Sodium Evaporation Material 99.9% Sealed Ampoule ATOMFAIR®

Sodium metal is highly reactive with moisture and oxygen; storage must be in sealed ampoule under dry inert atmosphere. Handling requires strict exclusion of air and moisture to prevent ignition or degradation.

• Storage: Store the sealed ampoule in a cool, dry inert atmosphere below 30°C, away from any moisture sources.
• Handling: Handle only inside an inert-atmosphere glovebox with continuous argon or nitrogen purge to prevent exposure to ambient air.
• Container Compatibility: Use only sealed ampoules or compatible evaporation boats (Ta, Mo, W) for containing the material during processing.
• Reactivity Warning: Avoid contact with water, alcohols, and any protonic solvents as violent reaction may occur.
• Degradation: Exposure to oxygen or moisture causes oxidation and loss of purity; discard material if discoloration or crust formation is observed.

Sodium must be transferred and loaded under strict inert conditions to avoid hazardous reactions. The evaporation process requires thermal/resistive heating under continuously dry inert atmosphere.

Required Equipment: Inert-atmosphere glovebox, Sealed ampoule cutter or opener, Ta/Mo/W evaporation boat, Thermal evaporation system with inert gas supply

1. Transfer to glovebox
   Transfer the sealed ampoule into an inert-atmosphere glovebox filled with argon or nitrogen.
2. Open ampoule
   Open the ampoule inside the glovebox using a suitable tool to avoid shattering and exposure to air.
3. Load evaporation boat
   Load the required quantity of sodium into a pre-cleaned Ta, Mo, or W evaporation boat using inert handling.
4. Set up evaporation
   Transfer the loaded boat to the evaporation chamber and evacuate, then backfill with dry inert gas before heating.
5. Evaporate
   Apply thermal/resistive heating under continuous inert gas flow to evaporate the sodium onto the substrate.

Sodium (Na) evaporation material in sealed ampoule form with 99.9% purity, supplied in 100g, 500g, or 1kg packages for thermal/resistive evaporation under strict dry inert handling. Requires careful handling to prevent oxidation and must be matched to deposition source and inert environment.

Positive

• 99.9% purity for reproducible films: The 99.9% purity specification supports consistent film composition and reduces batch-to-batch variability in vacuum thin-film deposition.
• Sealed ampoule for inert handling: Supplied in sealed ampoule form to prevent atmospheric contamination, enabling safe handling and loading into thermal evaporation sources under inert conditions.

Trade-offs

• Requires strict dry inert handling: Sodium is highly reactive with air and moisture; all handling and deposition must be performed under dry inert atmosphere (e.g., glovebox) to avoid oxidation and safety hazards.
• Low melting point and reactivity constraints: With a melting point of 98°C and high chemical reactivity, evaporation must be conducted using a sealed ampoule or Ta/Mo/W boat in an inert setup, limiting source compatibility and process parameters.
