Na3AlF6 White Crystalline Powder Synthetic Cryolite As a Flux For aluminum



Quick Detal:


CAS NO.:7784-18-1

EINECS NO.:232-051-1

Appearance:white needle crystal or powder

Molecular formula:AlF3
Molecular weight:83.89


Melting point :1040℃

Boiling point :1272℃




Frozen stone, also known as sodium hexafluoroaluminate or sodium aluminum fluoride, the molecular formula Na3AlF6, white fine crystals, odorless, solubility than natural cryolite large, the specific gravity of 3, hardness of 2 to 3, the melting point of 1009 degrees Celsius, easy to absorb Damp. Cryolite is mainly used as aluminum electrolytic flux, rubber, abrasive wear-resistant filler, enamel creamer, glass opacifier and metal flux, crop pesticides and so on. Hall-Heroult method is based on the use of cryolite-based fluoride melt as a solvent to produce metal aluminum, so far no other compounds can be found instead of cryolite


1. As a fluxing agent in aluminum product and non-ferrous metal smelting.
2. As an opacifier and auxiliary solvent in the manufacture of enamel and glass.
3. As a wear- resistant filler for resin and rubber-boned abrasive wheels.
4. Used in the production of ferrous alloy and effervescing steel.
5. As a fusing agent in welding material.
6. As an insecticide of crops, etc.




Store in shady and ventilated warehouse.Keep away from kindling and heat source.

Prevent from direct sunlight.Provide with package encapsulation.Deposit separately

from acids and avoid reserving mixedly.




In plastic coating woven bags or woven bags with plastic film inside, 40kgs, 50kgs,or 1000kgs net each, or as per requirement of clients.






Item Content (%)
Fluorine (F) ≥52
Aluminum (Al) 13-15
Sodium (Na) 30-32
Ferric Oxide (Fe2O3) ≤0.02
Silicon Oxide (SiO2) <0.6
Water (H2O) 0.5
Phosphorus Pentoxide (P2O5) ≤0.02





It's mainly used as an adjusting agent for electrolyte in aluminum smelting by fused salt electrolysis, also in ceramic glaze, catalyst and flux of nonferrous metal metallurgy etc.


Competitive Advantage:


Though smelting, casting, hot-rolling, cold-rolling, heat-treatment, finishing and other technology,the heavy melting aluminum and an appropriate quality of alloying elements is processed to light nonferrous metal material which has the characters of fine luster, good looking, light weight, poison less and selflessness, and it also has good properties of transmitting electric current and heat, processing and corrosion-resisting applicability.
