Ceramic electrodes based on Magneli phases of titanium oxides

Abstract: Monophase and polyphase ceramic materials based on Magneli phases of titanium oxides of composition Ti3O5, Ti4O7, Ti5O9, and Ti6O11 were synthesized. The materials were obtained by mechanical activation of rutile with titanium and additives of niobium, vanadium, and iron, with subsequent sintering both in reductive atmosphere (hydrogen) and in neutral atmosphere (argon) in the temperature interval of 1060-1080°C. The dependences of the potentials of the obtained ceramic samples on time and composition during a… Show more

“…Extensive investigations of titanate compounds have allowed to find many useful applications of them. In particular, the anosovite is a promising candidate in the manufacturing of various electrochemical components such as anodes in solid-oxide fuel cell [7][8][9][10]. It is also suitable as feed material in industrial production of the titanium dioxide pigments [6,[11][12][13].…”

“…2.9. Due to the variety of closely related structures, the formation of an isolated Magnéli phase from reduced TiO 2 is unlikely [184,185]. The exact crystallographic orientation of the layered Magnéli phase will depend on the extent of the sub-stoichiometry with the associated phase.…”

“…Common applications for Magnéli phase Ti n O 2−n are in the form of ceramic electrodes [185,[200][201][202][203][204]. The high concentration of oxygen vacancies results in significant electrical conductivity, which coupled with the corrosion resistance of the oxide make Magnéli phase oxides desired materials.…”
