The　performance　of　TiCxO1-x　solid　solutions　with　different　O/C　ratio　serving　as　the　anode　in　electrolysis　cell　was　investigated　in　NaCl-KCl　molten　salt.　It　was　found　that　the　electrochemical　dissolution　occurs　from　the　same　potential　for　all　the　TiCxO1-x.　The　valance　of　the　dissolved　titanium　ion　depends　on　the　potential　applied.　Both　the　dissolution　ratio　of　titanium　and　the　by-product　of　the　anode　reaction　are　dependent　on　the　composition　of　the　anode　TiCxO1-x.　For　high　carbon　TiCxO1-x　(x＞0.5),　all　the　titanium　in　TiCxO1-x　dissolves　as　titanium　ions　with　carbon　monoxide　(CO)　and　carbon　(C)　as　the　by-products.　For　low　carbon　TiCxO1-x　(x＜0.5),　carbon　monoxide　and　carbon　dioxide　(CO2)　were　detected　in　anodic　gas,　titanium　partially　dissolves　as　titanium　ion　and　the　remaining　forms　Ti2O3.　The　dissolution　ratio　of　titanium　decreases　with　the　increase　of　oxygen　in　TiCxO1-x.　(c)　The　Author(s)　2019.　Published　by　ECS.
