Glass-Grade Sodium Cryolite Na3AlF6 Low Iron Powder For Anti-Reflective Coating

Jiaozuo Eversim offers glass-grade sodium cryolite (Na3AlF6) with controlled low iron content, developed for the glass and enamel industries. In glass production, cryolite serves as a powerful flux and opacifier, and its use in anti-reflective coatings demands exceptionally low iron to preserve optical clarity. Our glass grade delivers high purity and low trace-metal content, making it suitable for specialty glass, enamel, and optical applications.

• Low Iron Content: Minimized iron preserves glass transparency and color consistency in premium glass products.
• Effective Glass Flux: Lowers melting temperature and improves melt fluidity for efficient glass production.
• Anti-Reflective Coating Use: Supports the production of anti-reflective and specialty optical coatings.
• Opacifying Action: Provides controlled opacity in enamel and opal glass formulations.
• High Purity: Consistent Na3AlF6 content ensures reliable fluxing and predictable glass chemistry.
• Stable Color Performance: Low impurity profile minimizes color drift in clear and tinted glass.

Glass manufacturing where cryolite acts as a flux and opacifier for container, flat, and specialty glass.

Anti-reflective coating production requiring low-iron, high-purity raw materials for optical clarity.

Enamel and ceramic glaze formulations where controlled opacity and low impurity are required.

Packed in 25kg woven bags with PE liner or 1000kg jumbo bags. Custom packaging and private labeling available. Certificates of analysis documenting iron content accompany every shipment.
