It is used to decrease the melting point of the mixture because alumina(Al2O3) has a very high melting point around 2323K or 1554°C

Hey !!
Cryolite acts as a solvent. The melting point of alumina is very high. It is dissolved in cryolite which lowers the melting point and brings conductivity .
Good luck !!
