摘要： A process of producing metal that includes adding a quantity of a alkoxide (M(OR)x) or another metal salt to a cathode compartment of an electrolytic cell and electrolyzing the cell. This electrolyzing causes a quantity of alkali metal ions to migrate into the cathode compartment and react with the metal alkoxide, thereby producing metal and an alkali metal alkoxide. In some embodiments, the alkali metal is sodium such that the sodium ions will pass through a sodium ion selective membrane, such as a NaSICON membrane, into the cathode compartment.
