Fused mixture of $CaCl_2$ and $CaF_2$

Vedclass · Answer

(A) Calcium is extracted by the electrolysis of a fused mixture of $CaCl_2$ and $CaF_2$. $CaCl_2$ has a high melting point $(772 \ ^\circ C)$,which makes the process energy-intensive. Adding $CaF_2$ (fluorspar) lowers the melting point of the mixture to approximately $650 \ ^\circ C$,which facilitates the electrolysis process and improves the conductivity of the melt.
