Przykłady cryolite

• 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.
