The obtained precipitate was calcined to form CaTiO3, which was electrochemically reduced to Ti in the molten CaCl2-CaO. The wasted salt containing CaO could be recycled to form CaTiO3. The operating conditions such as (NH4)2S and tartaric acid concentrations for Fe removal, supplied charge, gas pressure and cooling atmosphere for molten salt reduction were optimized to obtain low-oxygen titanium.Asian Conference on Molten Salt Chemistry and TechnologyConference Paperapplication/pdfhttp://hdl.handle.net/2115/67273https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/67273/1/OA11_Ryosuke%20O.%20Suzuki_Hokkaido%20University.pdfProceedings of the 6th Asian Conference on Molten Salts Chemistry and Technology2017-07-13engpublisher
