cryolite Na3AlF6 Aluminum sodium fluoride for Chemical
Auxiliary Agent CAS 15096-52-3 1344-75-8 13775-53-6
Cryolite occurs as glassy, colorless, white-reddish to gray-black prismatic
monoclinic crystals. It has a Mohs hardness of 2.5 to 3 and a specific gravity of
about 2.95 to 3.0. It is translucent to transparent with a very low refractive index of
about 1.34, which is very close to that of water; thus if immersed in water, cryolite
becomes essentially invisible.
Cryolite has also been reported at Pikes Peak, Colorado; Mont Saint-Hilaire,
Quebec; and at Miass, Russia. It is also known in small quantities in Brazil, the
Czech Republic, Namibia, Norway, Ukraine, and several American states.
Cryolite was first described in 1798 by Danish veterinarian and physician Peder
Christian Abildgaard (1740-1801); it was obtained from a deposit of it in Ivigtut and
nearby Arsuk Fjord, Southwest Greenland. The name is derived from the Greek
language words κρυος (cryos) = ice, and λιθος (lithos) = stone.[8]The Pennsylvania
Salt Manufacturing Company used large amounts of cryolite to make caustic soda
at its Natrona, Pennsylvania works during the 19th and 20th centuries.
