Lithium Evaporation Pellets 99.99%, 1-10 mm ATOMFAIR®

Lithium pellets are highly reactive with moisture and oxygen, requiring strict inert atmosphere storage and handling. All processing must be performed under dry inert gas to prevent oxidation and combustion hazards.

• Storage: Store lithium pellets in a sealed ampoule under inert gas, away from moisture and air.
• Handling: Handle lithium pellets only in an inert-atmosphere glovebox with oxygen and moisture levels below 1 ppm.
• Evaporation Source: Use a sealed ampoule or a tantalum, molybdenum, or tungsten boat designed for inert handling to prevent reaction during heating.
• Thermal Management: Heat lithium gradually under vacuum to avoid rapid oxidation or spitting due to its low melting point of 181°C.

This procedure describes the safe transfer and thermal evaporation of lithium pellets under inert conditions. Follow these steps to prevent oxidation and ensure uniform film deposition.

Required Equipment: Inert-atmosphere glovebox, Tantalum, molybdenum, or tungsten evaporation boat, High-vacuum deposition chamber

1. Transfer to glovebox
   Transfer the sealed ampoule containing lithium pellets into an inert-atmosphere glovebox before opening.
2. Load evaporation boat
   Open the ampoule inside the glovebox and load the lithium pellets into a clean tantalum, molybdenum, or tungsten boat.
3. Transfer to chamber
   Transfer the loaded boat to the deposition chamber under inert gas cover or using a vacuum load lock.
4. Evacuate chamber
   Evacuate the deposition chamber to high vacuum to remove residual gases before heating.
5. Heat gradually
   Heat the boat gradually to above the melting point of 181°C while monitoring chamber pressure for outgassing.
6. Deposit film
   Open the shutter and deposit lithium onto the substrate at the desired rate while maintaining inert conditions.

Atomfair AF-LIPEL-4N110MM is a 99.99% pure lithium pellet evaporation material (1-10 mm) designed for thermal/resistive evaporation under inert conditions, with low density and high Z-ratio requiring careful process calibration.

Positive

• High Purity 99.99% Lithium: 99.99% purity specification supports reproducible thin-film stoichiometry and minimizes contamination in sensitive deposition processes.
• Optimized Pellet Form Factor: 1-10 mm pellet size accommodates standard thermal evaporation sources and allows controlled loading for consistent deposition rates.

Trade-offs

• Reactive Material Handling Requirements: Lithium is highly reactive with air and moisture, necessitating sealed ampoule storage and strict dry inert handling during loading and evaporation to prevent oxidation or safety hazards.
• Low Density and High Z-Ratio: With a density of 0.53 g/cm³ and Z-ratio of 5.9, crystal monitor calibration must be carefully adjusted for accurate film thickness measurement, and the low density may require specialized source design to avoid material loss.
