    Abstract: PROBLEM TO BE SOLVED: To reduce the energy consumption in the manufacture by maintaining the dynamic condition of an alkali metal amalgam forming an anode. SOLUTION: A liquid anode preferably maintains its dynamic condition by the stirring under the atmospheric pressure or the pressure slightly higher than the atmospheric pressure, or the circulation by a pump, or the combination thereof. An anode area and a cathode area are separated from each other by a solid electrolyte which is an alkali metal ion conductor through which helium is impermeable. For example, appropriate solid electrolytes in manufacturing sodium include sodium β"-alumina, and sodium p-alumina. The manufacturing temperature is preferably 310-400 deg.C for sodium, and 260-400 deg.C for potassium. The current density during the manufacture is generally >=250 A/m2, but preferably 0.5-10 kA/m2 for sodium, and 0.3-3 kA/m2 for potassium.

    Abstract: PROBLEM TO BE SOLVED: To energically preferably produce sodium and potassium. SOLUTION: This electrolytic cell being a stirred state comprises an alkali metal amalgam-contg. anode, a solid electrolyte having alkali metal ion conductivity and a cathode. The solid electrolyte and the cathode are mutually divided through an electrolytic soln. As the electyrolyte, dissolved NaOH, NaNH2 or a mixture thereof, or dissolved KOH, KNH2 or a mixture of is used, and the solid electrolyte can be selected from the group consisting of sodium β-alumina, sodium β"-alumina and β/β"-alumina or the group consisting of potassium β-alumina, potassium β" and potassium β/β"-alumina.
