Samarium (Sm) evaporation material requires careful matching to deposition source hardware and process route. Deposition-source compatibility must be confirmed based on material melting point and film requirements.
- Evaporation Source Selection: Select an appropriate evaporation source (Ta/W boat, Ta liner, or water-cooled e-beam hearth with liner) to accommodate the material's melting point and physical form.
How does the Z-ratio of 0.89 for samarium (Sm) affect the accuracy of film thickness monitoring during e-beam evaporation?
The Z-ratio of 0.89 is a critical parameter for calibrating deposition rate monitors, such as quartz crystal microbalances, to ensure accurate film thickness control. For samarium, with a density of 7.52 g/cm³, this value must be entered into the controller to compensate for the acoustic impedance mismatch between the crystal and the deposited material. Using the default Z-ratio of 1.0 without adjustment would introduce systematic error in thickness readings.
What evaporation source materials are compatible with samarium (Sm) pieces for high-vacuum deposition?
Samarium (Sm) pieces, sized 1–10 mm, are compatible with Ta/W boats, Ta liners, or water-cooled e-beam hearths with liners. The melting point of 1,074°C requires a refractory source that can withstand high temperatures without reacting with the molten samarium. Tantalum is specifically recommended for its inertness with rare earth metals, minimizing contamination risk during thermal or e-beam evaporation.
What safety and handling documentation should be reviewed before procuring samarium (Sm) evaporation material?
Before procurement, request the certificate of analysis, safety data sheet (SDS), and confirm shipment conditions and export requirements. Samarium is a rare earth metal that can oxidize in air; the product is supplied as pieces to reduce surface area exposure. Standard laboratory handling precautions—including gloves, eye protection, and use in a well-ventilated area or fume hood—are recommended when working with the material.
Samarium (Sm) evaporation material in piece form (1–10 mm) at 99.9% purity is evaluated for use in E-beam and thermal evaporation systems. The material's defined melting point (1,074°C), density (7.52 g/cm³), and Z-ratio (0.89) require careful source matching, but offer reliable performance for thin-film deposition in research labs.
Positive
- High-purity 99.9% samarium pieces: Defined material identity and 99.9% purity enable reliable thin-film deposition with consistent composition across batches.
- Versatile evaporation source compatibility: Suitable for both E-beam and thermal/resistive evaporation using Ta/W boat, Ta liner, or water-cooled e-beam hearth, allowing flexible integration into existing deposition systems.
Trade-offs
- Pre-order compatibility verification required: Buyers must confirm deposition source geometry, boat/liner materials, and handling conditions before quotation to avoid process mismatch.
- Documentation and handling prerequisites: Certificate of analysis, safety data sheet, shipment conditions, and export requirements must be reviewed against laboratory protocols before order placement.
