Cryolite na3alf6

Cryolite (Na3AlF6, sodium hexafluoroaluminate) is an uncommon mineral identified with the once-large deposit at Ivittuut on the west coast of Greenland, mined commercially until 1987. See more 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 (old spelling) and nearby Arsuk Fjord, Southwest … See more Besides Ivittuut, on the west coast of Greenland where cryolite was once found in commercial quantities, small deposits of cryolite have also been reported in some areas of Spain, at the foot of Pikes Peak in Colorado, Francon Quarry near Montreal in Quebec See more 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 See more Molten cryolite is used as a solvent for aluminium oxide (Al2O3) in the Hall–Héroult process, used in the refining of aluminium. It decreases the melting point of aluminium oxide from 2000 to 2500 °C to 900–1000 °C, and increases its conductivity thus … See more Web冰晶石. （Cryolite）一种矿物，六氟铝酸钠（Na3AlF6），白色单斜晶系（109摄氏度），微溶于水，能溶于氧化铝，在电解铝工业作助熔剂、制造乳白色玻璃和搪瓷的遮光剂。. 冰晶石是一种 卤化物矿物 ，为钠铝氟化物。. 颜色从无色透明到白色之间，也有淡棕 ...
