Technical Specifications: Structure, Parameters and Quality Standards
Sodium is a silvery soft metal (Na, Atomic No. 11), exhibiting extreme chemical reactivity, especially with water and oxygen, which makes its handling technically robust.
Material & Purity: Industry-grade Sodium is typically supplied at 99.8%–99.99% purity, often packaged oil-sealed in steel drums or ampoules.
Manufacturing Process: Most suppliers use either Downs electrolysis process (molten NaCl) or amalgam process, with enhanced monitoring for trace impurities (Fe, Ca, Mg, etc.) per ISO 11120-8 and ANSI Z358.1.
Standard Form Factors: Cylindrical ingots, rods, spheres, granules; typically packed in 50kg, 100kg, or 500kg units.
Service Life: Up to 8–15 years in sealed systems; depends on handling and process conditions.

Manufacturing Process Flow & Diagram
- Raw NaCl Melting (at 600–610℃) – pure salt is sourced and melted in corrosion-resistant tanks.
- Electrolysis – Direct electric current splits molten NaCl: 2𝑁𝑎𝐶𝑙 → 2𝑁𝑎 + 𝐶𝑙₂↑;
- Sodium Collection – Molten Sodium floats and is drawn off from the top.
- Cooling & Extrusion – The liquid metal is solidified into rods/ingots through controlled casting or CNC-shaped extrusion, minimizing oxide formation.
- Cutting & Packaging – Automatic CNC cutting for uniformity; nitrogen blanketing + oil sealing to prevent oxidation.
- Quality Inspection – Spectrometry, impurity detection and certifications (ISO, ANSI, ASTM) before shipment.
