It ia an ore of aluminium. Mouse Polyakov, V.O. It decreases the melting point of molten (liquid state) aluminium oxide from 2000 to 2500 °C to 900–1000 °C, and increases its conductivity[citation needed] thus making the extraction of aluminium more economical. Drag2 - Resize html += headTags[0].innerHTML; Small clear fragments become nearly invisible when placed in water, since its refractive index is close to that of water. - Cryolite Substance Details. Natriumhexafluoroaluminate [German] Aluminum sodium fluoride (Na3AlF6) Aluminum sodium hexafluoride (AlNa3F6) Aluminum trisodium hexafluoride. 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. Scale: . Cryolite is sodium aluminium fluoride (N a 3 A l F 6 ). Chemical formula: Na3AlF6. Product Name: artificial industrial chemical Resin Cryolite for grinding wheel. EPA Registry Name: Cryolite. [14], Cryolite occurs as glassy, colorless, white-reddish to gray-black prismatic monoclinic crystals. } The rare crystals are equant and pseudocubic, Very common, often repeated or polysynthetic with simultaneous occurrence of several twin laws. Substantial energy is still needed for both heating the materials and the electrolysis, but it is much more energy-efficient than melting the oxides themselves. Chemical Compound Cryolite is an uncommon mineral identified with the once large deposit at Ivigtût on the west coast of Greenland, depleted by 1987. B - Bonds On/Off Scale: Picture size 4 cm. Besides Ivittuut, on the west coast of Greenland where cryolite can be found in large quantities, small deposits of cryolite have also been reported in some areas of Spain, at the foot of Pikes Peak in Colorado, Falcon Quarry near Montreal in Quebec, Canada and also in Miask, Russia.[11][12]. { Chemical Name: Sodium fluoaluminate.

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.[6]. } Powdery or sandy.
