The metal is produced commercially by reducing strontium oxide with aluminium. The strontium is distilled from the mixture. [56] Strontium metal can also be prepared on a small scale by electrolysis of a solution of strontium chloride in molten potassium chloride: [12] Sr 2+ + 2 e − → Sr 2 Cl − → Cl 2 + 2 e −
