Cryolite, Na 3 AlF 6 , is used in the electrolysis of aluminum oxide because

Cryolite is used in the electrolysis of aluminum oxide because it reduces the energy requirement of the process due to its low melting point. It acts as a solvent to dissolve the aluminum oxide, and by lowering the melting point of the mixture, it reduces the energy required for the electrolysis process.
