Sodium metal is highly reactive with moisture and oxygen, requiring storage under mineral oil or inert gas to prevent oxidation and fire hazard. Handling must be performed in a strictly dry inert atmosphere, using sealed ampoules or refractory metal boats to avoid direct exposure to air.
- Storage Atmosphere: Store under mineral oil or inert gas to prevent reaction with atmospheric moisture and oxygen.
- Handling Environment: All handling must be performed in a glovebox or under a dry inert gas blanket to avoid pyrophoric reaction.
- Containment for Evaporation: Use sealed ampoules or Ta/Mo/W boats designed for inert handling to prevent oxidation during deposition.
- Moisture Sensitivity: Avoid any contact with water or humid air, as sodium reacts violently, producing hydrogen gas and heat.
- Temperature Consideration: Sodium melts at 98°C, so heating must be controlled to avoid rapid vaporization or splattering.
This procedure describes the safe handling and evaporation of sodium pieces under inert conditions. Follow these steps to load the material into a refractory metal boat and perform thermal evaporation in a vacuum chamber.
Required Equipment: Glovebox, Tantalum, molybdenum, or tungsten boat, Vacuum deposition system, Inert gas supply
- Transfer to Glovebox
Transfer the sodium pieces from the storage container to a glovebox or inert gas environment. - Inspect Material
Inspect the pieces for any signs of oxidation or contamination before loading. - Load into Boat
Load the sodium pieces into a tantalum, molybdenum, or tungsten boat using inert handling tools. - Seal Assembly
Seal the evaporation source assembly in a sealed ampoule or place the boat in the deposition chamber under inert gas. - Evacuate Chamber
Evacuate the chamber to the required vacuum level for thermal evaporation. - Heat Boat
Heat the boat to a temperature above 98°C to melt and evaporate the sodium. - Monitor Deposition
Monitor the deposition process to ensure the desired film thickness is achieved.
Why is sodium evaporation material stored under mineral oil or inert gas, and how does that affect deposition process parameters?
Sodium (Na) is highly reactive with moisture and oxygen, so it is supplied under mineral oil or inert gas to prevent oxidation and maintain purity (99.9%). During thermal/resistive evaporation, strict dry inert handling is required to avoid contamination. The low melting point of 98°C allows evaporation at relatively low temperatures, but the reactive nature demands controlled atmosphere to prevent rapid oxidation or safety hazards.
What evaporation source materials are compatible with sodium (Na) evaporation pieces under inert handling conditions?
The product is designed for use with sealed ampoules or boats made of tantalum (Ta), molybdenum (Mo), or tungsten (W) in an inert handling setup. These refractory metals can withstand the reactive nature of molten sodium and the thermal cycling during evaporation. The pieces form under mineral oil/inert gas must be transferred to the source without exposure to air.
What are the critical handling and storage requirements for sodium evaporation material to prevent oxidation during vacuum deposition?
The material must be stored under mineral oil or inert gas at all times to prevent oxidation. Handling requires strict dry inert conditions, as sodium reacts vigorously with moisture and air. The low density (0.97 g/cm³) and low melting point (98°C) necessitate careful thermal management—usually using a sealed ampoule or Ta/Mo/W boat in an inert handling setup—to avoid spitting or uncontrolled evaporation during thermal/resistive deposition.
This sodium evaporation material (99.9% purity, pieces under mineral oil/inert gas) is suitable for thermal/resistive evaporation in inert handling setups, requiring sealed ampoule or refractory metal boats to prevent oxidation. Its low melting point (98°C) and high reactivity demand strict dry inert conditions for safe and reproducible thin-film deposition.
Positive
- High purity and defined form: 99.9% purity and pieces form ensure consistent evaporation behavior and reproducible film quality for research-grade thin-film deposition.
- Protective storage under oil/inert gas: Supplied under mineral oil or inert gas to prevent oxidation and moisture absorption, preserving material reactivity and handling safety.
Trade-offs
- Strict inert handling required: Sodium is highly air- and moisture-sensitive, requiring sealed ampoule or Ta/Mo/W boats under dry inert atmosphere for safe evaporation, increasing laboratory infrastructure demands.
- Low melting point constraints: Melting point of 98°C necessitates precise temperature control and may limit compatibility with standard evaporation sources not designed for low-melting, reactive metals.
