Quick Detal:


Appreciated as the most recommended company, we are engaged in offering Synthetic Cryolite for Abrasive. It is known for its high functionality, compact design and resistance against temperature. As a customer centric organization, we use only quality assured raw material procured from reliable vendors to design the offered product.
• Durability
• Elegant design
• High strength
• Thermal stability




Cryolite (Na3AlF6, sodium hexafluoroaluminate, sodium aluminium fluoride) is an important raw material for the primary aluminium manufacturing used as a flux to dissolve the alumina in the electrolytical metal extraction. Cryolite is also consumed in the abrasives, ceramics and glass industries.

Fluorsid produces granular cryolite by reacting diluted hydrofluoric acid (HF) and aluminium hydrate (Al(OH)3). The H3AlF6 acid is then converted into sodium salt by ion exchange reaction with a sodium chloride solution. After a solid-liquid separation, the slurry of cryolite is calcined in an internally heated rotary kiln. The final product is in the form of pale pink granules. Milled cryolite is obtained from the granular quality after rotary milling.


Fluorsid's cryolite plant has a production capacity of 20,000 MT/y.


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.

Applications As an electrolyte in production of Aluminum





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.
