Preparation and Property of TiO₂ Electrode for Production of Titanium Sponge by FFC Process

The TiO₂ electrode was prepared by using TiO₂ powder, PVA and charcoal powder as raw materials.Porosity of TiO₂ electrode was measured by using the method of water boiling and the phase of the electrode was analyzed.Then several connection modes were disigned for electrolytic experiment and the product of the experiment was analyzed by using XRD.The results show that the porosity of the TiO₂ electrode is more than 50%, the composition of the prepared TiO₂ is nearly rutile TiO₂, the current is larger when a determined electrode connection is employed, and the product contains 98% titanium.
