Direct Deoxidation of ZrOCl2 Powder to Zirconium With Non-Sintering
Direct electro-deoxidation of zirconium oxychloride powder without sintering in molten CaCl2 and NaCl mixture salt was studied. Molten CaCl2 and NaCl mixture salt as electrolyte, a little graphite crucible filled with zirconium oxychloride powder as novel cathode and a graphite rod as anode, deoxidation experiments were performed at 700 and 3.2V for 8h and 15h, respectively. Results show that using new material of zirconium oxychloride and the method of direct electro-deoxidation without sintering can be applied to the preparation of fine zirconium metal particles, which have a great advantage in cheap cost, short technical process, and energy saving.
