The two substances that are added along the Alumina to obtain Aluminium from Alumina by Electrochemical cell are ⇒
1. Cryolite
2. Flourspar
1. Cryolite ⇒ Its chemical formula in Na₃AlF₆. It is also the ore of Aluminum and added in electrochemical reduction cell to make the mixture conducting since pure alumina in almost non-conducting.
2. Flourspar ⇒ It decreases the temperature of the mixture from 2020 °C to 1000 °C.
Hope it helps.
