  • In the case of aluminum oxide, dissolving in water prior to electrolyzing would result in hydrogen gas being produced at the hode instead of aluminum. Thus, aluminum oxide must first be melted. It is usually mixed with molten cryolite (Na3AlF6 – m.p. 1012 oC), which reduces its melting temperature significantly (from over 2000oC to 950oC).
