Fox worked for the cryolite company between 1864 and 1905.
On the other hand, the synthetic form of cryolite is chargeable under heading 28.29 as aluminium sodium fluoride.
I am told that cryolite in its natural form is exempt from the charge under heading 25.28.
There cryolite is used, which is sodium aluminium fluoride, and this is probably the most potent localised source of giving a neighbourhood risk.
The work also includes very large amounts of fluorides, which are an essential part of the manufacture of cryolite, one of the materials by which alumina is made into aluminium.
A few ocular prostheses today are made of cryolite glass.
There, she guarded the cryolite minewhich provided ore vitally needed for the production of aluminumfrom the 16th to the 26th.
It is mainly produced as a precursor to aluminum trifluoride and synthetic cryolite.
Cryolite was eventually synthesized, reducing the importance of the mine, and production was finally found uneconomical and discontinued in 1987.
Natural cryolite was historically required for the production of aluminium, however, currently most cryolite used is produced synthetically.
When cryolite is used for the preparation of alum, it is mixed with calcium carbonate and heated.
Molten cryolite was discovered to dissolve alumina at temperatures significantly lower than the melting point of pure alumina without interfering in the smelting process.
The rest is converted into corrosive hydrogen fluoride en route to various organic fluorides, or into cryolite which plays a key role in aluminium refining.
Alucyc technology is waste-free, cryolite and the remaining aluminium oxide could be used in melting of primary aluminium as additives.
He realized that by passing an electrical current through a bath of cryolite and aluminum oxide, the then semi-rare metal aluminum remained as a byproduct.
