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]. html += '\n\n'; } 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. EINECS 262-611-0. Pure cryolite itself melts at 1012 °C (1285 K), and it can dissolve the aluminium oxides sufficiently well to allow easy extraction of the aluminium by electrolysis. © John Veevaert, Comments: White translucent crystalline cryolithionite in brown cryolite.

Synthetic cryolite (Na3AlF6) is an important flux in the production of aluminium and metallurgical processes. 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.
