Answer:
The correct answer to this question is to increase the electrical conductivity of alumina and lower the fusion temperature to around 1140 K.
Explanation:
Given - The function of fluorspar in the electrolytic reduction of alumina.
To find - what is the function of fluorspar in the electrolytic reduction of alumina?
In the electrolytic reduction of alumina dissolved in fused cryolite, a little amount of fluorspar (CaF2) is added (Na3AlF6). Cryolite and fluorspar boost alumina's electrical conductivity while lowering the fusion temperature to roughly 1140 K.
Fluorspar (CaF2), which is introduced in tiny amounts, plays a crucial role in the electrolytic reduction of alumina dissolved in fused cryolite.
