs
- Moisture-Sensitive Handling Required: Moisture-controlled handling is specified, indicating sensitivity to ambient humidity that may affect material stability or film quality.
- Pre-Purchase Technical Validation Needed: Buyers must confirm deposition source geometry, required quantity, certificate, and shipment conditions before quotation, adding a pre-purchase coordination step.
