Sodium Evaporation Material 99.95% Sealed Ampoule ATOMFAIR®

Store the sealed ampoule under inert atmosphere to prevent moisture and air exposure. The material is highly reactive with water and oxygen, requiring strict dry inert handling during all processing steps.

• Inert atmosphere storage: Store the sealed ampoule in a dry inert gas environment (e.g., argon) at room temperature.
• Moisture sensitivity: Sodium reacts violently with water; avoid any contact with moisture during handling.
• Ampoule integrity: Inspect the sealed ampoule for cracks or damage before opening.
• Handling environment: All handling must be performed inside a glovebox with a dry inert atmosphere.
• Evaporation source compatibility: Use only Ta, Mo, or W boats for evaporation under inert handling conditions.

Follow these steps to safely open the sealed ampoule and load the sodium into the evaporation source. All operations must be performed under strict dry inert atmosphere to prevent oxidation or ignition.

Required Equipment: Glovebox with dry inert atmosphere, Evaporation boat (Ta, Mo, or W), Vacuum deposition system, Ampoule opener or cutting tool

1. Inspect ampoule
   Inspect the sealed ampoule for any visible cracks or damage before transferring to the glovebox.
2. Transfer to glovebox
   Transfer the ampoule into a glovebox with a dry inert atmosphere.
3. Open ampoule
   Open the sealed ampoule inside the glovebox by carefully breaking the seal.
4. Load evaporation boat
   Load the sodium metal into a pre-cleaned Ta, Mo, or W evaporation boat using clean tweezers.
5. Evacuate and evaporate
   Transfer the loaded boat to the vacuum deposition chamber, evacuate, and perform thermal evaporation under inert handling.

Sodium (Na) evaporation material (99.95%, sealed ampoule) is a high-purity, reactive metal source for thermal/resistive evaporation under strict dry inert conditions. The low melting point (98°C) and high reactivity demand specialized handling and source hardware, while the RFQ-based sizing requires careful matching to deposition system requirements.

Positive

• High purity 99.95% for consistency: The 99.95% purity specification ensures reproducible film properties in thermal evaporation processes, reducing batch-to-batch variation.
• Sealed ampoule with inert handling: The sealed ampoule form and requirement for dry inert handling preserve the reactive sodium metal from oxidation and moisture contamination, critical for maintaining film quality.

Trade-offs

• Low melting point and high reactivity: With a melting point of 98°C and high reactivity with air and moisture, sodium requires strict inert atmosphere handling and specialized evaporation sources (e.g., sealed ampoule or Ta/Mo/W boat) to avoid safety hazards and film degradation.
• Non-standard size by RFQ: The quantity by RFQ sizing means dimensions are not fixed; buyers must confirm deposition source geometry compatibility with the specific batch to ensure proper loading and evaporation.
