Low-Impurity Sodium Cryolite Na3AlF6 99% Purity White Powder for Aluminum Electrolysis

Jiaozuo Eversim supplies low-impurity sodium cryolite (Na3AlF6) engineered for aluminum electrolysis operations that demand the strictest control over iron, silicon, and phosphorus content. Our refined manufacturing process minimizes trace-metal contamination, which helps smelters produce higher-grade primary aluminum and reduces the risk of off-spec metal batches. Each shipment is accompanied by a certificate of analysis documenting impurity levels so that buyers can validate quality before production use.

• Ultra-Low Iron & Silicon: Controlled iron and silicon content below industry thresholds, protecting the purity of primary aluminum produced in electrolytic cells.
• High Na3AlF6 Purity: Consistently 99% minimum sodium hexafluoroaluminate, delivering reliable fluxing performance and stable electrolyte chemistry.
• Stable Molecular Ratio: Adjustable NaF/AlF3 molecular ratio for precise electrolyte conditioning and stable cell operation over long campaigns.
• Consistent Particle Size: Uniform granular and powder grades from 80 to 325 mesh reduce segregation and improve feeding accuracy.
• Low Moisture Content: Carefully dried material minimizes moisture carry-over, protecting cell thermal balance and reducing hydrogen-related defects.
• Full Traceability: Every batch carries a certificate of analysis with impurity data for transparent quality assurance.

Primary aluminum smelting where low-impurity electrolyte is required to meet strict metal purity specifications.

Aluminum electrolysis flux used to condition the molten electrolyte and maintain stable cell voltage and current efficiency.

Refining and casting operations where controlled trace-metal content improves final ingot quality and downstream processing.

Packed in 25kg woven polypropylene bags with inner PE liner, or 1000kg jumbo bags on pallets. Custom packaging and labeling are available. Every lot is sampled and tested before dispatch, and certificates of analysis are provided with each shipment.
