摘要: Abstract The electrolytic production of Mg from MgO was experimentally and theoretically investigated near 1550 K. experimental work carried out in a SiC cell housed 10 kW solar receiver that located at the focal point concentrating furnace. oxide dissolved either CaF 2 or MgF . cathode Mo anode Pt C graphite evolved as gas, quenched on cooling coils exit reactor collected for analysis. A thermodynamic cycle study indicates ideal thermal efficiency process is 35 percent an inert 39 carbon anode. Experimental results both current-cell potential traces X-ray diffraction verify successful electrolysis Mg. decomposition expected value. As expected, reduced when replaced In experiment with solvent, current 14 measured.
