text: One industrial application is the production of magnesium, which begins with production of magnesium chloride by chlorination of magnesium oxide:
  Electrolysis of the resulting molten magnesium chloride is conducted at 700 °C:
  Aluminium metal is produced from aluminium oxides by electrolysis of a molten mixture of sodium hexafluoroaluminate and alumina at 950 °C. This conversion is called the Hall-Haroult process.
