[10] The Pennsylvania Salt Manufacturing Company used large amounts of cryolite to make caustic soda at its Natrona, Pennsylvania works, and at its Cornwells Heights, Pennsylvania, Plant, during the 19th and 20th centuries. C: Formation of cryolite and other aluminofluorides: A petrologic review. 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. Scale: See Photo. Weakly thermoluminescent. Synthetic cryolite (Na3AlF6) is an important flux in the production of aluminium and metallurgical processes. 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.
