Lithium (Li) evaporation material is air-sensitive and must be stored under mineral oil or inert gas to prevent oxidation and hydrolysis. Handling requires a strict dry inert atmosphere to avoid hazardous reactions with moisture or oxygen.
- Storage Atmosphere: Store sealed ampoules or containers under inert gas or mineral oil at room temperature.
- Handling Environment: Use only in a glovebox or dry inert atmosphere to prevent exposure to air.
- Material Reactivity: Avoid contact with water, acids, and oxidizing agents that can cause violent reactions.
- Evaporation Source Compatibility: Use only with tantalum, molybdenum, or tungsten boats or sealed ampoules as specified.
- Disposal: Dispose of lithium waste in accordance with local regulations for reactive metals.
These steps ensure safe handling and evaporation of lithium pellets under inert conditions. Proper transfer and loading prevent air exposure and ensure consistent thin-film deposition.
Required Equipment: Glovebox with inert gas atmosphere, Sealed ampoule, Tantalum boat, Molybdenum boat
- Transfer to source
Transfer the lithium pellets from the storage container to a sealed ampoule or boat within a glovebox under inert gas atmosphere. - Load chamber
Load the sealed ampoule or boat into the evaporation chamber while maintaining an inert environment. - Purge chamber
Purge the chamber with inert gas to remove any residual moisture or oxygen before heating. - Evaporate
Heat the source to the melting point of lithium (181°C) to initiate evaporation under controlled conditions.
Why are these 99.99% lithium pellets supplied sealed under mineral oil or inert gas, and what handling conditions are required for evaporation?
Lithium is highly reactive with moisture and oxygen, so the pellets are sealed under mineral oil or inert gas to maintain 99.99% purity during storage. For thermal/resistive evaporation, strict dry inert handling is required, using a sealed ampoule or Ta/Mo/W boat in an inert atmosphere setup to prevent oxidation and ensure film quality.
What evaporation source hardware is compatible with these lithium pellets, and why is a sealed ampoule or boat recommended?
The compatible sources are sealed ampoules or Ta/Mo/W boats, both operated under inert handling conditions. Lithium has a low melting point of 181°C and is highly reactive, so these configurations minimize exposure to air and allow controlled, reproducible evaporation in vacuum deposition systems.
How does the Z-Ratio of 5.9 for lithium affect deposition monitoring with a quartz crystal microbalance?
The Z-Ratio of 5.9 is a material-specific acoustic impedance factor used to correct the mass reading of a quartz crystal microbalance for lithium. Accurate film thickness control during thermal evaporation requires inputting this value into the deposition controller to compensate for the acoustic mismatch between lithium and quartz.
Lithium evaporation pellets with 99.99% purity sealed under mineral oil/inert gas enable high-purity thin-film deposition under strict dry inert handling, though the low melting point (181°C) and high reactivity require careful process matching and atmosphere control.
Positive
- High purity 99.99%: The 99.99% purity specification ensures minimal contamination during thin-film deposition, critical for sensitive electronic or optical layer applications.
- Inert packaging prevents oxidation: Sealed under mineral oil or inert gas storage maintains lithium metal integrity, preventing surface oxidation and allowing stable evaporation performance upon proper handling.
Trade-offs
- Requires strict inert handling: Lithium is highly reactive with atmospheric moisture and oxygen; loading and evaporation must be performed under strict dry inert conditions to avoid degradation and safety hazards.
- Process parameter matching needed: Low melting point (181°C) and low density (0.53 g/cm³) require optimization of evaporation source type and power profile to achieve uniform film deposition, as stated in the product documentation.
