Cryolite - Wikipedia

Molten cryolite is used as a solvent for aluminium oxide (Al 2 O 3) in the Hall–Héroult process, used in the refining of aluminium. It decreases the melting point of molten (liquid state) aluminium oxide from 2000–2500 °C to 900–1000 °C, and increases its conductivity thus making the extraction of aluminium more economical.aluminum sodium fluoride, aluminum sodium fluoride,,541 aluminum sodium fluoride products are offered for sale by suppliers on Alibaba, of which halide accounts for 88%, other chemicals accounts for 1%.

Cryolite (Sodium aluminum fluoride). TOXNET from Hazardous,

Cryolite (Sodium aluminum fluoride). TOXNET from Hazardous Substances Data Bank.,Inhalation of fluoride poses a potential hazard in workers in primary aluminium production, but the majority of workers are clinically unaffected. Clinical,PRINCIPALLY AN ELECTROLYTE IN PRODN & REFINING OF ALUMINUM;,World Aluminium — Fluoride Emissions,Fluoride emissions , in the form of gaseous hydrogen fluoride and sodium and aluminium fluorides and unused cryolite as particulates, are the major undesirable fume component produced in the aluminium smelting process. Such emissions can be reduced through the use of fume control systems, operational good practice and improved technology. Data UseAluminium - Essential Chemical Industry,The remaining solid aluminium hydroxide is heated in rotary kilns at about 1300 K to produce aluminium oxide (alumina): (c) Synthesis of cryolite and aluminium fluoride. The key to the electrolytic reduction of aluminium is the use of cryolite which dissolves the alumina and thus enables it to be electrolysed. Cryolite is synthesized in several,
