Store the sealed ampoule under strictly dry inert atmosphere to prevent oxidative degradation. Open and handle the material only within an inert-gas glovebox to avoid violent reaction with ambient moisture.
- Inert Atmosphere Requirement: The sealed ampoule must be stored and opened in a dry inert atmosphere (argon or nitrogen) to prevent rapid oxidation and moisture absorption.
- Moisture Sensitivity: Sodium reacts violently with water; even trace humidity can cause hazardous reaction and material degradation.
- Containment Integrity: Do not open the ampoule until it is inside the controlled environment to avoid exposure to air.
- Temperature Control: Store below the material's melting point to maintain solid form and away from ignition sources.
Loading sodium into an evaporation boat requires strict inert-atmosphere conditions to prevent hazardous reactions. Follow these steps to safely transfer from ampoule to deposition source.
Required Equipment: Inert-atmosphere glovebox (argon or nitrogen), Tantalum, molybdenum, or tungsten evaporation boat
- Prepare Glovebox
Purge the glovebox with dry inert gas to achieve an oxygen- and moisture-free atmosphere. - Transfer Ampoule
Transfer the sealed ampoule into the glovebox through the antechamber without exposing it to ambient air. - Open Ampoule
Open the ampoule only inside the glovebox using appropriate tools, avoiding contact with the sodium. - Load Boat
Load the sodium pieces into the evaporation boat using clean, dry tweezers or a spatula. - Transfer to Chamber
Transfer the loaded boat to the deposition chamber while maintaining inert atmosphere integrity.
What is the impact of the 99.5% purity specification on the evaporation behavior of sodium in thermal deposition?
The 99.5% purity ensures consistent evaporation rates and film stoichiometry by minimizing volatile impurities. Sodium has a low melting point (98°C) and high vapor pressure, so purity directly affects the stability of the evaporation source. The 99.5% grade is suitable for standard thin-film applications; higher purity grades can be requested via RFQ for more demanding film properties.
What evaporation source materials are compatible with this sodium evaporation material?
The sodium evaporation material is compatible with sealed ampoule sources or boats made of tantalum (Ta), molybdenum (Mo), or tungsten (W) when used in a dry inert handling setup. These materials resist chemical attack from molten sodium and provide stable thermal contact. The inert handling is critical due to sodium's high reactivity with oxygen and moisture.
What handling and storage conditions are required for this sodium evaporation material?
The material is supplied in a sealed ampoule to prevent exposure to air and moisture. It must be stored and handled under a strict dry inert atmosphere (e.g., argon or nitrogen glovebox) to avoid oxidation or safety hazards. The sealed ampoule should only be opened in an inert environment, and the material should be loaded into the evaporation source immediately to minimize exposure.
Sodium (Na) evaporation material in sealed ampoule form with 99.5% purity, designed for thermal/resistive evaporation under strict dry inert handling. The product's low melting point (98°C) and high reactivity necessitate careful handling and RFQ-based procurement for quantity and configuration matching.
Positive
- High purity 99.5% for reproducible films: The 99.5% purity specification allows direct comparison between standard and high-purity grades, supporting consistent film properties in deposition processes.
- Sealed ampoule for moisture-sensitive handling: Supplied as a sealed ampoule to protect the highly reactive sodium metal from atmospheric moisture and oxygen, enabling safe storage and handling prior to deposition.
Trade-offs
- Requires strict inert atmosphere handling: The material must be handled under strict dry inert conditions (e.g., glovebox) during loading and evaporation to prevent oxidation or reaction, requiring specialized lab infrastructure.
- Procurement requires RFQ quotation process: Quantity and configuration are subject to RFQ, meaning buyers must confirm deposition source geometry, required quantity, certificate requirements, and shipment conditions before order placement, adding lead time.
